IFD500 Series Pilot Guide
4-64 Map Subsystem
FLTA Off – the FLTA function is disabled (which effectively
disables the terrain alerting function)
Note that regardless of the LSK selection, the altitude callouts
function remains enabled (subject to configuration and setup
options).
SELF-TEST
When the TAWS option is enabled (TAWS-B or HTAWS), and the
aircraft is not airborne, a “Self-Test” LSK is shown on the page.
Press the LSK to manually initiate the same self-test procedure that
is performed on power up (see page 4-53). While the self-test is in-
progress, the Map SVS view will show the message “TAWS Self-Test
In Progress”.
