Avidyne IFD440 - Other Map Features

IFD400 Series Pilot Guide
Map Subsystem 3-5
NOTE
Map Orientation Without GPS
The map orientation will auto-switch from track-up
orientation to north-up orientation when GPS is lost.
Pilots who leave the map orientation in track-up during
shutdown may notice the map will start up in north-up
until a GPS position fix is available, at which time the
map will auto-switch to track-up.
NOTE
Terrain Resolution
The map uses 9 arc-sec terrain data globally. There are
however, some locations where the terrain database fills
in missing terrain cell data and the map terrain will
visually appear to be a lower resolution background in
those locales.
