OK - seconds out - round 2

Zorin Roll control is direct law, stick position -> surface position.

Gums roll commands do not command a 1 for 1 deflection of either the spoilers or ailerons in Alt1 or Alt 2, only in "direct law". That's what my copy of the FCOM shows. The commands except in "direct" are roll rates, and the "gains" are set by various inputs and other control surface settings. So no direct deflection of surfaces according SS deflection.

Which FCOM/understanding is correct? It could be important in a confused cockpit. Not a lot of time to open an FCOM volume? Let's get it right?

Ding Ding Ding.

Oh yes- a round is 3 minutes I think - about the time from 38,000 to sea level at a high rate of descent .
