Other Airspace Areas

identified in a published WRA Notice to Airmen

(NOTAM).

b. WRAs. Airspace with defined dimensions and

published by a NOTAM, which is established to

support weather reconnaissance/research flights.

ATC services are not provided within WRAs. Only

participating weather reconnaissance/research

aircraft from the 53

rd

 WRS and NOAA AOC are

permitted to operate within a WRA. A WRA may

only be established in airspace within U. S. Flight

Information Regions (FIR) outside of U. S. territorial

airspace.

c. A published WRA NOTAM describes the

airspace dimensions of the WRA and the expected

activities within the WRA. WRAs may border

adjacent foreign FIRs, but are wholly contained

within U.S. FIRs. As ATC services are not provided

within a WRA, non−participating aircraft should

avoid WRAs, and IFR aircraft should expect to be

rerouted to avoid WRAs.
