Performance Based Navigation (PBN) Course

Package Details

Course Fees:

  • NAC Aircraft = £1749
  • Own Aircraft = £879
  • Deposit  £150, (A separate link will be sent for the remaining course fee will be sent before course commencement date.)
  • NAC’s Terms and Conditions are available on our website

 

Course Purpose:

Given that the introduction of new airspace procedures lags behind aircraft capability, the use of area navigation systems (FMS on larger aircraft) provides a means for applying an alternate means of primary navigation on conventionally defined routes, procedures and path segments, pending the introduction of permanent PBN procedures. These systems rely upon use of either a “fix” or a Coded Overlay to apply a technique referred to as RNAV substitution.
This module is tailored to UK airspace and regulatory requirements to ensure pilots understand and can implement PBN effectively and RNAV substitution

By the end of this module, participants will be able to safely use PBN systems and substitute GNSS for conventional navigation aids referred to as RNAV substitution, in compliance with UK CAA regulations and ICAO standards.

Minimum Requirements:

  • You must be in current practice with instrument flying
  • You should be familiar with GTN 650 and G5 PFD/HSI
  • We can assist with some re-training/familiarisation if needed with the above so please don’t worry. Just contact us and tell us what you need

 

If you wish to use your own aircraft the following criteria must be met:

  • Your aircraft must have GTN 430 or later
  • The database must be up to date
  • Your aircraft insurance must cover flight training – we will need to see a copy of your documentation.
  • The Nav display must be capable of GPS indications.

 

Course Module Outline

  • Introduction to RNAV Substitution
  • Definition of RNAV substitution – RNAV substitution involves using onboard RNAV systems to replace or replicate conventional ground based navigational aids (VOR, NDB, DME) for navigation and approach procedures
  • Regulatory framework and guidance –
    • UK CAA guidance and regulations (CAP 773, CAP 1781) CAA safety Sense leaflet 25
    • ICAO PBN Standards (ICAO document 9613)
    • General requirements and Guidance Material for the use of RNAV substitution CAP 1926

 

RNAV Substitution Equipment and Certification

  • Equipment Requirements:
    • RNAV systems certified to RNAV 1, RNP 1 or Advanced RNP
    • RNAV substitution is restricted to operators/pilots authorised for either RNAV 1, RNP 1 or Advanced RNP
    • NAC PA28 Fleet meets this requirement
    • Approved GNSS systems
    • Navigation database current and compliant
    • All such equipment must meet UK CAA certification standards
    • Pilot proficiency and training per CAP 773
  • Key System features
    • Ability to programme and fly RNAV defined waypoints
    • Integrity monitoring (RAIM or SBAS availability)

 

Authorised Uses of RNAV Substitution

  • Navigating via RNAV waypoints during enroute segments
  • Determination of aircraft position relative to or distance from a VOR, a Marker, a DME fix, a named fix defined by a VOR radial or NDB bearing and DME distance
  • Navigating to/from a VOR, NDB, or DME waypoint using RNAV-derived data
  • Identifying position over conventional fixes defined by radials or bearings (VOR radials or NDB bearings and DME distance)
  • Where a route or procedure is defined by reference to conventional radio NAVAIDS and coded as an overlay which may be selected from the navigation database and executed:
    • Flying a departure or arrival route (SID’s, STARS)
    • Flying DME arcs or holding pattern using RNAV
    • Flying the initial, intermediate or missed approach segments of an Instrument Approach Procedure (IAP)

 

Limitations and Restrictions in UK airspace

  • RNAV substitution is not permitted for:
    • Localiser-based approaches (e.g., ILS, LOC )
    • Final approach segments without a published RNAV overlay
    • When NOTAMs or charts explicitly prohibit substitution
  • GNSS Integrity must meet procedure – specific requirements (RNAV 1 for terminal procedures)
  • RAIM outages or loss of GNSS signal integrity may prohibit substitution

 

