Frequently asked questions

Strategies for managing anxiety before and during flight:

1. Preparation: Familiarize yourself with the aircraft, procedures, and your flight plan. Knowledge reduces uncertainty and builds confidence.
2. Breathing Techniques: Practice deep breathing exercises to calm your nerves. Inhale deeply for a count of four, hold for four, and exhale for four. This can help relax you.
3. Talk About It: Share your feelings with your instructor or fellow students. Talking openly can help alleviate anxiety and provide support.
4. Visualize Success: Spend time visualizing yourself successfully completing the flight, from take-off to landing. Positive visualization can help reinforce your confidence.
5. Stay Focused on the Task: Concentrate on flying and following your checklist. Focusing on specific tasks can help take your mind off anxious thoughts.

Checklists are vital tools in aviation for several reasons:

• Safety: They ensure that all essential tasks are completed, minimizing the risk of forgetting critical steps that could lead to accidents.
• Consistency: Using a checklist helps standardize procedures, making it easier for pilots to follow the same steps every time, which enhances safety.
• Confidence: A systematic approach helps pilots feel more organized and reduces anxiety, especially during complex tasks.
• Training Aid: For student pilots, checklists reinforce learning by outlining what to do at each stage of flight, promoting better retention of procedures.

Content

Overview of ailerons, elevator, and rudder:

• Ailerons: These are located on the trailing edge of each wing. Ailerons control the roll of the aircraft. When you turn the control stick to the left, the left aileron moves up and the right aileron moves down, causing the aircraft to roll to the left.
• Elevator: Positioned on the tail, the elevator controls the pitch (up and down movement). Pulling back on the control stick raises the elevator, causing the nose to rise and the aircraft to climb. Pushing the stick forward lowers the elevator, making the aircraft descend.
• Rudder: The rudder is located at the back of the aircraft and controls yaw (left and right movement). Pressing the left rudder pedal moves the rudder left, causing the aircraft to turn left. It’s important for coordinating turns and maintaining straight flight.

Tips for finding the right position in the cockpit:

1. Seat Height: Adjust your seat so that you have a clear view over the dashboard and can see both the runway and horizon.
2. Distance to Controls: Ensure you can comfortably reach the throttle, control stick, and rudder pedals without straining. Your legs should have a slight bend when pressing the pedals.
3. Backrest Position: Set the backrest to provide support for your lower back. Maintaining an upright position can reduce fatigue during longer flights.
4. Headset Fit: Ensure your headset fits comfortably to avoid distraction. A good fit is important for clear communication.
5. Visibility: Adjust your position to maintain a clear view of the cockpit instruments and outside surroundings. Proper visibility is critical for safe flying.

Planning a safe departure

Take – off in an aircraft happens when the plane lifts off the ground and becomes airborne. But there’s more involved in the process than simply leaving the ground. Several steps must be completed beforehand, and the take – off itself is broken down into different stages.

Pre-Take -off Preparations

Preparing for a flight involves thorough checks. Firstly, there’s the paperwork to handle. The pilot will need to book out, different procedures will apply for different airports and this information is available in the CAA AIP or commercial guides such as Pooley’s or Sky-Demon. Weight and balance calculations should be made and all navigation planning completed, and a flight log prepared. If departure or arrival aerodrome are limiting, then performance calculations should be made.

Weather forecasts should be checked to ensure that the flight may be conducted safely within limits.

Aircraft Technical log should be checked for any defects.

NOTAMS should be checked to see if they will impact the planned flight.

 In some cases, and for international flights you will need to file a flight plan and comply with specific requirements. NAC can give guidance and advice on this subject.

If there are passengers onboard, a safety briefing must be conducted, which is legally required, even if brief.

Next, the pilot performs the pre-flight checks. This involves a detailed walk-around of the aircraft, following a checklist and inspecting various components, from the wings to moving surfaces and fuel levels. This step is crucial because, unlike a car, the pilot cannot simply stop in mid-air to address any issues. Ensuring everything is in working order beforehand is vital.

