GA-EGPWS COCKPIT LAMPS & SWITCHES

A representative sample of a possible annunciator and switch installation
is pictured below. Other configurations are at the discretion of the
installer and operational requirements of the aircraft.

Typical Annunciator

GA-EGPWS SYSTEM LIMITATIONS

* The GA-EGPWS is a Situational Awareness tool, and an alerting and

warning device. It is not to be used for navigation of the aircraft.

* The GA-EGPWS must have an operating source of GPS information,

with enough satellites in view to provide GPS data within the accuracy
requirements of the system.

* Without the optional Outside Air Temperature (OAT) input for correc-

tions, “Geometric Altitude” may have errors during rapid climbs or
descents in non-ISA conditions. This may affect alerting/warning times
and proper altitude reference on the Terrain Display.

* The Terrain, Obstacle and Runway database information is not all-

inclusive.

* The GA-EGPWS “Look-Ahead” alerting and warning, and Runway

Field Clearance Floor (RFCF) functions are gradually “de-sensitized”
as an aircraft nears a known runway. Aircraft operating in close proxim-
ity to known runways may experience very short or no advance warn-
ings with respect to terrain or obstacles in this area. (See sections on
GA-EPWS “Look-Ahead” and RFCF).
