Today when i go to fly from HAAB to OMDB the take of calculation give me take off settings some make me run out of runway before i reache V1.

Estimated TOW was: 211,713 kg

Take off performence used 215,000kg to add some extra safty margin with Take off.

The onboard TO Perf calculation give me this:

Flaps 2

Flex 67

v1:163

vr:164

v2:169

RW25L TODA: 3803M.

I have noticed that Flex 67 is given to me at ewery flight i do with the A350. That make non sens at all. Tempratur, QNH, TOW, RV attidue will allways afect the Flex temp, but not in this case.

When i run take off performence on simbreef i got totaly difrent result.

Flaps: 3

TOGA

v1: 131

vr: 131

v2: 139
