Table 10-3 Terrain Database Coverage
NOTE:
Because of higher resolution helicopter terrain data, the world-wide
data won't fit on the terrain database card. Therefore, data is regionalized.
If you have the wrong region database for your present position, then you
get the message that terrain is unavailable for the current location and a
crosshatched pattern on the terrain display.
