FLIGHT MANAGEMENT
AUTO ZOOM
Auto zoom allows the system 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 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
