{{Use dmy dates|date=April 2023}}
In aviation, a '''single frequency approach''' ('''SFA''') is a service for a military single-piloted [[turbojet]] aircraft to use a single [[UHF]] frequency during their landing approach. Circumstances permitting, pilots will not be required to change their frequency when they switch from [[ARTCC]] to [[Terminal Control Center|terminal facility]] control when conducting an SFA.

In the U.S., per the [[FAA]], [[Air traffic controller|controllers]] are not allowed to require a frequency change from aircraft conducting an SFA unless:
* Pilot has completed landing or low approach
* Aircraft is in [[Visual flight rules|VFR]] conditions during daylight hours
* Pilot requests a frequency change
* Emergency situation exists
* Aircraft is cleared for a visual approach
* Pilot cancels their [[Instrument flight rules|IFR]] flight plan [http://www.faa.gov/ATPUBS/ATC/Chp5/atc0510.html#5-10-15]

If a change of control is necessary, controllers will hand off the frequency to each other, instead of having the pilots change the frequency on their radio.
