B737 TOGA Party

Shockingly tedious post no 2 I'm afraid, however does anyone know where it is written that the take off performance for a B737 300-500 assumes that TOGA is pressed within 2 seconds of the engines stabilising at approximately 40%.

I seem to remember it (GECAT ?), but cannot find it in the company manuals.

Thanks in advance,

MoT

Hi MoT

My copy of the 737NG Flight Crew Training Manual has the following note on p3.4:

Allowing the engines to stabilize provides uniform engine acceleration to takeoff thrust and minimizes directional control problems. This is particularly important if crosswinds exist or the runway surface is slippery. The exact initial setting is not as important as setting symmetrical thrust. If thrust is to be set manually, smoothly advance thrust levers toward takeoff thrust.

Note: Allowing the engines to stabilize for more than approximately 2 seconds before advancing thrust levers to takeoff thrust may adversely affect takeoff distance.
I no longer have access to a 'Classic' FCTM, but I assume a similar statement will be included.

I hope that helps.
