What are CFAs?

CFAs refers to Controlled Firing Area, CFA are one of the six special use airspaces. They are airspaces designated contain activities that if not conducted in a controlled environment can be hazardous to a non-participating aircraft.

CFA are not charted, there is no controlling agency to contact, this is unlike some of the special use airspaces such as restricted areas or Warning areas, there are no dimensions in CFA.

Controlled Firing Areas are mostly used for ordinance disposal and testing of large rockets.
However, all activities around a CFA stop when the user spots an aircraft.
