Thanks, Peter. I appreciate the time, and effort that must have taken.
The fact remains though, that nothing there excludes the possibility that flight time as a passenger is included within the term 'flight time'.
AMC1 FCL.050 Recording of flight time
(a) The record of the flights flown should contain at least the following information:
(1) [..]
(2) [..]
(3) [..]
(4) details on pilot function, namely PIC, including solo, SPIC and PICUS time, co-pilot, dual, FI or FE;
Unless, on closer examination, we can take this as a de facto definition of the term 'flight time'?
