special aerospace defense exercise (SPADE)

The flight of one or more military aircraft on a NOPAR (do not pass to air defense radar) IFR (instrument flight rules) flight plan to conduct a test of the aerospace surveillance, detection, and identification capability. If identification by interception of these aircraft is also planned, it will be contingent upon the approval of a prearranged altitude reservation prior to takeoff.
