Citation X rating
Does the FAA allow a co-pilot with an ALTP rating with an aircraft type of over 20,000lbs on his licence, to act as a SIC after attending FSI initial course on a CE750 without getting the type rating on his license. Then fly on a Part 91 or Part 135. Flight operations would be in the USA and Europe. This way he could build experience before getting a captaincy and rating on his next FSI ride... no clear answers from the FAA
