Section 2. EMERGENCY PROCEDURES
2.1 Emergency Procedures
No change.
2.2 Abnormal Procedures
a) If the Garmin 500W Series unit GPS navigation information is not available, or is
invalid, utilize other remaining operational navigation equipment installed in the
aircraft as appropriate. If the 500W Series unit loses GPS position and reverts to Dead
Reckoning mode (indicated by the annunciation of "DR" in the lower left of the
display), the moving map will continue to be displayed. Rotorcraft position will be
based upon the last valid GPS position and estimated by Dead Reckoning methods.
Changes in airspeed or winds aloft can affect the estimated position substantially.
Dead Reckoning is only available in Enroute and Oceanic mode; Terminal and
Approach modes do not support DR.
b) If a "Loss of Integrity" (INTEG) message is displayed during:
Enroutefferminal: continue to navigate using GPS equipment and periodically
cross.check the GPS guidance to other approved means of navigation.
c) When a Terrain or Obstacle Awareness CAUTION occurs, verify the aircraft flight
path and correct it, if required.
d) When a Terrain or Obstacle Awareness WARNING occurs, immediately initiate a
maneuver that will provide maximum terrain or obstacle clearance, until all alerts
cease.
