affect pressure altitude sensors. GSL altitude does not require local altimeter settings to determine MSL altitude.
It is a widely-used MSL altitude source.
Terrain and obstacle databases are referenced to GSL. Using the GPS position and altitude, the Terrain-SVS
feature portrays a 3-D picture of the surrounding terrain and obstacles relative to the position and altitude of the
aircraft. GPS position and GSL altitude are used to calculate and predict the aircraft’s flight path in relation to
the surrounding terrain and obstacles. In this way, the pilot can view predicted dangerous terrain and obstacle
conditions.
DISPLAYING TERRAIN-SVS DATA
Terrain-SVS uses yellow (caution) and red (warning) to depict terrain and obstacles (with heights greater than
200 feet above ground level, AGL) alerts relative to aircraft altitude. Colors are adjusted automatically as the
aircraft altitude changes. The colors and symbols in Figure 6-139 and Table 6-16 and Table 6-17 are used to
represent terrain, obstacles, and potential impact points.
