FTL
Gentle rotation has always been the answer to most take off problems, get V2 ++ under your belt before commiting aviation. Then a engine failure is a piece of cake, and the margin between the stall of a contaminated wing (singular) is below the flying speed.
As an aside, but still related: Many times I have been over 14hrs, if you look at realistic pre flight duty times and post flight duties, Since when has the trip from the hotel, been included in these calculations.....Also many times sat on the ground in Moscow, or similar cold locations, and waited for deicing, Then depted on a 12hour + flight....All perfecly normal for a Corporate driver. Three Charters in the last week.............And the company insisted the aircraft then ferried back to base, to save a hotel night.
Please do not think that Corportate charter operators actually comply with FTL, and when the real "duty Time" is considered, almost all Gulfstream V and G550 flights are scheduled in to discretion.
Please prove me wrong, by quoting the times your CAA have punished an operator.
Then you are scheduled for Minimum rest...in day time, after waiting for the cabin crew to finish, then the hours drive to the hotel, and then the delays with a morning check in. 20 hoours of real ON DUTY TIME, and 10 hoours rest.
De icing once or even twice is a common need in the RF, and the quality is slightly dubious.
