5.4 AIRSPACES

The G1000 can display the following types of airspaces: Class B/TMA, Class C:TCA, Class D, Restricted, MOA (Military), Other Airspace, Air Defense Interdiction Zone (ADIZ), and Temporary Flight Restriction (TFR).

The Nearest Airspaces Page, Airspace Alerts Window, and Airspace Alerts on the PFD provide additional information about airspaces and the location of the aircraft in relationship to them.

FLIGHT MANAGEMENT

The Airspace Alerts Box allows the pilot to turn the controlled/special-use airspace message alerts on or off. This does not affect the alerts listed on the Nearest Airspaces Page or the airspace boundaries depicted on the Navigation Map Page. It simply turns on/off the warning provided when the aircraft is approaching or near an airspace.

An altitude buffer is also provided which “expands” the vertical range above or below an airspace. For example, if the buffer is set at 500 feet, and the aircraft is more than 500 feet above/below an airspace, an alert message is not generated, but if the aircraft is less than 500 feet above/below an airspace and projected to enter it, the pilot is notified with an alert message. The default setting for the altitude buffer is 200 feet.

Changing the altitude buffer distance setting:

1)Use the FMS Knob to select the AUX - System Setup Page.

2)Press the FMS Knob momentarily to activate the flashing cursor.

3)Turn the large FMS Knob to highlight the altitude buffer field in the Airspace Alerts Box.

4)Use the FMS Knob to enter an altitude buffer value and press the ENT Key.

Turning an airspace alert on or off:

1)Use the FMS Knob to select the AUX - System Setup Page.

2)Press the FMS Knob momentarily to activate the flashing cursor.

3)Turn the large FMS Knob to highlight the desired field in the Airspace Alerts Box.

4)Turn the small FMS Knob clockwise to turn the airspace alert ON or counterclockwise to turn the alert OFF.

The Nearest Airspaces Page can be used to quickly find airspaces close to the flight path. In addition, a selected frequency associated with the airspace can be loaded from the Nearest Airspaces Page. In addition to displaying a map of airspace boundaries and surrounding area, the Nearest Airspaces Page displays airspace information in four boxes labeled ‘AIRSPACE ALERTS’, ‘AIRSPACE, AGENCY’, VERTICAL LIMITS’, and ‘FREQUENCIES’.

Airspace alerts and associated frequencies are shown in scrollable lists on the Nearest Airspaces Page. The ALERTS and FREQ softkeys place the cursor in the respective list. The FREQ Softkey is enabled only if one or more frequencies exist for a selected airspace.

Selecting and viewing an airspace alert with its associated information:

1)Select the Nearest Airspace Page.

2)Press the ALERTS Softkey; or press the FMS Knob; or press the MENU Key, highlight ‘Select Alerts Window’, and press the ENT Key. The cursor is placed in the ‘AIRSPACE ALERTS’ Box.

3)Select the desired airspace.

4)Press the FMS Knob to remove the flashing cursor.
