AUTOMATIC CALL OUT
FWC generates synthetic voice for radio height announcement below 2500 feet. These announcements come through the cockpit loudspeakers even if the speakers are turned off.
PREDETERMINED CALL OUTS:-
callout:-
2500 "TWO THOUSAND FIVE HUNDRED"
500 "FIVE HUNDRED"
40 "FORTY"
20 "TWENTY"
10 "TEN"
DH (or MDA/MDH) + 100 "HUNDRED ABOVE"
DH (or MDA/MDH) "MINIMUM"
Note : The reference altitude for the +100 and Minimum call outs is the radio altitude for precision approaches (DH) and baro altitude (MDA/MDH) for non precision approaches.
Pin programming allows the operator to select the callouts needed. If aircraft remains at a height that is in the detection zone for a height callout, the corresponding message is repeated at regular intervals.
