Airspace
Airspace alarms are designed to provide message alerts in several stages, depending on whether you are
projected to enter an airspace or are just in close proximity. The GPSMAP 196 provides the following
airspace alerts:
• Ahead—your projected course will take you inside an airspace within the next ten minutes or less.
• Near—you are within two nautical miles of an airspace, but not projected to enter it.
• Near & Ahead—you are within two nautical miles of an airspace and your current course will take
you inside the airspace.
• Inside Airspace—you are within the boundaries of the airspace.
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 GPSMAP 196 will alert
you at any altitude below the upper limit. However, if the actual upper limit is also charted
in AGL, the GPSMAP 196 will provide the alert at all altitudes.
Alarms for most categories by be turned off, except for Prohibited Areas. Disabling an
airspace alert will prevent the alert message, but the airspace boundary will still appear on
the map.
If you fl y above or below an airspace, then descend or climb to enter the airspace, the
‘Inside Airspace’ message may be the only alert provided! The ‘Airspace Ahead’ and/or
‘Airspace Near’ messages will not occur if you are outside the vertical limits defi ned by the
airspace plus the altitude buffer setting.
