Pilot Actions

If an HTAWS warning and associated aural are received, the pilot should
immediately maneuver the rotorcraft in response to the alert unless the terrain
or obstacle is clearly identified visually and determined by the pilot not to be a
factor to the safety of the operation.
A HTAWS caution alert indicates terrain or obstacle nearby. If possible
visually locate the terrain or obstacle for avoidance. A HTAWS warning alert
may follow a HTAWS caution unless the aircraft' s path towards the terrain or
obstacle is changed.
NOTE: Display of terrain and obstacles on the display is supplemental data
only. Maneuvering solely by reference to the terrain and obstacle data is
not recommended or authorized.