Once the checks are completed, the pilot enters the cockpit, helps passengers board, and ensures that everyone is securely fastened and there are no loose items. Internal checks from the checklist follow, some of which are completed before the engine starts, while others are done once the engine is running.

Once all is ready and (where available obtaining the ATIS) the pilot radios to request radio check and departure clearance, once obtained a request to taxy call is made.

At airfields with only air/ground or AFIS service – request radio check and airfield data from the airfield service as appropriate.

Taxiing and Preparing for Take-off

Taxying is the process of moving the aircraft safely from its parking position to the runway. During this time, all taxying checks should be completed. It is important to clearly understand the taxy route so study the aerodrome chart to ensure that you understand the instructions that you have been given.

Taxying should be done slowly and carefully as accidents while taxying, often due to misjudged wingtip clearance, do happen.

Before reaching the runway or joining a queue of aircraft waiting for take-off, the pilot performs the Power Checks and Pre-take-off checks from the checklist. Again, make sure you know where these checks are to take place.

Once all checks completed and you are at the holding point call, with a Control service ‘ready for departure’ – ATC will either tell you to hold position, or line up on the runway, or clear you for take-off – read back the instruction. They will also give wind direction and speed and notify you of other traffic which may affect you.

Know the service that you are receiving – An Air Traffic Control Service can clear you to do anything including take-off, an AFIS service can only give ‘take-off at your discretion’ and give information on other traffic e.g. ‘C152 on right base – take off at your discretion’ – they will give you wind direction and speed and may advise on known traffic.

Air ground will rely on you to judge when it Is safe to take-off and give no instruction, they may give other information if it is known to them.

Lining Up on The Runway

Regardless of type of service maintain a good lookout for other traffic especially on Final Approach, if unhappy about the situation advise Air Traffic Service that you are holding position. For example ATC may clear you for immediate take-off due traffic on final – if not confident that you can achieve an immediate take-off it is safer not to do so and remain at the holding point!

Carry out memory Checks:

A – Altimeters correctly set

T – Transponder – correct Squawk and Altitude Reporting

P – Pitot Heat on (as required)

L- Landing Lights on

Once on the centreline check runway alignment against DI/HSI.

The Take-off Roll

The take-off roll is the part of the procedure where the plane accelerates on the ground until it reaches the speed necessary to generate sufficient lift for take-off.

Once aligned with the runway, the pilot sets 2000 RPM against the brakes – checks Engine Temps and Pressures and then releases brakes and applies full power. The speed increases and is checked, and the pilot keeps straight on the runway centreline using rudder and in crosswinds into wind aileron until the aircraft reaches the correct rotation speed.  Selecting a suitable reference point ahead and to the side will assist in maintaining the correct ground track after lift – off.

The pilot must then ensure the aircraft climbs at the correct angle and speed. A climb that is too slow can result in a stall, while a climb that’s too steep may prevent the plane from gaining sufficient altitude quickly enough. Achieving the right balance is crucial for safety, as a safe height must be reached as soon as possible. In the unlikely event of an engine failure after take-off, the ability to land safely is greatly diminished if the aircraft is still near the ground.

Aborting the Take-off

Should anything go wrong during the take-off roll, the pilot can abort the take-off by closing the throttle and applying the brakes and coming to a stop before the end of the runway. ATC should be notified of the aborted take-off once at a safe taxy speed. Do not attempt another take-off!

Post-Take-off Procedures

Once airborne, keep one hand on the throttle until at a safe height (at least 200’ AGL) If the flaps were deployed for take-off, they may then be retracted in stages. And a climb at Vy achieved.  Turns on course should be made in accordance with published airfield procedures and taking account of any noise abatement requirements.

Short or Soft Field Take- offs

There are instances where take-off procedures will differ slightly, often due to short runways or soft ground, such as grass airfields. If unfamiliar with these procedures they should be practised with an Instructor before any attempt is made

In short-field take-offs, the pilot must first calculate whether take-off is possible under the current conditions. This is completed by performing performance calculations as part of pre-flight planning. If it isn’t, the attempt must not be made.

In these cases, flaps are used, and the aircraft is lined up to maximise the available runway available. After applying full power while holding the brakes, the aircraft can accelerate in the shortest distance possible.

