The Special Use Airspace settings page will allow you turn the controlled/
restricted 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
rstcd : Restricted areas
SUA warnings for prohibited airspace can not be turned off. The ‘alt’ field, located
at the bottom of the SUA settings page, is an altitude buffer which ‘expands’ the verti-
cal 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 setting for the altitude buffer is 200 feet.
