Maybe I am not being clear, I have no intention of misleading or being devious. I am after information.
To pose it another way.
Lets presume I am an operator and I want to do a charter.
This flight has 5 sectors, the total flying time is 9 hours 30 minutes with a departure time of 08h45. How can I get this flight to fall within an 11 hour FDP.
The FDP starts at 07h45. By 18h45 my crew must have signed off. (11hours after sign on) with 9h 30 flying time and 4 turnarounds I cannot afford to plan for 30 minute turnarounds. what prevents me from planning 15 minute turnarounds even though I know they will not be achieved?
I cant make it clearer than that.
