What a load of B*llocks!
Off blocks to On blocks = flight time 1hr 10mins - what about the 20 min taxi and time spent hanging around at the holding point whilst Air Tragic sort out your clearance?
Flight time is from rotation to touchdown for a full stop landing, rounded up or down to the nearest 5 mins
As an aside, I always tried to impress my students when they asked how many hours I had ammassed
"15,000" I replied
"Wow, that's amazing"
"Yes", I said "8,000 on type, 7,000 waiting for MT"
