Airspace Settings (cont.)The airspace alarms are designed to provide message alerts in several stages, depending onwhether you are projected to enter the airspace or are just in close proximity. The alerts are:• Airspace Ahead, Less Than 10 minutes — occurs if your projected course willtake you inside an airspace within the next ten minutes.• Airspace Near and Ahead — is displayed when you are within two nautical milesof an airspace and your current course will take you inside the airspace.• Inside Airspace — occurs when you have entered the boundaries of the airspace.• Near Airspace, Less Than 2 nm — appears when you are within two nauticalmiles of an airspace, but your current course will not take you inside the airspace.NOTE: Some airspace altitude limits may be charted in terms of altitude above ground level(AGL). If the actual lower limit of an airspace is charted in AGL, the GPS III Pilot will alert youat any altitude below the upper limit. However, if the actual upper limit is also charted in AGL,the GPS III Pilot will provide the alert at all altitudes.Nearest SettingsRunway Surface determines which surface type or types will be included when display-ing nearest airports on the Nearest Page. Available types include: ‘Any’ (includes waterlanding facilities), ‘Hard Only’ surface, ‘Hard or Soft’ surface and ‘Water Only’ facilities.Min Runway Length determines the minimum allowable runway length when displayingnearest airports on the Nearest Page.To select the nearest airport criteria:1. Highlight the ‘Runway Surface’ or ‘Min Runway Length’ field and press ENTER.2. For ‘Runway Surface’, select the desired surface type and press ENTER.3. For ‘Min Runway Length’, enter the minimum allowable runway length and press ENTER.Due to vertical airspace lim-its, if you fly above or belowan airspace then descend orclimb into the airspace, the‘Inside Airspace’ message maybe the only alert provided.‘Hard Only’ includes onlyconcrete, asphalt, or similarsealed surface runways.85REFERENCESetup: Nearest#?
