Auto Zoom
Necessary Conditions
Auto zoom occurs on all pages on which the following conditions exist:
• Auto zoom is enabled on the system
• No terrain alert condition (caution or warning) exists on the page
• No traffic advisory exists on the page
• A valid waypoint is active by means of an activated direct-to navigation (including OBS mode), or an
activated leg of a loaded flight plan
• The aircraft is in the air
• The map orientation is north up, heading up, track up, or desired track up
Override Conditions
• In the event of a terrain alert condition (caution or warning), the map field of a page allowing auto
zoom and displaying TAWS/TERRAIN data automatically adjusts to the lowest map range in which
the highest priority alert is clearly visible and proceeds to auto zoom when the terrain alert condition
clears.
• In the event of a new traffic advisory alert, the map field of a page allowing auto zoom and capable
of displaying traffic advisory alerts automatically adjusts to the lowest map range in which the traffic
advisory is clearly visible and proceeds to auto zoom when the traffic advisory clears.
• Auto zoom is overridden by a manual adjustment of the range knob while on any page allowing
auto zoom and remain overridden on all pages allowing auto zoom until at least one of the following
conditions occurs:
• A new waypoint becomes active
• The aircraft transitions from on ground to in air
• The time since the last manual adjustment of the range knob exceeds the non-zero
auto zoom time out value.
• A terrain alert condition occurs or new traffic advisory alert occurs.
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.
