I finally managed to find a current (I think...) version of Part-FCL. Could someone clarify the following extract?
FCL.135.A LAPL(A) — Extension of privileges to another class or variant of aeroplane
(a) The privileges of an LAPL(A) shall be limited to the class and variant of aeroplanes or TMG in which the skill test was taken. This limitation may be removed when the pilot has completed in another class the requirements below:
(1) 3 hours of flight instruction, including: (i) 10 dual take-offs and landings; and
(ii) 10 supervised solo take-offs and landings.
What is meant by "class and variant" of aeroplane? Does that mean that if I wanted to convert from a Cessna 152 to a PA28 (for example) I'd need to do 3 hours instruction and 20 takeoffs and landings? What about C152 to C172? Or would that only apply for differences training, such as fixed to wobbly prop?
