Either terrain or obstacles can trigger FLTA alerts and they are
distinguished via the CAS messaging and aural alerting. The
difference between FLTA warnings and cautions is exclusively
based on distance-to-go to projected impact points or reduced
clearance areas.
The reduced terrain and obstacle clearance distance varies with
phase of flight and aircraft dynamics per TSO C-151c but
generally ranges from 300’ to 1000’.
SynVis terrain awareness indications do not product CAS
messages or aural alerts but SynVis FLTA alerts do.
