Auto Zoom Time Settings
The minimum and maximum look forward times (configurable per airframe and on the Map Setup
page for the ‘Map’ group) determines the minimum and maximum radial distances to display from the
current aircraft position when in north up orientation or from the map center when in heading up,
desired track up, or track up orientations based upon the aircraft’s ground speed.
• The maximum look forward time is the basis for which the maximum zoom range necessary to display
the active waypoint, if possible, is determined.
• The minimum look forward time is the basis for which the minimum zoom range necessary to display
the active waypoint, if possible, is determined.
• The time out time (configurable on the Map Setup page for the “Map” group) determines the amount of
time that auto zoom is allowed to be overridden by a manual adjustment of the range knob unless the
time out value is zero, in which case the override condition never times out.
Final Flight Plan Waypoints
The map adjusts to display any ranges between and including the maximum look forward time (as
described below for “Other Waypoints”) and a default minimum map range of 1.5 nm or 3 km (depending
on system units) when the active waypoint is valid, the final waypoint in the flight plan, and is an airport
or airport runway waypoint. If a direct-to waypoint outside of the active flight plan is activated the new
active waypoint is considered as the final waypoint in the flight plan.
Missed Approach Point Waypoints
The map adjusts to display any ranges between and including a default maximum map range of
2000 nm or 4000 km (depending on system units) and a default minimum map range of 1.5 nm or 3
km (depending on system units) when the active waypoint is valid and is the missed approach point
waypoint.
Other Waypoints
The zoom range is determined based upon the following minimum and maximum look forward time
combinations when the active waypoint is a valid waypoint other than the final flight plan waypoint or
the missed approach point waypoint:
• When the maximum look forward time is greater than the minimum look forward time settings, the
map adjusts to display any zoom ranges between and including the maximum look forward time and
the minimum look forward time.
• When the maximum look forward time is equivalent to the minimum look forward time setting, the
map adjusts to display the minimum look forward time.
• When the maximum look forward time is set to zero, the map adjusts to display any zoom ranges
between and including a default maximum map range of 2000 nm or 4000 km (depending on system
units) and the minimum look forward time.
• When the minimum look forward time is set to zero, the map adjusts to display any zoom ranges
between and including the maximum look forward time and a default minimum map range of 1.5 nm
or 3 km (depending on system units).
