A350 V2+10 climb performance single engine

Does the flight director on the A350 command pitch for single engine during a failure on take off? At MTOW, the aircraft is unable to climb. Single engine at lower weights (near MLW) is fine

this is for all planes

At which airport are you taking off from?

Are you using TOGA thrust for takeoff?

Doha (10ft elevation), calculated flex take off, TOGA is set after V1, Once the engine fails (At MTOW) aircraft will not climb. Lower weights are fine single-engine.

The aircraft should be able to climb with a take-off derate, even with FLX/MCT being the thrust limitation for Vmcg/Vmca.

Ah, I overlooked that you had one engine inoperative. Yes, that is a known issue with the current engines. The thrust drops too much from static to around 200kt. It should remain somewhat constant but I have no real world data to rely on.
