Flight Time Vs. Air Time Personal Logbook in General Helicopter Operations Posted December 4, 2011 · Report reply Just for the record. I am not saying anybody is right or wrong. Including myself. I am merely stating my opinion and debating with those whose opinions differ. No disrespect is intended. I have no issues with logging flight time and I am not saying that there is no difference between flight time and air time. I do have issues with how "flight time" is being interpreted. "air time" - means, with respect to keeping technical records, the time from the moment an aircraft leaves the surface until it comes into contact with the surface at the next point of landing; (temps dans les airs) This is fairly cut and dry. When your skids or wheels leave the earths surface you are logging air time until they touch the earths surface again. If you were to toe in by this definition alone....you would be logging flight time and rightfully so. Although you are on the ground, you are still maneuvering the helicopter. IMHO the aircraft is still flying and should be logged as airtime. However, my opinion is different than the intent of the definition. "flight time" - means the time from the moment an aircraft first moves under its own power for the purpose of taking off until the moment it comes to rest at the end of the flight; (temps de vol) What moves under its own power? - "The aircraft" Why is it moving ? - "to take off " on skid equipped helicopter this would happen the moment the aircraft take's off. On wheeled equip helicopters this would happen the moment they start to ground taxi for the purpose of taking off. When does it end? - When the helicopter comes to a rest at the end of the flight. What is the definition of flight???? If you fly from point A to point point B Land and shut down. Does your flight time not end the moment the aircraft lands and is safely on the ground. Because you "choose" to keep the aircraft running because you are "intending" to do "another flight" should not be logged as flight time. Your initial flight is finished. You have reached your destination and have landed safely. The helicopter has come to a rest. You could shut it down and unload or you could keep it running and unload. If you were toed in then yes this would be flight time in line with the definitions. The air craft is touching the surface so it is no longer air time. The helicopter has not come to rest. If you were to turn the engine off the aircraft would disastrously come to its own "rest" First skids up after start to last skids down before shut down is flight time. And that is correct! (At least how I interpret it.) At the schools I have worked, we have added 0.1 to the total air time to obtain FLIGHT TIME, and don't find that completely unfair, as you can spend 20 minutes or more on the ground. The hobbs meter in most of those machines ONLY run in the air to get AIRTIME. Cheers H. I think this is more than fair. However, If flight time is calculated from first skids up after start to last skids down before shut down, then this flight could easily be logged as a 1.4 or more and here lies the problem. Freewheel..... I commend you on your obviously repeated attempts at clarification and yes, you have definitely identified a problem. I will also be filing a report.
