Warning: This is a long post. I have tried to use correct spelling & grammar to at least make it bearable. Hopefully people smarter than me can help me figure out some questions/scenarios. I have done my research, but maybe I am just looking in the wrong place. Thank you in advance. To get a commercial certificate, part 61.129 mentions "...must log at least 250 hours of flight time as a pilot..." To get an airline transport pilot certificate, part 61.159 mentions "...must have at least 1,500 hours of total time as a pilot..." What is considered "flight time as a pilot" and "total time as a pilot"? From part 1.1: Flight time means: (1) Pilot time that commences when an aircraft moves under its own power for the purpose of flight and ends when the aircraft comes to rest after landing; or (2) For a glider without self-launch capability, pilot time that commences when the glider is towed for the purpose of flight and ends when the glider comes to rest after landing. So, I found the definition for pilot time. From part 61.1: Pilot time means that time in which a person— (i) Serves as a required pilot flight crewmember; (ii) Receives training from an authorized instructor in an aircraft, flight simulator, or flight training device; or (iii) Gives training as an authorized instructor in an aircraft, flight simulator, or flight training device. Surprisingly enough, with all the definitions provided in 1.1 and 61.1, there is not a definition for "pilot". Just "pilot-in-command". Scenario #1: My friend and I buy a Mooney to get our commercial certificates. We hire an instructor and we fly to Florida (from Texas). I am in the front on the way there, and I am in the back on the return trip. Obviously, I can't count being in the back seat as PIC, X-C, etc. However, can I count it towards my 250 hours? Flight time requirement is met due to the aircraft moving under it's own power with the intention of flight. Pilot time requirement is met due to paying attention to the instructor in front who is giving instruction (61.1(ii)). Scenario #2: I am now working towards my ATP. I get a job as a contract pilot being in the right seat of a King Air (insurance requirement for the charter company). I know I cannot log PIC, X-C, nor even SIC, because I am not a required crew member. However, I am a commercial multi rated pilot sitting at a pilot station. Does this count towards my 1,500 hours? Note: This does NOT say "flight time as a pilot", it says "total time as a pilot", which is not defined in the regulations. Scenario #3 (and this is way out there): I am now type rated in Boeing 737, and I am commuting in the economy class cabin. Does this count for total time? I almost didn't put this scenario in because it lacks common sense...however, you made it this far into my post, might as well push the envelope. Thank you for your responses, and thank you for spending half an hour reading my post.
