The Special Use Airspace settings page will allow you turn the controlled/restrict-
ed airspace message alerts on or off. This will not affect the alerts being listed on the
nearest page. It will simply turn off the warning when you are approaching or near an
SUA. Warnings can be turned off for the following airspaces:
class B/cta : ICAO control area moa: Military operations area
class C/tma : ICAO Terminal Control Area other: Other areas
rstc: Restricted areas
SUA warnings for prohibited airspace cannot be turned off. The ‘alt’ field, located at
the bottom of the SUA settings page, is an altitude buffer which ‘expands’ the vertical
range of the SUA, so you will be notified if you are within a certain range of an SUA. For
example, if the buffer is set at 500 feet, and you are 500 feet above or below an SUA, you
will not be notified with an alert message; if you are less than 500 feet above or below an
SUA and projected to enter it, you will be notified with an alert message. The default set-
ting for the altitude buffer is 200 feet.
