Garmin' s Helicopter Terrain Awareness Warning System (HTAWS) is an
Com/Nav
optional feature to increase situational awareness and aid in reducing controlled
FPL flight into terrain. Garmin HTAWS is TSO-C194 authorized. Units installed in
helicopters that do not have HTAWS installed will display HTerrain Proximity.
Direct-To
This is noted by the five color terrain scale which is appropriate to the low
altitude operating environment for helicopters.
Proc
HTAWS provides visual and aural annunciations when terrain and obstacles
are a hazard to the aircraft.
