And another one: if somebody wants to take a ride in a brand new Cessna Skyhawk JT-A under EASA license, does this means the need for EFIS, VP and SLPC endorsements, as it is a G1000 equipped Diesel aircraft with Single Lever control?
I don't think you'd need a separate VP signoff if you fly an SLPC aircraft. In fact, one could argue that training in an SLPC aircraft does nothing to prepare you for flying in a VP/CS aircraft.
At my club most of the ab-initio training now takes place at SLPC aircraft (Robin Ecoflyers). We need transition training if a pilot wants to convert to an aircraft with a fixed pitch propellor + manual mixture + manual carb heat.