Once the optimal speed is reached, the aircraft is lifted off and climbs at the best angle of climb (Vx) to clear any obstacles on the ground before, at a safe height retracting the flaps in stages and transitioning to the best rate of climb (Vy).

For soft-field take-offs, the goal is to avoid stopping on the soft ground, such as mud or ice. The take-off roll begins as soon as possible after taxying, and the aircraft is lifted off at the lowest safe speed possible to remain in ground effect until a safe flying speed is reached, minimising the time spent on the soft ground.

Conclusion

In conclusion, take-off is a critical phase of flight that requires careful attention. While generally straightforward, numerous factors can go wrong, and pilots must always approach take-off with caution and precision to ensure a safe and successful flight.

As ever talk to one of the NAC Instructors for advice on safe take-off techniques.

Captain Laurie Ling

Aircraft trim refers to the small adjustments made to the flight control surfaces that help maintain a desired attitude of the aircraft without the pilot having to exert constant force on the controls. Think of it like fine-tuning the controls to ensure the plane flies straight and level.

Importance of trim: Proper trim is crucial for several reasons:

• Reduced Pilot Workload: By adjusting the trim, pilots can fly hands-free for long periods, reducing fatigue.
• Enhanced Stability: Properly trimmed aircraft are more stable and easier to control, especially during long flights or in turbulent conditions.
• Improved Comfort: A well-trimmed aircraft allows for smoother flying, making the experience more enjoyable.

Basic definition and signs of an impending stall: A stall occurs when the aircraft exceeds its critical angle of attack, causing a significant loss of lift. Recognizing a stall is essential for recovery:

• Signs of an Impending Stall:
  • Sound: You may hear a stall warning horn if equipped, indicating you’re nearing a stall condition.
  • Buffeting: The aircraft may start to shake or buffet as it approaches a stall.
  • Nose Position: If the nose begins to pitch up excessively and you’re losing speed, you could be approaching a stall.
• Recovery: To recover, immediately lower the nose to decrease the angle of attack and apply power to regain airspeed then ease out of the dive. 

Landing an aircraft may seem challenging at first, but rest assured, it becomes more intuitive with experience. There are several simple techniques you can begin using immediately to help improve your landings. Here, we’ll explore 16 landing tips for private pilots, along with answers to common questions students often ask.

What You Should Know…

16 Landing Tips for Student Pilots

While quality flight instruction is irreplaceable, there are several skills you can develop on your own when practicing circuits. Below is a collection of 16 tips to help you master smooth landings.

1. Focus on One Thing at a Time

Have you ever tried multitasking and ended up doing both tasks poorly? It’s a similar story in flying. Trying to juggle airspeed, alignment, and altitude all at once can be overwhelming.

Instead, break your landing down into smaller steps. Concentrate on managing one aspect before moving to the next. As you practice, you’ll gradually start coordinating all these elements together.

To get started:

• Set your speed early in the downwind leg, trimming the aircraft so only minor adjustments are needed later.
• Align with the runway as soon as possible, so once your speed is sorted, you can focus on your descent.
• Trim for speed rather than attitude. If you find yourself adjusting too much, try configuring the aircraft a little earlier.

    2. Request a Longer Final Approach

In an aircraft, the more distance you have, the more time you have to make decisions. If you’re feeling pressured, don’t hesitate to ask air traffic control for a longer final approach. This will give you more time to get everything lined up and correct any issues early on, leaving you more time to focus on the approach itself.

     3. Memorise the Take-off Attitude

Many new pilots find judging the flare tricky. A helpful way to get it right is to recall the position of the horizon on the windscreen during takeoff. This is often similar to what you should see when beginning the flare. 

4. Stay Aware of Wind Conditions

Every day in the air is different, particularly when it comes to wind. No two landings will ever be exactly the same because wind speed and direction are always changing. By checking the wind direction and strength (either via METAR or by observing the windsock at the airfield), you can anticipate how the wind will affect your landing. Knowing this in advance will help you mentally prepare for what’s coming.

