Air-to-Ground, the zoom scale is automatically set to a
user selected "Ground" zoom scale. The transition point

Speed and is based on GPS ground speed.

viewing while on the ground and optimal long range
viewing while in flight, without the user having to make
manual zoom scale adjustments while in the takeoff and
landing phases of flight. The Zoom scale is shown in the

The En Route and Ground zoom scales and the transition
point are adjusted under the SYS Function.
