Yes, Martin, I also gathered that from the cockpit and flight controls layout available in the public domain.

takata, I'll suggest to you that pilots know that because that is part of flying.
The mental and congnitive process, when you are doing this on instruments (which I presume AF 447 crew were, as it was night and the Wx was bad) is to set an attitude in balanced flight and trim to hold that attitude in all three axes. (Plural of axis)
What I was taught and used to teach was to trim nose and rudder first, aileron last, to avoid cross trimming, but such technique is probably model dependent.