5. Practise Landings in Daylight

Landing during daylight hours is far easier than at night because you have more visual cues to help with spatial awareness. If you’re still getting the hang of landings, stick to daylight practice to simplify the process.

6. Maintain a Good Scan – Check the Instruments

Professional pilots constantly monitor their surroundings both inside and outside the cockpit. A quick and consistent scan of the instruments, even in VFR conditions, helps catch any trends early. Merging information from the cockpit with your visual observations will enhance your landing accuracy.

7. Look at the End of the Runway

Many student pilots struggle with where to focus their gaze during the flare. As you approach the last 100 feet, direct your attention to the end of the runway. Focusing on distant points makes it easier to judge depth and alignment compared to looking directly over the nose of the aircraft.

8. Keep Your Aim Point Fixed

A steady aim point on your windscreen helps ensure a smooth descent. If your aim point starts to move up, you’re getting too low, and if it shifts down, you’re getting too high. Keep the aim point in the same position and watch it grow in size as you get closer.

9. Use Flaps Wisely

Flaps can be incredibly helpful, but you don’t always need to use full flaps. In windy conditions, using less or even no flaps can make the controls more responsive, giving you extra control to handle the gusts.

10. Monitor the PAPI Lights

Precision Approach Path Indicators (PAPIs) provide guidance on your approach angle. While calibrated for larger aircraft, they can still help light aircraft pilots stay on track before the final flare. A perfect approach will show two white and two red lights—anything more or less signals you’re off the ideal slope.

11. Learn to Handle Crosswinds

Even a slight crosswind can complicate a landing for beginners. The best way to conquer this is practice. Avoiding windy conditions won’t help you improve. It’s best to learn crosswind techniques early on.

12. Stick to the Correct Parameters

Don’t become complacent with your landings. Even if you’re flying at a familiar airfield, always aim for accuracy in your airspeed, altitude, and runway alignment. Getting these right every time ensures you’ll be able to adapt when landing at more challenging airports.

13. Understand What Makes a Good Landing

A good landing isn’t just about a smooth touchdown. It’s about hitting the right speed, attitude, and landing on the centreline at the predetermined point on the runway. Don’t worry if it isn’t always silky smooth—focus on the essentials.

14. Keep Flying Until You’re on the Ground

Don’t stop flying the plane once you begin the flare. Stay focused and in control right up until the wheels touch down. Small adjustments may still be needed during those last few moments to ensure a safe and stable landing.

15. Prepare Your Landing Briefing

Professional pilots always brief themselves before landing. Even if you’re flying solo, talk through the landing, consider any potential challenges, and visualise the approach. Use the acronym WANTEM to help you cover the key aspects:

• Wind
• Aircraft setup
• NOTAMs and navigation aids
• Threats (such as terrain or complex airspace)
• Errors you might make
• Mitigation strategies, including your go-around plan.

16. Set ‘Gates’ for Your Approach

To maintain a stable approach, set checkpoints or ‘gates’ during the descent. These could be altitude or configuration targets at specific points, such as downwind or final approach. By reaching these gates correctly, you’ll know your approach is going smoothly.

Further Frequently Asked Questions

 How Do Pilots Land Perfectly? Landing perfectly comes down to experience. With practice, you develop a feel for what looks and feels right during an approach. Remember, even seasoned pilots sometimes have rough landings, so don’t be discouraged if it takes time.

Why Are My Landings Too Hard? Hard landings often occur due to mistiming the flare. Flaring too late means the plane still has a descent rate when the wheels touch down, resulting in a firm impact. Alternatively, flaring too early can cause the plane to drop onto the runway after losing lift.

How Can I Stop Bouncing on Landing? Bouncing usually happens due to a hard touchdown or flaring at the wrong point. If you do bounce, avoid pulling back sharply—this can worsen the situation. Instead, hold the attitude and allow the aircraft to settle, or initiate a go-around.

Final Thoughts

Anyone can learn to land smoothly with the right techniques and practice. Focus on continuous improvement, seek out good instruction, and apply these tips. You’ll see your landings improve as your confidence grows.

