Heavens above! What next?
What is the definition of "flight time"
If you don't know then look it up!
I'll give you a clue - something to do with "Brakes off with the intention of taking off" Which would include taxi out, mag checks, fail mag checks, taxi back and park. (after all, you've exercised all the Captaincy required during that time? to "Brakes on at the completion of the flight"
In other words brakes on to off.
Nothing says what units it is recorded in either. What is the difference between time recorded to the nearest 5 or 6 minures or even the nearest 3 seconds?
Nothing!
- as long as there are enough flights for the numbers to average out, which even over the period of a first solo they would, let alone a PPL, let alone even a CPL
Logbook time is brakes on - off outside the clubhouse, or on/off stand when you're in a 737. No difference.
