Single Frequency Approach (SFA

T-45C TS INav-06

Departure and Terminal Procedures

Prior to issuance of a descent clearance below the

highest initial approach fix altitude established for

any high altitude instrument procedure for the

destination airport (i.e., that point that the “approach”

is considered to commence), the controller will

inform the pilot:

The type of final approach to expect

RADAR vectors will be provided to the final

course

Current weather whenever the ceiling is below

either 1,000 ft (1,500 ft for Air Force controllers)

(SFA - UHF)

aircraft is in instrument weather conditions

The abbreviation “SFA” will be shown after the

heading “COMMUNICATIONS” in the FLIP IFR En

route Supplement when procedures have been

implemented at that station. For those military fields

that do not indicate “SFA” check the RADAR section

of the FLIP (Terminal) for that airfield. If they have

numerous UHF frequencies available you can

request SFA in the remarks section of the DD-175

Pilots receiving this service will not be required to

change frequency from beginning of penetration to

touchdown, except that pilots conducting an en route

descent are required to change frequency when

control is transferred from the Air Route Traffic

Center to the Terminal Facility

Controllers may discontinue the service to all pilots

who cancel IFR Flight Plans during daylight hours

and to those pilots in level flight who cancel IFR

Flight Plans at night
