GPWS - DESCRIPTION
A330/A340 FLEET DSC-34-70-10 P 1/4
FCOM 19 AUG 10
DESCRIPTION
Applicable to:
The Enhanced Ground Proximity Warning System (EGPWS) generates aural and visual warnings
when one of the following conditions occurs at radio altitudes between 30 and 2 450 ft for Modes 2,
4, 5 and between 10 and 2 450 ft for Modes 1 and 3.
Mode ‐ 1 : Excessive rate of descent
‐ Mode 2 : Excessive terrain closure rate
‐ Mode 3 : Altitude loss after takeoff, or go-around
‐ Mode 4 : Unsafe terrain clearance when not in landing configuration
‐ Mode 5 : Excessive deviation below glideslope.
In addition to the basic GPWS functions, the GPWS has an enhanced function (EGPWS) which
provides, based on a worldwide terrain database :
‐ A Terrain Awareness Display (TAD), which predicts the terrain conflict, and displays the terrain on
the ND.
‐ A Terrain Clearance Floor (TCF), which improves the low terrain warning during landing.
The cockpit loudspeakers broadcast, even if turned off, the aural warning or caution messages
associated with each mode. The audio volume of these messages is not controlled by the
loudspeaker volume knobs. (These knobs only allow volume adjustment for radio communication).
PULL UP lights come on to give a visual indication when a PULL UP warning alert is triggered for
Modes 1, 2, and TAD.
GPWS lights come on for caution alerts of Modes 1 to 5, TAD and TCF, on the Captain and First
Officer instrument panels.
Note: A number of airports throughout the world have approaches or departures that are not
entirely compatible with standard GPWS operation. These airports are identified in the
envelope modulation database in such a way that when the GPWS recognizes such an
airport, it modifies the profile to avoid nuisance warnings.