Operational Procedures for RNAV substitution – Responsibility of pilot-in-command

  • Preflight Preparation:
    • Verify database is current and waypoint accuracy
    • Ensure that waypoints and procedures to be used are retrieved from the navigation database
    • Verify waypoint sequencing, reasonableness of track angles, and distances of any coded overlay procedures used and particularly, where the use of RNAV substitution is used to replace offset DME with a zero-range indication, associated with an ILS
    • Ensure that the GNSS systems are operational
    • Comply with any limitation on RNAV substation in the AFM and manufacturer’s documentation
    • Confirm RNAV system integrity (RAIM, SBAS)
    • Review NOTAMS for equipment or procedure restrictions

 

  • In-Flight Procedures:
    • Active monitoring of system accuracy and alerts
    • Cross checking RNAV derived navigation with other instruments
    • Using RNAV for enroute navigation or approach transitions
    • Monitoring and cross-checking navigation performance
    • Managing workload and distractions

 

Error Management and Troubleshooting

  • Recognising and managing RNAV system anomalies
  • Recognising RNAV substitution errors (e.g. incorrect waypoint entry)
  • Cross-checking RNAV data with alternate navigation sources
  • Decision-making when RNAV capability is degraded
  • Awareness of workload management and human factors

 

Practical Exercises

  • Classroom Activities:
  • Briefing on the principles of RNAV substitution, terminology and presentation of approach charts
  • Briefing on limitations
  • Discuss RNAV substitutions for UK specific enroute and terminal procedures
  • Discuss RNP procedures
  • Identifying errors in waypoint programming
  • Explain the equipment available, use of GNS 650 and G5 – how to programme and access information, how to identify system integrity
  • Flight Scenarios:
    • As per FSP training modules
  • Debrief and Lessons Learned:
    • Analysis of scenarios to reinforce practical application

 

Assessment and Certification

  • Knowledge check covering RNAV substitution procedures, regulations, and limitations

Expected Outcomes

After completing this training, pilots will be able to:

    1. Understand the regulatory framework for RNAV substitution in the UK.
    2. Safely perform RNAV substitution in a variety of scenarios
    3. Monitor, Recognise and mitigate risks or limitations in RNAV substitution.
    4. Integrate RNAV substitution into overall navigation strategies.
    5. Plan and execute an RNP approach

This training ensures pilots are proficient in utilising RNAV capabilities to enhance safety, efficiency, and compliance in diverse operational environments.

 

Definitions

  • Area navigation system: A navigation system is either an RNP system or an RNAV System depending on its performance capabilities
  • RNAV Substitution: The act of using an FMS Coded Overlay procedure, selected from a navigation data base, and then executed
  • Performance-based Navigation (PBN) reliance is made on use of area navigation techniques requiring a certified airborne navigation capability
  • GNSS Global Navigation Satellite System
  • RNP Required Navigation Performance – RNP also refers to the level of performance required for a specific procedure or a specific block of airspace. An RNP of 10 means that a navigation system must be able to calculate its position to within a circle with a radius of 10 nautical miles. An RNP of 0.3 means the aircraft navigation system must be able to calculate its position to within a circle with a radius of 3/10 of a nautical mile.

No….but…..

Please bring some form of photographic ID with you. We are entering air side of an international airport as such we have to be security aware and conscious. If you do not have a passport, driving licence or other recognised identity card then please call in advance so we can make arrangements. 

If you arrive without a pre-arrangement and without ID then we may have to cancel your flight and there is only a refund of 50% in this instance, please don’t forget your ID

We do not allow high heels or shoes which could damage the wing as your try to board the aircraft.

Other than this we do not mind what you wear providing it is sensible and doesn’t interfere with the aircraft controls. (ie no big yellow chicken outfits)

We would recommend nice flat shoes or trainers especially if you would like to have a go at flying.

In the winter we would recommend typical warm winter clothing but in the summer we strongly recommend light cotton clothing because it can become hot in the cockpit before we take off.

