MAP RANGE
There are 28 different map ranges available, from 500 feet to 2000 nm. The current range is indicated in
the lower right corner of the map and represents the top-to-bottom distance covered by the map. When the
map range is decreased to a point that exceeds the capability of the G1000 to accurately represent the map,
a magnifying glass icon is shown to the left of the map range. To change the map range turn the Joystick
counter-clockwise to decrease the range, or clockwise to increase the range.

AUTO ZOOM
Auto zoom allows the G1000 to change the map display range to the smallest range clearly showing the
active waypoint. Auto zoom can be overridden by adjusting the range with the Joystick, and remains until
the active waypoint changes, a terrain or traffic alert occurs, the aircraft takes off, or the manual override times
out (timer set on Map Setup Window).
If a terrain caution or warning occurs, any map page displaying TAWS/TERRAIN data automatically adjusts
to the smallest map range clearly showing the highest priority alert. If a new traffic advisory alert occurs, any
map page capable of displaying traffic advisory alerts automatically adjusts to the smallest map range clearly
showing the traffic advisory. When terrain or traffic alerts clear, the map returns to the previous auto zoom
range based on the active waypoint.
The auto zoom function can be turned on or off independently for the PFDs and MFD. Control of the
rangesatwhichtheautozoomoccursisdonebysettingtheminimumandmaximum‘lookforward’times
(set on the Map Setup Window for the Map Group). These settings determines the minimum and maximum
distance to display based upon the aircraft’s ground speed.
