This is a simple question.....on what guidelines or by whose rules are the times for turnarounds determinded in order to keep FDP's honest?
Did you bother to read post #12? What was missing in that?
Now, "sign off 30 minutes after in order to keep the PLANNED FDP" has no relevance for FDP That is based either on chox or chox + 10 normally.
The 'Ryanair' you quote would, I suspect, be flagged early by either the union or pilots themselves as impractical, with regulatory oversight. Again, read post #12.
none of this is relevant but I want to know on what do I base the turnaround times if I am the operator and I want the flight to be planned legally?
- you appear not to understand. ALL of that 'is relevant' in terms of how long you would need to plan.
In the 'Global one on one off' case I would suggest 5 minutes would be acceptable - 1 engine running?
There is no 'legal minimum' I am aware of since every operation/sector will be different. Going to tell us any more? Believe me, we are all trying to help!
Start by telling us a bit about YOU - pilot/crewing/ops/what?
