A330 automatic pitch trim after engine start


AVFC

Recommended Posts

Hello Aerosoft,

A330 pitch trim is now automatically set to THS value on MCDU PERF TAKEOFF page after second engine start.

Is this a new feature to reduce crew work load (and possible crew errors)?

 

P3D v 4.5

A330 v 1.0.4.2

Thank you for clarification. To be honest, there is not much information on this in the A330 documentation.

A Step-by-step guide on the A330 would be nice.

Error in documents....should be check in the A330.

FCOM:

NORMAL LAW PITCH:


Ground mode is active on ground. It is a direct relationship between sidestick deflection and elevator
deflection without auto trim.
The THS is automatically set at 4 ° UP (inside the green band). Before departure, as soon as the
three hydraulic systems are available, the THS is automatically set to the takeoff value, calculated
by the PRIM, according to the ZFWCG entered in the MCDU and the fuel distribution. This automatic
setting occurs only one time, and the flight crew can override it at any time.
The rotation maneuver is flown in direct law, with full authority.
Immediately after the aircraft becomes airborne, the flight mode is progressively blended in. The
reverse process occurs after touchdown.


NORMAL PROCEDURES - AFTER START:


PITCH TRIM...........................................................................................................................CHECK
Check the takeoff CG on the PITCH TRIM handwheel using the ECAM’s CG indication.
