RECOMMENDED PROCEDURES FOR GA-EGPWS
ALERTS IN FLIGHT
“Terrain Ahead”
or
“Obstacle Ahead”
Condition: Aircraft flight path is in conflict with terrain/obstacle.
Action: Take IMMEDIATE action to adjust flight path away from
threat until alert/warning ceases.
“Caution Terrain”
or
“Caution Obstacle”
Condition: Aircraft flight path is in conflict with terrain/obstacle.
Action: Adjust flight path as required away from threat until
alert/warning ceases.
“Too Low”
or
“Too Low Terrain”
Condition: Insufficient terrain clearance for phase of flight.
Action: Adjust flight path to recover safe terrain clearance until
alert ceases.
“Check Altitude” Condition: Abnormal difference between GPS, Geometric and/or
pressure altitude information in GA-EGPWS.
Action: Check all available aircraft altitude information. Ensure
correct altimeter setting, altimeters cross-check and are
not stuck.
“Don’t Sink” Condition: Aircraft is loosing altitude during take-off climb.
Action: Re-establish positive rate of climb.
“Sinkrate” Condition: Rate of descent is excessive for current height above
terrain.
Action: Reduce rate of descent.
“500 Above”
or
“500”
Condition: Aircraft is approximately 500 feet above nearest known
runway (within 5 nm).
Action: Assure aircraft is in position for normal landing.
“Too Low Gear”
or
“Too Low Flaps”
Condition: Aircraft configuration of Gear or Flap position is not
consistent with altitude above terrain.
Action: Deploy Gear or Flaps consistent with approach to land-
ing.
“Bank Angle” Condition: Aircraft roll angle is greater than 40 degrees to 50
degrees depending upon altitude.
Action: Ensure proper terrain clearance for excessive bank
(roll) conditions.
