When a terrain threat is detected, a “CAUTION TERRAIN, CAUTION TERRAIN” aural is
generated and GND PROX is annunciated on the PFD. When an obstacle threat is detected, a
“CAUTION OBSTACLE, CAUTION OBSTACLE” aural is generated and GND PROX is
annunciated on the PFD. When alerts are activated, areas which meet the terrain threat alert
criteria are depicted yellow.

Terrain Awareness Alerting (Cont’d)
When a collision with terrain is predicted, an aural “TERRAIN, TERRAIN, PULL UP, PULL UP”
warning is generated and PULL UP is annunciated on the PFD. When a collision with an obstacle
is predicted, an aural “OBSTACLE, OBSTACLE, PULL UP, PULL UP” warning is generated and
PULL UP is annunciated on the PFD. When warnings are activated, areas which meet the terrain
collision alert criteria are depicted red. Terrain will automatically pop up, in MAP mode, on MFD at

Terrain Clearance Floor (TCF)
The TCF function supplements the GPWS function by providing an additional terrain clearance
alert envelope around airports. The TCF criteria is used to determine alert and warning envelopes.
TCF creates an increasing terrain clearance envelope around the intended airport runway directly
related to the distance from the runway. TCF alerts are based on current airplane location, nearest
runway center point position and radio altitude, along with an internal database that includes all
worldwide, hardsurfaced
runways greater than 3500 feet in length.
Penetration of the alert envelope will generate an aural “TOO LOW TERRAIN” and a GND PROX
