Ground tests & pilot logbook.
Just a curious question here. Normally when I fly, my pilot logbook
time starts when the hobbs meter starts ticking. That includes probably 10 minutes of taxing, runnup, etc. What about taxing tests on a experimental? Does that count? |

In military you started your time as you started your takeoff roll. You continued to log time until engine shut down in parking area. Guess they thought that if you had to hold for take off it shouldn't count and after landing there was not much traffic taxing to bump your time. In GA I logged the Hobbs. Lets see what other people do. Big John On 9 Feb 2004 20:47:53 -0800, (Paul Lee) wrote: Just a curious question here.

Ground tests in and of themselves should be logged in the _airplane_ record (I recorded time from startup to shutdown) but not in the pilot's log. From CFR 14 Part 1.1, definitions: 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; ... It's that 'purpose of flight' thing that gets you. Dave 'iced in' Hyde |

IIRC, you're supposed to log from the point "the aircraft first takes movement for flight." If the purpose of the engine start is something other than flight, you don't log it. I think counting the time on the Hobbs meter comes from the way you pay for aircraft rental... most places charge for the time on the meter, so you might as well log it. If it's your own aircraft, your maintenance schedule probably runs off the Hobbs meter, so you're still paying for that time. Of course Ron, you're right, the .1 or .2 between startup and taking the runway technically aren't supposed to be logged. If one is taxi testing and inadvertently take wing, well, you can legally log that hop- I think you're actually supposed to. Also, I'm pretty sure I got air under all four of my car tires (at the same time) once or twice a lot time ago, but that's a logbook entry better left out... |

If you're taxiing out in order to intentionally fly it sure is loggable as flight time. I posted the FAA's definition of flight time elsewhere in the thread. As for how to measure logged time, I don't have a Hobbs or a reliable recording tach in the cockpit. I use 'wris****ch' time. Dave 'not P-51 time' Hyde |

Those of you in Northwest Ohio, and many of the other flat states, are familiar with the "humps" that all of the railroad tracks are on. For those of you that are not, they are about the greatest jump ramps made. Some are even fantastic. Most front engine cars will jump, and land *very* front heavy. Ask a friend of mine, how that hole got in the oil pan of his parent's caddy. g I had a Corvair. They jump very nicely. I regularly cleared a whole second of airtime, and perhaps a bit more. After I bought my new car, my brother got the Corvair. It died of tin worm, and from the front unibody allowing the tops of the tires to be closer together than the bottoms.. not good. I later found my brother had made the track jumping into a whole new art form.... -- Jim in NC --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

If it's your own aircraft, your maintenance schedule probably runs off the Hobbs meter, so you're still paying for that time. Actually, I believe maintenance schedules are usually driven by tach time. I got a hobbs meter in my plane, but I'm gonna chuck the thing one of these days. Never look at it. Of course Ron, you're right, the .1 or .2 between startup and taking the runway technically aren't supposed to be logged. Thanks, but I apparently wasn't clear: If the purpose of the engine start is to take the airplane to the runway, I feel the time should be logged as flight time. Ditto for the taxi back to the tiedown/hangar after landing. If you stop at the gas pumps on the way, you *don't* log the time from the pumps to the hangar...the purpose of the movement was not flight. Years ago, I pointed out this philosophy had an interesting loophole: I could log "flight time" when I was *not* in the airplane. Y'see, the club Fly Baby didn't have a starter, hence I had to hand-prop it. When the engine started, the thrust would pull the airplane slightly forward, onto the chocks or the limit of the tiedown rope. The airplane "was taking movement for flight," though there wasn't anyone in the cockpit. And don't forget: The flight isn't over 'till the wheels are chocked. Can't do THAT from the cockpit, either. :-) Ron Wanttaja |

However, you cannot believe how pricey and elaborate some doods can get in the name of flying.... even with a wris****ch. Barnyard BOb - anybody seen my $9.99 Timex? |
