The DoD may also request the FAA to issue a Certificate of Waiver / Authorization to
allow operation of military UASs on pre‐coordinated flight routes outside of SUA allowing
military UAS to transit to and from the SUA. The military may also fly UASs upon request
from federal / state civilian authorities in accordance with specific DoD policy guidance.
Restricted area airspace designates areas where ongoing or intermittent activities occur
that create usual and often invisible hazards to aircraft. Restricted area airspace is
specifically designated in areas where flight or ground activities must be confined as they
could be considered hazardous to non‐participating aircraft, such as commercial or
general aviation aircraft. RA airspace is bounded by a floor (minimum altitude a plane
can fly) and a ceiling (maximum altitude a plane can fly). Restricted area airspace is
designated under 14 Code of Federal Regulations (CFR) Part 73 and is utilized for
activities such as weapons firing, hazardous flight activity and aircraft testing including
high speed maneuvering, abrupt altitude changes, and other dynamic, nonstandard
aircraft activity such as UAS operations.
The FMR has RA airspace over the installation which is separated into three different
sections. These three sections are identified as R‐2310A, R‐2310B, and R‐2310C.
R‐2310B and R‐2310C are smaller and contained within R‐2310A but at higher altitudes.
While the RA airspace is primarily used for excluding aircraft operations during live‐fire
weapons training activities to protect them from ground‐based weapons firing, it is also
used for UAS training operations. The types of UASs that are used at FMR require the use
of RA airspace to operate, so that they do not risk interfering with other aircraft and vice
versa. Table 5‐4 provides information on the operating parameters associated with each
of the three RA airspace sections.
