Figure 3-24: SVS Invalidity
Synthetic Vision Invalidity
When position and orientation data is invalid or if the aircraft is not
within the valid coverage area (+/- 70 Latitude) of the 71DC Terrain
database or a database failure has occurred, the synthetic vision
function is removed from the display and a fail message (amber ‘SVS’)
is shown along with the standard blue over brown attitude background.
See Figure 3-24.
NOTE
Garmin GNS 400W/430W and 500W/530W (WAAS) units
output simulated position data when the Panel Self Test
page is active. This may cause ESI-500 SVS position to
display at the simulated position, and possibly cause an
Alert. Do not use the ESI-500 SVS function while the GPS is
in the Panel Self Test Page.
