The Smart Airspace function de-emphasizes airspaces above or below the current aircraft altitude. The function
does not require the aircraft present position or flight path to enter the lateral boundaries of the airspace. If the
current aircraft altitude is within 1100 feet of the vertical boundaries of the airspace, the airspace boundary is
shown normally. If the current aircraft altitude is not within 1100 feet of the vertical boundaries of the airspace,
the airspace boundary is shown subdued.
Turning smart airspace on or off:
1) Use the FMS Knob to select the Navigation Map Page.
2) Press the MENU Key, and press the ENT Key. The cursor is placed in the 'Group' Box.
3) Turn the small FMS Knob to highlight the 'Airspace' in the 'Group' Box and press the ENT Key.
4) Turn the large FMS Knob to highlight the 'Smart Airspace' field in the Aviation Map Setup Window.
5) Turn the small FMS Knob clockwise to turn smart airspace 'On' or counterclockwise to turn smart airspace 'Off'.
6) Press the FMS Knob to remove the flashing cursor.
