3.6 TAWS PAGE
NOTE: GNS 530 units may* display either a
TERRAIN Page or a TAWS Page, (but not both)
depending upon the ins talled hardware and
configuration.
* Some earlier units are not equipped to support the
TERRAIN and/or TAWS functionality, so therefore will not
have a TERRAIN or TAWS page available.

TAWS Page

To display the TAWS Page, select the NAV Page Group
and turn the small right knob until the TAWS Page is
displayed (Figure 3-34). The TAWS Page displays:
• GPS-derived MSL altitude in increments of 20
feet or 10 meters, depending on unit configura-
tion. The ‘G’ to right of the MSL altitude display
reminds the pilot that altitude is GPS-derived.
• Aircraft ground track
• Terrain Range - Indicates the terrain elevation in
colors relative to the aircraft altitude
• Range marking rings - (1 nm, 2 nm, 5 nm, 10 nm,
25 nm, 50 nm, and 100 nm)
• Heading Indicator - The heading indication on the
TAWS Page always displays ‘TRK’ for Track-up,
unless there is no valid heading
• Obstacles
• Potential Impact Points
NOTE: See Section 13 for a full description of
TAWS functions.

• 360˚ View - View from above aircraft depicting
surrounding terrain on all sides (Figure 3-34)