If you are unsure give us a call to discuss.

Ok has anyone ever been sick in one of our aircraft? The answer is yes but that is extremely rare.

We have taken people flying who are known to get travel sick and they have always been ok. However; in the event of such an issue we do carry sick bags onboard which we can provide you with before the flight if you feel you might need one….. but we doubt it will be necessary!

 

Don’t be!

We take people flying who are petrified of flying all the time, in fact some people come to us to try and get over their fear.

We are trained to put you at ease from the start, if you are nervous then do mention this to our staff or your pilot before you fly.

One of the fears of flying is that you can’t see what is going on and the big planes just move without you knowing what is about to happen. In our aircraft your pilot will be talking to you all the time and they will tell you what is going on and you will be able to see it for yourself.

Don’t worry you will have an amazing experience and when you get back on the ground you will wonder what the worry was about.

Yes it is!

Flying in itself presents an elevated risk to you whether you are flying with commercial operators such as RyanAir, EasyJet, BA or in small aircraft like ours.

As we use our light aircraft for commercial operations they are also maintained to a Certificate of Airworthiness (CoA) standard by a CAA approved Aircraft Maintenance Organisation (AMO). 

Every 50 hours the aircraft are returned to the AMO for a maintenance check and oil change. Every 100 hours the aircraft are taken to the AMO for an enhanced inspection criteria, then every year there is also an annual inspection. On top of that we have time limited parts on the aircraft which must be replaced after so many hours of operations….Aircraft maintenance and inspection is the biggest expense of running aircraft!

So one thing to consider is we only have one engine on the aircraft, what happens if it fails? Firstly; it is extremely rare for an engine to fail completely in flight. Secondly in the unlikely event that it did completely fall apart and fail, then the aircraft will not fall out of the sky!  It becomes a glider and we would glide the aircraft into the nearest airfield, or into a nice long field of which we have thousands of in Norfolk and Suffolk. Our pilots are highly experienced and trained for any such eventuality.

Has it ever happened to us…. no!

NAC have parking at the front of our building. We have limited parking so we ask for only one car per flight. If you plan to arrive in multiple cars please do call ahead so we can arrange alternative parking.

Absolutely yes! 

Take your phone and take as many videos and photos as you wish.  We may ask you to ensure the phone is in flight mode but that is at the discretion of the pilot.

As a rule the answer is no. This is because the animals need to be restrained in the cockpit from interfering with the safety of the flight.

However; in certain circumstances we may allow it depending on a case by case evaluation of the request.

Please call us to discuss if you feel you have a need to bring your pet.

Absolutely –  yes please!

We want you to enjoy your experience and create memories, please share you pictures and videos with us before you leave.

We do not allow the positioning of Action Cameras and Audio recorders in the cockpit for reasons of flight safety.

 

HOWEVER: NAC do offer a professionally made video of your flight using multiple camera views and with recording cockpit intercom communications including Air Traffic control. Please discuss with us the video packages.

Limits are solely based on a persons ability to access and egress the cockpit unaided and that their size does not interfere with the cockpit controls.

However if you are concerned please call us.

The aircraft does have a weight limit, so we will ask you for your weight, please do not be offended, but do tell the truth as it is essential for flight safety that we properly calculate the aircrafts weight and balance. We reserve the right to weigh passengers prior to any flight.

We are proud to say we are welcoming of all people of all abilities. Access to our office is disabled friendly.

There are some occasions where we need to conduct a risk assessment of the likelihood and assistance needed for a disabled person to evacuate the aircraft in an emergency. 

Please do not be put off by this…. call us to discuss.

We want everyone to enjoy aviation!

Nope!

Anyone young and old can come play at NAC and enjoy the thrills of aviation.

Babies and ickle-children are welcome to come enjoy the experience, you can bring your car booster seats or car chairs for them to sit on.

You know your children best, if they want to sit in the front they are welcome to so long as they can listen to the instructions of the pilot

Unfortunately not. 

