Single frequency approach
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 facility control when conducting an SFA.
- Pilot has completed landing or low approach
- Aircraft is in VFR conditions during daylight hours
- Pilot requests a frequency change
- Emergency situation exists
- Aircraft is cleared for a visual approach
- Pilot cancels their IFR flight plan
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.
