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 Settings’ Window). Auto zoom is suspended while the map pointer is active.
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 navigation map
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’ Window 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 (1000 nm).
»
When the minimum ‘look forward’ time is set to zero, the lower limit becomes 1.5 nm.