Any food or drink consumed on our aircraft must be purchased through our flight operations centre.

Unless you have a bag of skittles then we love skittles!

No.

We will provide you with a headset and high visibility vest for your experience. 

We would recommend arriving 45 minutes before your flight time. This allows you to be briefed on your flight and to take some time to relax before the experience.

Then the time of you flight you have paid for plus an additional 30 minutes for a debrief.

So for a 1 hour flight experience allow us 2 hours and 15 minutes in total

We are happy to take someone out to the aircraft parking area to get some photos of you leaving but they would need to come back to the office once you taxi out. 

We would recommend a great parking spot at each end of the runway to go and take some pictures.

At NAC we like to keep control of everything we do but the weather is one thing we cannot adjust.

We will review the weather for the days leading up to your flight, if there is anything forecast that will  cause a problem for your flight we will give you the most amount of notice possible to reschedule.  

On the day we will check the forecast continuously and update you if anything locally happens that isn’t forecast.

We will always reschedule your flight to your convenience if this happens.

These things happen!

For genuine reasons we will reschedule your flight for you free of charge. We can apply a £10 administration fee in some rare cases.

Give us a call 01603 369928 and explain why your late and your ETA, we should still be able to accommodate you.

For reasons of flight safety we do not allow you to install your own cameras in our cockpits, however we do have our approved camera systems and recording equipment we use to film your flight if you request it.

Our prices are available on the website, contact us to discuss the options.

Yes, all our merchandise is available at our flight operations centre or on our website.

Yes outside our office are the public toilets with disabled access.

We encourage you to go to the bathroom before the flight as there are no toilets on the aircraft.

Yes we do.

We offer gift cards for 1st lessons, air experiences and for account additions for regular flyers.

All gift cards are valid for 6 months.

We require you to declare any medical conditions before your flight booking.

It is rare that we would refuse a flight to you based on any medical condition but in certain exceptional circumstances we may ask for a doctors letter to say you are fit to fly.

We reserve the right to refuse a flight to anyone we believe is not fit to fly.

For reasons of flight safety we do not permit passengers onboard our aircraft who are under the influence of drink or drugs or who we believe may be intoxicated.

Should you arrive for your flight in such a condition then your flight may be refused and you would not be entitled to a refund. However; we may consider a rebooking for the future but that does incur an administration charge of £30.

If you are on medication which may affect your presentation then please let us know in advance.

This is a truly fantastic flight school. The team are incredibly friendly and the instructors are very qualified, professional, supportive, and really want to see you succeed.

I did my night rating with them, and would absolutely recommend people to choose NAC to do their flight training with. Friendly, professional, and helpful - look no further than NAC when choosing a flight school!

James Cripps

Where can I start? this flight school is absolutely incredible, the team are very friendly, very professional and extremely well qualified, and have gone absolutely up and above all of my expectations, to give my son the confidence and continued support towards his amazing journey to become the pilot he’s always dreamed of being.

I honestly can not tell you just how amazing everyone is, and I will be forever thankful for everything they have done over the past few days to help me and my son. Five stars and more highly recommended.

Thanks guys

Top flight school, very nice and friendly people. The aircraft are in great condition and the Pipers are a lot comfier for taller pilots than the Cessna's I've had at other schools. Also appreciate how open they are about pricing compared to other flight schools. 

Matthew Freeman

I’ve not flown for several years and decided to start again and explained my circumstances to Rob and he was very helpful and explained all that was required.

First flight again with Steve and now I’m thoroughly enjoying it.

Glad I decided to go with NAC.

Andy Ward

I had my first private hire from NAC this week, what a breath of fresh air!

 

The online booking facility is great, they have the best fleet of aircraft in the region and the most highly regarded instructing staff to boot!

 

The rates are very competitive with the loyalty offer and a real game changer for the industry.

 

Cant wait to fly again, Thank you NAC!

Rob Woods

The best aircraft organised by a great team.
