If a terrain caution or warning occurs, all navigation maps automatically adjust to the smallest map range
clearly showing the potential impact areas. 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 PFD and MFD. Control of the ranges
at which the auto zoom occurs is done by setting the minimum and maximum 'look forward' times (set on the
Map Settings Window for the Map Group). These settings determine the minimum and maximum distance
to display based upon the aircraft' s ground speed.
• Waypoints that are long distances apart cause the map range to increase to a point where many details on
the map are decluttered. If this is not acceptable, lower the maximum look ahead time to a value that limits
the auto zoom to an acceptable range.
• Waypoints that are very short distances apart cause the map range to decrease to a point where situational
awareness may not be what is desired. Increase the minimum look ahead time to a value that limits the auto
zoom to a minimum range that provides acceptable situational awareness.
• Flight plans that have a combination of long and short legs cause the range to increase and decrease as
waypoints sequence. To avoid this, auto zoom can be disabled or the maximum/minimum times can be
adjusted.
• The 'time out' time (configurable on the Map Settings Page for the Map Group) determines how long auto
zoom is overridden by a manual adjustment of the range knob. At the expiration of this time, the auto
zoom range is restored. Setting the 'time out' value to zero causes the manual override to never time out.
• When the maximum 'look forward' time is set to zero, the upper limit becomes the maximum range available
(2000 nm).
• When the minimum 'look forward' time is set to zero, the lower limit becomes 1.5 nm.
Configuring automatic zoom:
1) Press the MENU Key with the Navigation Map Page displayed. The cursor flashes on the 'Map Settings' option.
2) Press the ENT Key. The Map Settings Menu is displayed.
3) Select the 'Map' group.
4) Press the ENT Key.

are from zero to 999 minutes.
9) Use the FMS Knobs to set the time. Press the ENT Key.
10) Repeat step 9 for 'Min Look FWD' (zero to 99 minutes) and 'Time Out' (zero to 99 minutes).
11) Press the FMS Knob to return to the Navigation Map Page.
