Hi takata,
There is a beautiful aircraft waiting to come out once the Normal & Alt Laws have been removed.
From FCTM
Direct Law
In most triple failure cases, direct law triggers.
When this occurs:
• Elevator deflection is proportional to stick deflection. Maximum deflection depends on the configuration and on the CG
• Aileron and spoiler deflections are proportional to stick deflection, but vary with the aircraft configuration
• Pitch trim is commanded manually
Handling characteristics are natural, of high-quality aircraft, almost independent of the configuration and of the CG. Therefore, the aircraft obviously has no protections, no automatic pitch trim, but overspeed or stall warnings.
OPERATIONAL RECOMMENDATION:
The PF must avoid performing large thrust changes, or sudden speedbrake movements, particularly if the center of gravity is aft. If the speedbrakes are out, and the aircraft has been re-trimmed, the PF must gently retract the speedbrakes, to give time to retrim, and thereby avoid a large, nose-down trim change.
