Auto Zoom
With a valid flight plan, the Auto Zoom feature will automatically change the
Navigation Map range depending on the distance to the next waypoint in the
flight plan. If enabled, it will also automatically zoom to the SafeTaxi zoom range
when the aircraft is on the ground. Auto Zoom can be overridden at any time by
manually zooming with the RNG keys or enabling OBS mode. Auto Zoom is re-
enabled once one of the following conditions is met:
1) A waypoint is sequenced,
2) the aircraft transitions from "on ground" to "in air,"
3) a point is reached where the Auto Zoom range matches the manual override
range (known as auto-sync),
4) Auto Zoom is toggled of and back on in the Navigation Map Setup page,
OR
5) OBS mode is turned off.
