Stalling during takeoff

For Heavies such as 787 and 777, regardless of which version. For all types of 7878 and 777, I typically as I do long Hauls and the flight is heavy, I need lift at the around 150-170kts so I don’t overshoot the RWY, therefore I set my flaps for those Aircraft at 15° with a V/S between 800-1200ft. After a few seconds, as I gather speed, I begin to tilt the plane a bit further back to so my V/S is around 1800-2200ft. From there I adjust the speed and V/S to certain Altitude before engaging the autopilot.

I do use flaps at 5° when the aircraft is very light. A flight with Qatar Airways 777-300ER from Phnom Penh to Ho Chi Minh City, is where I’d use flaps at 5° sue to the light weight of the aircraft, but I could also opt for 15°, to ascend quicker. It comes down to the weight of the aircraft. Got a lot of Passengers and Cargo, then 15° is still a better option.

Also try to use a negative Trim, that could potentially help/save you from not stall if you happen to pull back too much or gather to much lift due to a too high flap setting, which could result in the plane pitching up too high.

Now, I personally, last year, two times faced this issue, where I had flap setting on a 777-300ER at 20°, which caused the plane to pitch up more than usual. I had to force the plane’s nose down, so since then I studied in how 777 and 787 as well as other Heavies have their flap setting depending on weight, runway length and other factors, such as weather. So for now, I rarely use 20° flaps on any aircraft whatsoever. 15° goes my limit usually, even last night I took of with very heavy 777-300ER from SFO to HKG, for a 14h 30min flight with 15° flaps and had no issues taking off, and now the same flight with little less weight but still 15° flaps took off from HKG and on its way to SIN.

You could go to Solo Mode or to the Casual Server and ty out different flap setting and Trim settings with various different weight and weather distributions and see what works and what does not.
