What is VFR flight following and how do I request it?
Learn what VFR flight following means, what ATC provides, how to request it with clear radio phraseology, its limits and how to cancel.
In Aviation & Real-World Flying, the term VFR flight following means a workload-permitting US ATC radar advisory service for pilots operating under visual flight rules. It can provide traffic advisories, safety alerts and controller hand-offs, but it is not an IFR clearance. Request it with your callsign, aircraft type, position, altitude, destination and requested cruising altitude.
What does flight following mean in aviation?
Flight following means ATC has identified your VFR aircraft on its surveillance display and is providing advisory assistance while you remain under visual flight rules.
| ATC may provide | The pilot remains responsible for |
|---|---|
| Traffic advisories for observed aircraft | Seeing and avoiding all traffic, including aircraft ATC cannot see |
| Safety alerts concerning aircraft, terrain or obstacles | Terrain clearance, cloud clearance and legal VFR operation |
| Frequency hand-offs between approach, departure and Center controllers | Monitoring the radio and following accepted ATC instructions |
| Limited vectors, navigation assistance or airport sequencing when available | Weather avoidance, fuel planning and deciding whether a vector can be flown safely under VFR |
The service does not create a general guarantee of separation from other aircraft. Radar, radio and ADS-B coverage may be limited at low altitude, and not every aircraft appears as a usable target. A traffic advisory is never proof that the rest of the sky is clear.
Flight following is also workload permitting. ATC may refuse or terminate it during heavy traffic, equipment limitations or coverage gaps.
What is a VFR report, and is it the same as flight following?
No single US ATC service is normally called a VFR report, and the phrase should not be treated as another name for flight following.
- A VFR position report tells ATC where an aircraft is, usually when requested or when useful. One report does not establish continuing radar service.
- A VFR flight plan records the proposed route and supports overdue-aircraft and search-and-rescue procedures when properly activated. It does not provide ATC traffic advisories.
- A pilot weather report, or PIREP, reports observed weather conditions rather than requesting flight following.
Flight following neither activates nor closes a VFR flight plan. Pilots using both must manage the flight plan separately; our guide to planning a VFR cross-country flight explains where it fits into the wider preparation.
How do I request VFR flight following from ATC?
Ask the appropriate departure, approach or Center controller, preferably before reaching busy or clearance-dependent airspace.
- Prepare the information. Have your full callsign, aircraft type, present position, altitude, destination, route and requested cruising altitude ready. Describe your position from a recognised airport, navigation fix or landmark rather than a local reference the controller may not know.
- Choose the frequency. At a towered airport, Clearance Delivery or Ground may accept the request before departure; local procedures vary. When airborne, use the published departure, approach or Center frequency for the area. Our explanation of how tower, approach and Center responsibilities are divided helps identify the right facility.
- Make a short initial call. On a busy frequency, give the facility, callsign and request only:
Approach, Cessna One Two Three Alpha Bravo, VFR request. Wait for a response rather than transmitting every detail over another call. - Give the complete request. State the aircraft type, position, present altitude, destination, route if relevant and requested altitude.
- Read back the assigned code. ATC will usually issue a discrete transponder code and may tell you to press IDENT. Read back the digits accurately and press IDENT only when instructed.
- Confirm that service has begun. A transponder code alone is not an airspace clearance or proof that flight following is active. Listen for
radar contactor an explicit confirmation that radar service is being provided.
Obtain the airport weather and ATIS before calling on the ground so you are not gathering basic information while the controller waits. If radio work is unfamiliar, our primer on clear initial calls, standard phraseology and readbacks covers the underlying technique.
What does a flight following request sound like?
Use a short opener followed by the details when the controller answers.
Approach, Cessna One Two Three Alpha Bravo, VFR request.
After ATC responds:
Cessna One Two Three Alpha Bravo is a Cessna One Seventy-Two, ten miles southwest of Riverside Airport, three thousand five hundred, VFR direct Lakeview, request flight following, cruising five thousand five hundred.
The controller may ask for the destination identifier, planned route or aircraft equipment. If an assigned heading or altitude would take you into cloud, unsafe terrain or conditions you cannot accept under VFR, say unable, VFR immediately and explain what you need.
What should you say when ATC reports traffic?
Reply traffic in sight only after positively identifying the aircraft visually; otherwise report negative contact or that you are looking.
An aircraft symbol on a cockpit traffic display is not visual contact. Continue scanning after acquiring the traffic, and do not manoeuvre merely because an advisory was issued unless safety requires it or ATC gives an instruction. Ask for an updated position, altitude or suggested vector if the conflict remains unclear.
Does flight following clear you into controlled airspace?
No. Receiving flight following does not by itself authorise entry into every class of controlled or special-use airspace.
- Class B: You must hear an explicit clearance containing words such as
cleared into Class Bravobefore entering. - Class C and Class D: Ensure the required two-way communication has been established with the responsible ATC facility, or that your present controller has specifically coordinated the transition. Follow any instruction to contact the tower or approach controller.
- Restricted areas and temporary flight restrictions: Flight following does not grant permission to enter or excuse compliance with their operating rules.
The mistake we see most often is treating a discrete transponder code as permission to continue through the next boundary. Request the service early, monitor your position and ask the controller before entry if the status of an airspace transition is unclear.
What if ATC says unable flight following?
If ATC cannot provide flight following, continue under normal VFR procedures and remain responsible for every applicable airspace requirement.
If no code has been assigned, remain on the standard VFR code. Wait until workload or coverage improves, or try the next appropriate facility rather than repeatedly calling a saturated frequency.
After a hand-off, if the next controller does not answer, verify the frequency and radio settings, call again, then return to the previous frequency if practical. Do not enter airspace requiring communication on the assumption that an unanswered hand-off completed it.
How do you cancel flight following?
Tell the current controller that you want radar service terminated or need to change frequency; do not simply switch frequencies or select the standard VFR transponder code without advising ATC.
A concise request is Approach, Cessna One Two Three Alpha Bravo, request terminate flight following. If you need to monitor an airport advisory frequency, request frequency change also states the practical reason for ending the service.
Remain on the assigned frequency and code until ATC replies. A normal response includes radar service terminated, squawk VFR and frequency change approved. In the United States, squawking VFR means selecting code 1200. Our guidance on when a VFR pilot may leave an assigned ATC frequency covers hand-offs, termination and lost-contact situations in more detail.
At a towered destination, ATC will normally hand the aircraft to the tower. Near a non-towered airport, the controller may terminate service so the pilot can change to the advisory frequency. Flight following itself requires no separate closing call after ATC terminates it, but any activated VFR flight plan must still be closed separately.
Is VFR flight following available outside the United States?
VFR flight following is chiefly a US term, although other countries provide related traffic, radar or flight-information services under different names.
Eligibility, airspace rules, controller responsibilities and phraseology vary by state. Pilots should use the published procedures for the country concerned rather than transplanting US calls and assuming the resulting service has the same scope.
