Could it be due to noise abatement procedures? Just curious..
|Quoting 777way (Reply 6):|
As for sound I have seen PIA 777s fly out so silently after take off that if they hadnt caught your eye you wouldnt know they were around and this is like maybe two minutes after take off, what causes the engines to not make any sounds?
|Quoting 76er (Reply 5):|
Normal procedure at AMS is the NADP1 for all aircraft. Meaning takoff thrust (full or derated) until 1500ft, followed by climb thrust. Speed between approx V2+10 up to V2+25 till 3000ft, then accelleration to 250kts or higher as dictated by either local regulations or aircraft performance.
Most aircraft will takeoff with the maximum allowable thrust reduction on takeoff, for reduced engine wear. For mechanical or weather reasons it may happen that full thrust is required for takeoff, which may be an explanation for the very short takeoff roll and steep initial climb.

The weather plays a large part in how long a take off run is needed. The head winds, the temperature, the humidity and event the barometric pressure can have an effect on the aircraft's runway length.

an A380 requires 20% less runway than say a B744
