We set TOGA initially, I always figured it was because, if you are wanting to climb away from the ground, why use reduced power on the good engine when you can have full power?
We may maintain TOGA for 10 minutes if necessary.
We don't do anything below 400 feet radio, apart from going TOGA if its an engine problem, raising the gear if appropriate, cancelling all the noises and engaging the autopilot if we can. Then its the initial ECAM actions and also we may have an emergency turn (company thing).
At acceleration altitude we go V/S zero and retract flaps/slats. Once clean, and at green dot we go "expedite climb", reduce to MCT and then climb up to MSA at green dot speed.
Jtr, what's the problem with going to TOGA and then later back to MCT?
Is there a reason why your company chooses not to use all the power available? Is it what Airbus now recommend? Do they recommend it for the A330 and why?
Interesting...
