Smart Airspace
The Smart Airspaces selection filters airspaces to show the ones appropriate for
your altitude. Garmin' s Smart Airspace™ feature aids visual clarity on-screen by
de-emphasizing airspace that' s well above or below the aircraft' s current altitude.
The vertical separation is 1,000 feet at sea level and the vertical separation will
gradually increase to 2,000 feet until the aircraft reaches 10,000 feet. Anything
above 10,000 feet keeps the 2,000 feet vertical separation.
NOTE: Smart Airspace only changes the depiction of the airspace on the
moving map display. It does not alter the Airspace Alerts that can be set
on the System-Alerts portion of the system.
