What are the differences between the CPL and the MPL?
For the purposes of operating multi-crew aircraft, the privileges of a MPL are equivalent to those of CPL endorsed with an instrument rating and a type rating on a multi-crew aircraft. However, and because the MPL is geared toward operation of multi-crew airplane, an MPL pilot cannot generally fly on single pilot aeroplane without meeting additional requirements. For example, MPL holders cannot exercise the privileges of a CPL and instrument ratings on single pilot aeroplane without meeting specific actual flight time and flight instruction requirements. A number of MPL courses may be a modification of the current JAA frozen ATPL or the Transport Canada and FAA CPL/Multi-engine training, but it is expected that the majority will follow the guidance proposed in the Procedures for Air Navigation Services — Training (PANS-TRG) document.
