HT
AWS Controls
The HTAWS function has control options on the HTAWS Page using the MENU key.
The options are activated by highlighting the desired option and pressing ENTER.
The "Inhibit HTA WS?" menu selection is used to inhibit HT AWS alerts. When alerting
is inhibited, all HTA WS aural and visual alerting is suppressed. HT AWS should be only
inhibited when in visual contact with terrain and when the pilot can be assured of
maintaining clearance from terrain and obstacles. Use the "Enable HTA WS?" to un-
inhibit the unit.
The "Mute Active Caution?" menu selection is used to mute an HTA WS caution that is
presently active.
When the caution is resolved, the next caution will be heard. It does not
mute warnings, only cautions. The "Unrnute Active Caution?" is used to cancel the
mute. An optional "MUTE" external switch installation on the cyclic stick is allowed to
mute the caution that is presently active in the same manner as using the Page Menu
selection.
The "Reduce Protection?" menu selection is used to activate the Reduce Protection (RP)
functionality.
RP Mode reduces alerting thresholds and suppresses aural and visual
cautions to allow operation in closer proximity to terrain and obstacles while continuing
to provide protection from terrain and obstacles. The "Enable Full Protection?" menu
selection
is used to select full protection functionality again. An optional "RP MODE"
external switch installation on the cyclic stick is allowed to toggle Reduce Protection and
Enable Full Protection in the same manner as using the Page Menu selection.
The "Test HTA WS?" menu selection is used to activate a manual test which verifies
proper operation
of the
aural and visual annunciations
of the
system. The aural message
"HTA WS System Test, OK" is played if the system passes the test, if the system fails the
test "HTA WS System Failure" is played. HTA WS test is only available while on the
ground.
Yoice callouts (yeas)
provide voice annunciation
of the
aircraft height above terrain
when that threshold is crossed. VCOs may be enabled by the pilot in 100ft increments
from 500 feet above ground level to the surface. Enabling yeas
is accomplished using
Voice Callout selection in the AUX pages.