If you have any questions then reach out to your instructor or contact the operations team for advice and support. Dont forget you

Instructor

Tips for effective communication and feedback:

1. Ask Questions: If something is unclear, don’t hesitate to ask your instructor for clarification. Understanding is crucial for safe flying.
2. Be Honest: Share your feelings about the lesson, whether you’re feeling anxious or confident. This helps your instructor tailor their teaching approach.
3. Request Specific Feedback: After performing manoeuvres, ask your instructor what you did well and what you could improve. Specific feedback helps you learn more effectively.
4. Use Clear Language: Communicate clearly and concisely, especially when speaking to air traffic control or your instructor. This is critical for safe operations.
5. Follow Up: After your lesson, review what you learned with your instructor. This reinforces your understanding and helps consolidate your skills.

A logbook is an essential tool for pilots, serving several important purposes:

• Tracking Flight Hours: It helps you record your total flying time, which is crucial for meeting licensing requirements.
• Documenting Experiences: You can log different types of flights, such as solo, dual instruction, and cross-country, showcasing your training progress.
• Reflecting on Progress: Reviewing your logbook allows you to see your development over time, which can be motivating and help you set future goals.
• Meeting Regulations: Many aviation authorities require accurate logging of hours for currency and certification. Keeping an accurate logbook is a legal obligation.

Basic definitions and examples of each type of airspace:

• Controlled Airspace: This is airspace where air traffic control (ATC) provides guidance and services to aircraft. Pilots must communicate with ATC and follow specific procedures. Examples include Class A, C, and D airspace around busy airports.
• Uncontrolled Airspace: In this airspace, pilots can operate without needing to communicate with ATC, allowing for more freedom. However, basic safety regulations still apply. An example is Class G airspace, typically found in rural areas or below certain altitudes.

Night Flying

There can be no doubt that the acquisition of a night rating to your PPL thus allowing you the pleasure of seeing the Norfolk coastline on a beautiful moonlit night will enhance your flying experience and prove a useful skill.

There are however some serious considerations in taking off into the night sky and whilst we should always plan any flight carefully and consider how we might Manage potential Threats and Errors we need to consider the extra potential risks involved in Night Flying and ensure that are vigilant and apply a very sensible rule – IF IN DOUBT DON’T FLY.

Consider how few airfields are open at night in our area … none other than Norwich therefore what will you do if it closes unexpectedly?

This should affect your fuel decisions; you will need to consider that the nearest diversion is probably Southend so you must ensure sufficient diversion fuel and reserves.

Carefully consider the weather – not only consideration of METARS & TAFS but use your understanding of meteorology – cold clear nights can give fantastic visibility but what are the chances of mist or Fog forming?  How easy is it to avoid cloud at night? What is the freezing level? After all flight inadvertently into cloud at night not only brings the risk of disorientation but also the potential for Icing.

Enjoy night flying but remain conscious of the added Threats associated and ensure that you consider how to trap any potential Errors by having effective Mitigations in place.

As ever if you have any questions consult one of NAC’s instructors.

Let’s consider some potential extra hazards involved in night flying and how we might mitigate the risk by looking at this very useful chart produced by the Honourable Company of Air Pilots:

RT Procedures – Airfield Types of Service

Learning the correct use of the aircraft radio can often seem a daunting task – we are quite correctly taught to AVIATE – NAVIGATE – COMMUNICATE. i.e. we should of course ensure that the aircraft is safely under control and ensure that we know our location as our priorities before communicating.

CAP 413 is the CAA publication detailing radiotelephony procedures and forms the basis of the RT examination that forms part of student training. It is important therefore that this is studied alongside your practical training in the aircraft to gain proficiency. Like all skills the key is to practice, some of this can be gained on the ground – either with an instructor or a friend using the various scripted exchanges in CAP 413.

Here at Norwich, we are used to an Air Traffic Control Service but as we start to explore other airfields during our Navigation exercises, we will encounter different levels of service, and it is important that we understand the difference and the correct terminology.

