You can certainly use block time, but you will unnecessarily increase your cost of maintenance. Time in the air/"tach time"/G1000 Time in Service is the standard by which aircraft are normally maintained. It's what Diamond uses, and it's what all mechanics here in the US use.astaib wrote:It seems that you are right for block off/block on (when the aircraft is moving by itself), but the airborne time can be used only if this is written in the AMM.

Re: Flight time in the Aircraft log-Book
The AMM uses the term "Flight hours" in the maintenance instructions. See, e.g., Chapter 05-20-00, paragraph 1 -- "Do the scheduled maintenance checks at the intervals (flight hours and calendar time) stated in Section 05-10, Paragraph 3."

Re: Flight time in the Aircraft log-Book
Hello,
in EASA Countries:
- Aircraft time for maintenance ist time only in the air (Take-off to Landing).
- For your flighttime (Logbook) Block-off to Block-on. This is the time for your ratings ...
Greetings Oliver

Re: Flight time in the Aircraft log-Book
Servus Oliver,
I’m surprised to read what you have wrote because the head of French general aviation said to me that the basis of EASA is bloc off / bloc on. And if and only if the AMM specify that the airborne time can be consider it is possible to use it instead of bloc.
Do you know where this information is available at EASA?
Thanks.
Arnaud.

Re: Flight time in the Aircraft log-Book
I know that the Canadian Air Regulations (CARS) bases aircraft time on Air Time (time up to time down) CAR Standard 625.93

Re: Flight time in the Aircraft log-Book
For N-reg aircraft, this should be based on the definition of "time in service" in 14 CFR 1.1:
Time in service, with respect to maintenance time records, means the time from the moment an aircraft leaves the surface of the earth until it touches it at the next point of landing.

OMG, OMG, we're all screwed There is no instrument that measures this. The VM1000 records run-up time and the ground run time before the wheels lift off. And ignores pretty much the entire descent to landing in a normal pattern.

Sorry, but I didn’t get it.
Maybe because I am French ?

Re: Flight time in the Aircraft log-Book
I've just watched the hair-splitting with amusement, is all. In the US, tach time has been used as the basis for hour-based maintenance intervals for almost all planes. And there are all sorts of variations on this, none of which amounts to the section quoted by Wolfgang. (Not a criticism of you, Wolfgang, just noting that the FAR you cite is almost universally ignored and impractical.)astaib wrote:Sorry, but I didn’t get it.

For example, legacy mechanical tachs (by far the most common) track engine revolutions, converted to time based on a fixed calibration. So time ticks along as soon as you start the engine and continues to log time as long as the engine is turning. For idle and taxi, of course, it runs substantially slower than actual time. In flight it might run faster or slower than real time, depending on engine RPM. So its relationship to "time in service" per the reg. is nebulous, at best.
