This fixes the condition (always indicated when the autopilot comes off), but it does not fix the sound and warning. We need a separate warning light for this that will flash master warning, but only temporarily and will not play the cricket sound, only the cavalry charge. This fixes the condition for #5, but not the presentation.

The
AP 1+2 OFFmessage + master caution keeps coming up in situations where I don't think it should. When I looked at the condition, it says when autopilot is off and:Doing a visual approach almost always falls in 2. But sometimes such approach is stepped, in which case the condition is intermittent and each time the plane starts to descend, the master caution lights again and the ‘cavalry charge’ chime sound again.
What reference are the conditions based on?
As far as I can tell, it is supposed to sound exactly once whenever autopilot comes off for whatever reason (including during autoland roll-out below 70 knots). It also seems to be supposed to flash master warning (not caution) and clear it automatically.