Air Traffic Control ATC

As in the title it is a ‘Control’ service. Calls therefore are to request a clearance and to read back and comply with the clearance issued by the controller. You must always use the aircraft full callsign (e.g. GBSSC) until it is abbreviated by the controller (e.g. GSC) after which you may use the abbreviated callsign. GROUND, TOWER, APPROACH, RADAR, DIRECTOR frequencies are Control frequencies.

The key point is that you are required to comply with a control service and follow the instructions issued by the controller.

(provided it is safe to do so – you can state ‘unable- stating the reason’  if the clearance you are given would result in an unsafe situation, e.g. compliance with the instruction would result in you no longer being able to fly in VMC).

Aerodrome Flight Information Service AFIS

This is not a control service. It provides information to ensure safe conduct of traffic within the ATZ and will give airfield data – runway in use and QNH, taxying instructions on the apron and airfield manoeuvring area will also be given and must be read back and complied with.

It cannot issue Clearances to Take Off or Land, such calls as ready for departure or final will receive the reply “At your Discretion”. If traffic is known to the AFIS officer (AFISO) then it will be passed to the pilot, e.g.

“GBSSC take off at your discretion – Cessna 152 right hand downwind”

“GBSSC land at your discretion”

If you consider it safe to take off or land, then you would reply

“GBSSC taking off”

“GBSSC Landing”

The key point is that the AFISO cannot ‘Clear you to land or take-off’ but can advise on information known to the AFISO

If flying into an airfield with an AFIS service, before entering the ATZ you should request airfield information – the AFISO will inform you of QNH, Runway in use and any known traffic – but cannot issue joining instructions. It is important that you inform the AFISO of entry into the ATZ, follow any published procedures  and make all normal calls in the circuit.

INFORMATION is the designator for airfields with this type of service.

Air/Ground Communication Service (AGCS)

The radio operator may not be able to view any part of the airfield or airspace and may also be engaged in other airfield related tasks. Any information that may be provided is primarily related to reports made by pilots.

A pilot may request information whilst on the ground or in the air, but such information may not be available, or you may receive no reply at all. The pilot therefore will need to act on their own discretion ensuring that they comply with the Rules of the Air.

It is still important that the pilot clearly states their intentions on the published frequency, thus other traffic operating within the ATZ is aware.

The key point here is that you may receive very limited or no information at all, you will be acting on your own discretion in accordance with the Rules of the Air.

If flying into an airfield with an AGCS service, before entering the ATZ (if one exists) you should request information, if no reply received broadcast when entering the ATZ and comply with published circuit procedures making all normal circuit calls – you may receive no reply but it will ensure any other traffic is aware of your intentions.

RADIO is the designator for airfields with this type of service.

Planning

From the foregoing you can see that is very important when planning to visit other airfields that you clearly understand the level of service provided. Ensure that you have read the UK AIP entry for the airfield and any other available documents before your flight. Many airfields have webpages giving details of their procedures or supply a phone number to contact to obtain that information.

The level of service provided also dictates the RT calls that you will be required to make and therefore a careful study of CAP 413 will give you the knowledge required.

Understanding the Pitot-Static system

The Pitot-Static system is a critical component in the aircraft, providing the pilot with essential data for safe and accurate flying. Here is a quick look at how it works and why it is so important.

• What is a Pitot Tube? – The Pitot tube measures dynamic pressure, that is the pressure from the air as the aircraft moves forward. It does this by being positioned outside the aircraft facing the airflow. It measures the airspeed by comparing this with the static pressure. The difference between dynamic pressure and static pressure is indicated on the airspeed indicator. Thus, Indicated Airspeed.

• What is the Static Port? – The static port measures static pressure, that is the ambient pressure at the aircraft’s altitude. It is located outside the airflow to avoid any airflow impact thus providing an accurate reading of the pressure that changes with altitude.

• Altimeter, Vertical Speed Indicator, Airspeed Indicator – These three critical instruments rely on the Pitot Static system:

The Airspeed Indicator using the difference between dynamic and static pressure to show how fast the aircraft is moving relative to the air.

The Altimeter measures altitude based on changes in the static pressure as the aircraft climbs or descends.

