So what counts as real flying hours :- The stuff that you log in your logbooks?
From 14 CFR § 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.
Until now i've been logging whatever the Hobbs meter showed me. However, I've noticed that on the C172's that i fly, the tach does not run when the engine is idling and that the Hobbs doesn't run when the RPM's are below 1000. Now when taxing the engine RPM's are below 1000 and so the Hobbs doesn't run but the Tach is running and thus counting airframe/engine hours.
I'm glad sometimes that i've to pay for the rental by the Hobbs since it doesn't count the startup checklist and taxi up and down time (sometimes taking up to 20+ min), but also that those hours will not count for my logs since the Hobbs doesn't log the time when engine is running lower than 1000 rpm
So how do you guys really count time? Hobbs? Tach? or Stop watch from start to end of flight?
Regarding the same topic i only found this:
Hobbs Vs. Tach? (by Shaun3000 Aug 6 2002 in Tech Ops)
discussing differences between tach time and hobbs time but no info on time you actually log.
