Operation - Panel Mount
Altitude of 500 ft
This condition (Figure 2-40), also known as a subset of GPWS Mode
6, occurs when the aircraft descends within 500 ft of the terrain
during enroute mode, or when the aircraft is in enroute mode in level
ight but the terrain below rises up within 500 ft of the aircraft. It also
occurs when the aircraft descends within 500 ft of the nearest runway
threshold elevation during terminal or approach mode. When any of
these conditions occurs, TAWS issues an aural 500 ft altitude callout
(“ve hundred”). The 500 ft altitude callout does not occur when the
aircraft is ascending or during departure or missed approach mode.
The callout is ready to play again only after the aircraft ascends to 700
ft above the terrain or runway.
