If radio-altimeter is set to 100m (10:10:07,2; 10:10:10,6) and flying in auto-pilot mode (FMS, Universal Avionics UNS-1D), can it go below 100m without switching to manual mode?
Tu-154M autopilot is the ABSU-154-2. No public information how/if it was somehow interconnected with UNS.
When reaching 100m should radio-altimeter activate some kind of audio alert?
RA set later to 60 m.
