For the purpose of this part certain terms are defined as follows:

(a) Alternate use. Use of the aviation facility, specified in the flight plan, to which an aircraft may divert when a landing at the point of first intended landing becomes impractical because of weather. (Aircraft may not be dispatched, prior to takeoff from the airport of origin, to a facility licensed for alternate use.)

(This definition does not include aircraft carriers nor any other type of naval vessel with a landing area for aircraft.)

(e) Government aircraft. Aircraft owned or operated by any department or agency of either the United States or a foreign government (except a foreign government-owned aircraft operated for commercial purposes). Also aircraft owned by any department, agency, or political subdivision of a State, territory, or possession of the United States when such local government has sole responsibility for operating the aircraft. Government aircraft includes:

(g) Official business. Business, in the interest of the U.S. Government, which personnel aboard an aircraft must transact with U.S. Government organizations or personnel at or near the naval aviation facility concerned. Use of a facility to solicit U.S. Government business is not “official business.”

(h) Provisional use. Use of a naval aviation facility for the purpose of providing adequate service to a community where, because of repair, construction or the performance of other work, the regular civil airport servicing the community is not available for an extended period. (An aircraft may be dispatched prior to takeoff from the airport of origin to a naval aviation facility authorized for provisional use.)
