puntosaurus: For example in EASA land there is nothing wrong with you handling a machine on a private flight under the supervision of an appropriately qualified commander.
Oh! So me, a piston rated PPL(H) may legally act as pilot flying some nice turbine heli,
as long as the (CPL) sitting in the PIC's seat is a qualified commander,
say, when "ferrying" the ac back, after the paying customer had exited?
In EASA land??
Does that include takoffs and landings?
Does he have to be a FI for that type?
