IFD400 Series Pilot Guide
Map Subsystem 3-47
Map TAWS Tab with LSKs
The LSK provides three selections:

On
– the full HTAWS capability is enabled

RP Mode
– the HTAWS function is operating in “reduced
protection” mode, where protection limits are reduced to
prevent nuisance alerts.

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 HTAWS is enabled 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 3-42). While the self-test is in-progress, the Map SVS view will
show the message “TAWS Self-Test In Progress”.
