Hobbs/VDO, tach time and airswitch?
I (think that I) know the difference between these two times however when referring an aircraft to a 50 or 100 hourly maintenance, which time should be considered? Hobbs or tach?
Same question regarding overhauls. If your aircraft manufacturer states TBO: 2000 hours, is that in Hobbs or in tach time?
Also:
– It would seem that in Australia the Hobbs meter is usually called VDO. Is that correct?
– Is the tach time the same as an airswitch?
