ST3400H PILOT’S GUIDE
Page 4-2
(relative altitude) terrain display is automatically selected at an appropriate
range to put the alerting terrain on-screen.
Pilots should train to react properly to all alerts, cautions and warnings, just
as one would train to react to any other potential or actual emergency
situation.
Pilot reactions to alerts and warnings differ according to weather
conditions, visibility, types of warning, phase of flight and aircraft
performance considerations. Pilots should be thoroughly familiar with
FAA, company, or other approved operational procedures as required by
their aircraft and type of operation.
The ST3400H is not the pilot nor is it a substitute for the pilot’s judgment;
it is a display and computer. However, because it is designed to only alert
when the aircraft is outside normal flight envelopes in relation to terrain,
we recommend that all alerts should result in immediate and appropriate
action by the pilot. A Warning should
always
result in an evasive
maneuver.
4.4 TAWS
Inhibit
A pilot selectable TAWS INH function allows the Pilot to disable all alerts.
When selected, all FLTA and GPWS alerts are inhibited, and the terrain is
removed from the screen. All altitude Callouts will still be enabled.
4.5 Display
4.5.1 Topographic
Display
A Pilot Selectable TOPO (Topographic) view shows all terrain, in
sectional-chart colors. Terrain and Obstacles are shown RED when
above the aircraft altitude.
4.5.2
Relative Altitude Display
A Pilot Selectable REL view shows only proximate terrain and
obstacles.
4.5.3 Obstacle
Display
The ST3400H displays obstacles above 50’ AGL using the standard
obstacle symbol. Obstacles above 500’ are displayed using the tall
tower symbol (see section on obstacle display).
