Desert185,
Don't discount the fact that the autopilot is still available with a loss of IAS. There is a selected Pitch Damp mode that the pilot can select to maintain attitude if desired. Options are nice.
We had APs with pitch wheels a bit like that on the B707 and other types of the 1960s and 70s, used to select pitch in climb and descent, plus a "height" (ALT) lock. Not sure if the ALT lock tripped with loss of IAS - probably not. On Airbus FBW, tripping the AP is normally a non-event, because the FBW effectively holds the current attitude at least as well (initially).
bubbers44,
Are you saying the Tristar airbrakes do not retract themselves automatically after the aoverspeed? And does the lever move to reflect their extension?
