Sorry your question has not yet attracted a response from someone who knows the 757 better than I do. I have the type rating but did not fly it very much. Certainly not much of an authority.
However, the book says that we would typically hold V2
+ 15 knots to 1000 feet AGL, then accelerate to VREF
+ 80. We may select flaps up at VREF
+ 60 and accelerating. With more typical heavier loads we might accelerate by setting 100 fpm on the vertical speed and go through the flap retract schedule.
Flap limit speeds are 210 knots for flaps 15, 220K for flaps 5 and 240K for flaps 1.
This plane is a hotrod and MIA
the fuel load would be very light you probably would have been bumping a very high deck angle and
gaining speed approaching the flap limit speed. I doubt that they would have retracted the flaps below 1000' AGL but maybe immediately on reaching that altitude and just kept them coming up. Likely they did not have to drop the nose much to accelerate at that weight and the visual effect must have been rather like a space shuttle launch.
Yeah, it is a fun airplane.
Happiness is not seeing another trite Ste. Maarten photo all week long.
