NTC 03/09 Differences Training Resource

The LAA website states: 

"Tailwheel / VP Prop / Retractable Undercarriage / Turbo and Supercharging / Pressurisation 

Under JAR, you are now required to complete differences training with an instructor and obtain the relevant signature for conversion onto aircraft with: tailwheel, variable pitch propellers or retractable undercarriage, turbocharged or supercharged engines or pressurised cabins. You can complete this training with the Pilot Coaching Scheme." 

Additionally, use of EFIS requires differences training, and NPPL holders require differences training for aircraft with a cruise speed in excess of 140 knots. 

PCS Differences training 
Details of differences training are contained in LASORS Section F, under Genereal Information. LASORS Section F, Appendix E contains "Guidance on Differences Training" for variable pitch propellers, retractable undercarriage, turbo/supercharged engines, cabin pressurisation and oxygen systems, and also tailwheel. Differences training requires an entry in the student's logbook and signature from the instructor/coach upon completion of training. Stickers are provided to instructors by the CAA to assist in completing the logbook entry. 

Coaching fees for differences training are listed as £75. This consists of £25 to the LAA and £50 expenses for the LAA Coach. Since the amount of training is going to depend on the previous experience and ability of the student, it is expected that the coach assess when this reasonable expense is exceeded, and arrive at a mutually agreeable arrangement with the student. 

The coach is responsible for assessing aircraft airworthiness and insurance coverage, and must forward details of training completed together with LAA collected monies to LAA Head Office upon completion of coaching. A training record is available from LAA Head Office for completion by the coach, and will be available for coaches to download shortly. 

Tailwheel training 
Tailwheel training is the exception to this, since it is generally accepted that this takes more time to complete. The LAA member should apply to LAA Head Office with forms downloaded from the LAA website with a copy of their insurance and £150, of which £100 is paid to the coach upon completion of training and £50 to the LAA. It is expected that this sum covers approximately five hours of flight training. 

As detailled in your PCS Coaching Manual, if training take significantly longer, the coach is expected to reach a mutually agreeable arrangement for payment of expenses for further training. It is left to the discretion of the coach, since there will be a number of variables such as travelling distance, number of hours or days spent training, subsistence requirements and so on. I know there are a number of coaches, like myself, who do not charge for coaching, but the LAA fee must be returned. 

In order to cover LAA Coaches for liability, personal accident and injury insurance, the LAA pays a significant sum of money, which depends upon returns from coaching activities to meet the balance. 

To summarise: 

Differences training required under JAR 

Tailwheel / VP Prop / Retractable Undercarriage / Turbo and Supercharging / Pressurisation / EFIS 


Differences training required under NPPL 

Tailwheel / VP Prop / Retractable Undercarriage / Turbo and Supercharging / Pressurisation / EFIS / 140 KNOTS 


Chargeable at £75 (£50 coach / £25 LAA) except tailwheel conversion which is £150 (£100 coach / £50 LAA).
