MENU The ‘AIRSPACE’ tab provides the following settings:
• CLASS B, CTA—enable/disable alarm for Class B or CTA (ICAO control areas) airspace.
• CLASS C, TMA—provides alarm for Class C or TMA (ICAO terminal control areas) airspace.
• TOWERS, CONTROL ZONES—provides alarm within a 4.3 nm radius from airports with con-
trol towers which are not associated with Class B or Class C airspace. (Typically Class D airspace.)
• RESTRICTED AREAS—enable/disable alarm for restricted areas.
• MOAs—enable/disable alarm for military operations areas.

where a Mode C altitude-encoding transponder is required.
• OTHER SUAs— provides alarm for other special-use airspace categories including: training,
caution, danger, warning and alert areas.

safety. For example, if the buffer is set to 500 feet, and you are more than 500 feet above or
below an airspace, you will not be notified with an alert message. If you are less than 500 feet
from the floor/ceiling limits of the airspace, you will be notified with an alert message.
