Please Note
When TAWS is enabled, the color scheme is always displayed. The rules for TAWS are divided into two levels:
1. L1=500 ft. agl / M1=1,000 ft. agl / H1=2,000 ft. agl
2. L2=1,000 ft. agl / M2=2,000 ft. agl / H2=3,000 ft. agl
The TAWS rules allow you to calculate the color scheme to be used for depicting the OCH: Obstacle Clearance
Height.
the oCh
: Obstacle Clearance Height, is the difference of your own altitude (GPS Altitude) less
the Land Elevation:
OCH = ALT – LE
This calculation considers the Lowland and Highland definition, where:
A
- Lowland is the terrain under 3,000 feet of elevation
B
- Highland is the terrain over 3,000 feet of elevation
In the Lowland case, the TAWS colors will be red, yellow and green according to the following
values of the OCH:
