Hi Machinbird,
Is direct law also done with pulses, or is it a continuous input?
In ALT Law, it has to be flown like any conventional aircraft in roll. The control input has to be held against any roll tendency until the load is trimmed out. Since there is no aileron trim, you have to use rudder in order to be stick free. It would appear that PF was attempting to fly the aircraft using large pulses when he was in roll direct.
(I have to assume that Alt2 Law experience with mixed control modes is very unusual/scarce.)
Most of my ALT LAW practice in the sim was at low level.
