Re: Which fAR Part?

Read thru it, it should be pretty self-explanatory. You might go the FAA (or EASA) TCDS listing for a overview of the format, but for specifics, you might need to have enough engineering background to understand FAR 23 certification.

Yes, but the one tank (actually one in each wing) would have to be filled on the ground some number of times, that number depending on which model you speak of. Also, depends on where you started and where you wish your destination to be. Specifics are needed
