single-frequency approach

single-frequency approach

A service provided under a letter of agreement to military single-piloted turbojet aircraft that permits the use of a single UHF (ultrahigh frequency) frequency during the approach for landing. Pilots will not normally be required to change the frequency from the beginning of the approach to touchdown, but those conducting an en route descent are required to change the frequency when control is transferred from the air route traffic control center to the terminal facility.