The Vertical Speed Indicator shows the rate of climb or descent by comparing static pressure changes over time.

• Safety – A reliable Pitot-Static system is crucial for safe flight. If either Pitot or Static ports are blocked with debris or ice it can lead to inaccurate readings of the instruments which can be very dangerous.

• Checks – This is why Pitot and Static Ports should be carefully checked during your pre-flight inspection, also in the cockpit carefully check all instruments to ensure that glass is unbroken and not loose as any ‘leaks’ in the system will lead to inaccurate readings of the pressure instruments

Captain Laurie Ling

Best Rate of Climb (Vy) and Best angle of Climb (Vx)

Rate of Climb – This refers to how quickly an aircraft increases its altitude typically expressed in feet per minute; it is measured vertically in terms of altitude gained over time and thus how quickly an aircraft can gain altitude after take-off.  Given normal operating conditions, sufficient runway length and no obstacles in the climb out path it represents normal operation to climb at Vy.

Angle of Climb – this refers to the angle at which the aircraft climbs relative to the horizontal plane, it represents a steeper climb angle thus it is a geometric relationship between altitude gained and horizontal distance covered. It is generally used when operating from airfields where there is a requirement to ensure safe clearance from obstacles in the climb out path. We would therefore plan to climb at Vx under specific circumstances where obstacle clearance is a consideration.

When we are planning our flight, we should carry out performance calculations using the Pilots Operating Handbook (POH) as both are influenced by factors such as Engine Power, Weight and atmospheric conditions such as temperature, pressure, wind and the aircrafts configuration.

These factors must then be considered in relation to the runway in use and any obstacle clearance required in the climb out path to determine (a) can we depart safely (b) the correct technique to use.

Example

Wind at 2000ft is 120/30. The track to our destination is 230°T. The distance to fly is 85nm.

Setting the Wind

1. Put the wind direction under the index, in this case 120°.
2. Move the Slide so that a thick line is under the blue centre In this case, we use the 100 line.
3. Mark the wind speed down from the blue circle, here by 30 knots, on the 70 line. We have circled it to make it easier to see.

Adding you track to the CRP 

1. Move the slide to put the TAS under the blue centre circle (We’ve used 90 knots).
2. Move the inner circle till your track (230°) is under the index.
3. Note the wind velocity is showing a 16° drift to the right.

Balancing drift and working out ground speed

1. As there is 16° of drift to the right, we move the inner circle 16° to the right (214°).
2. The drift moved showing 18° drift to the right, so we’ve moved the inner circle 2° more to the right (212°).
3. You will notice the track (230°) on the inner circle is under the 18° drift line on the outer circle. This is balanced with the drift showing on the wind face.
4. Read the groundspeed of 96 indicated under your velocity mark.

Calculating time (Calculator side)

1. Put the 60 index on the inner circle under your ground speed (96 knots).
2. Put the cursor on the 85nm (the distance from the example) and read off how long it will take on the inner circle (53minutes).

Now you try

Wind at 2000ft is 240/25. The track to our destination is 190°T.

The distance to fly is 45mn. Use a TAS of 95 knots.

Understanding altimetry settings is key to flying safely and precisely. Breaking down the basics:

QFE – Altimeter set to the pressure at the airfield showing the height above that specific airfield.

QNH – Altimeter set to Sea Level Pressure by region showing altitude above mean sea level. It is important that the correct regional QNH is set.

QNE – Altimeter set to 1013 Hpa, commonly used above the transition altitude. Altitudes are then expressed as Flight Levels.

ISA – A standardised model in aviation that defines baseline atmospheric conditions for altitude and pressure settings. ISA assumes sea level pressure of 1013.2 Hpa and a temperature of 15 degrees Celsius with temperature decreasing by 2 degrees per 1000 feet.

Transition Altitude – The altitude at which pilots switch from using QNH to QNE.

Transition Layer – The zone between Transition Altitude and Transition Level ensuring that there is no conflict between aircraft climbing to Flight Levels and those descending to Altitudes.

Transition Level – The lowest useable Flight Level above Transition Altitude, on descent pilots switch from QNE to QNH at the transition level.
