The phone rings 40 minutes after you’ve landed. You’re already on the drive home, or grabbing a meal in the FBO, or telling the lineman about your trip. The caller ID says something like “Mountain AFB” or “FSS Center.” Your stomach drops. You forgot to close your flight plan.

As of 2026, when a pilot fails to close a VFR flight plan within 30 minutes of the estimated time of arrival, Flight Service initiates a multi-stage search procedure that escalates from phone calls to ramp checks to an Alert Notice (ALNOT) to an active Civil Air Patrol search mission. The full sequence is governed by FAA Order JO 7110.10 and FAA Order JO 7110.65 and can involve dozens of personnel across multiple agencies — all looking for an aircraft that, most of the time, simply landed safely and forgot to make a phone call.

Here’s what actually happens, step by step, and how to avoid being the pilot at the end of that phone call.

What Triggers the Search?

The clock starts at your ETA. If your flight plan isn’t closed within 30 minutes of that time, the FSS computer system flags your flight as overdue and generates an alert at designated workstations. This is documented in FAA Order JO 7110.10 (Flight Services) and JO 7110.65 (Air Traffic Control), which govern the procedures.

For the FAA’s Eastern Region, the alert actually triggers at ETA plus 25 minutes — a slightly more conservative window. Everywhere else in the U.S., the threshold is 30 minutes.

Flight plans are never closed automatically. There is no system that watches your aircraft land and quietly removes you from the inbound list. The responsibility to close belongs entirely to the pilot — by calling 1-800-WX-BRIEF, using an EFB, clicking the Leidos EasyClose email link, or calling FSS on the radio before landing.

Stage 1: The Phone Call (ETA + 30 minutes)

When the inbound list alert triggers, an FSS specialist begins the communications search. The first call goes to the number you listed on your flight plan — typically your cell phone.

If you answer and confirm you’ve landed safely, the flight plan is closed and the process ends. This is the most common outcome. According to FSS specialists who have shared their experience, a significant percentage of overdue alerts are resolved within the first phone call.

If you don’t answer, the FSS specialist moves to the next step.

Stage 2: Destination Airport Contact (ETA + 30 to 60 minutes)

The specialist calls your destination airport. The exact contact depends on the airport type:

Towered airport. Controllers have records of every aircraft that arrives. The tower checks its logs and confirms whether your aircraft landed. If it did, the flight plan is closed.

Non-towered airport. The FSS calls the FBO and asks someone to perform a ramp check — physically walking the parking ramp and tiedown areas to look for your aircraft. If you’re at a smaller airport, this might mean the line technician walking the entire field looking for your specific tail number.

This is the stage where pilots most often get caught off-guard. As one pilot recounted in a Pilots of America forum thread, “Arrived at SAV in drizzling rain, but good VFR, to be greeted by a line boy in slicker, and thrilled to see us. Go straight to the office, call FSS, they have started a search for you! He had just finished checking every plane in the tiedown area for our number.”

If the FBO confirms your aircraft is on the ramp, FSS closes the flight plan. If not, the search expands.

Stage 3: Adjacent Airports and Records (ETA + 60 to 90 minutes)

If neither the destination tower nor the FBO can confirm your arrival, FSS expands the search to adjacent airports. The specialist calls airports along your route of flight, asking each one to check whether you landed there instead.

The specialist also queries departure records, DUATS/Leidos servers, and any en-route FSS contacts you may have made. If you updated your flight plan en route or received flight following from ATC, those records help establish your last known position.

If your departure airport is your hometown, FSS may also contact local law enforcement and request a welfare check at your home address. As one Pilots of America commenter recalled: “Got dispatched to that once — the pilot was fine, just forgot to close his flight plan. His wife said he going to be in more trouble with her than the FAA.”

Stage 4: The ALNOT (ETA + 2 hours)

If the expanded communications search comes up empty, FSS issues an Alert Notice (ALNOT) at ETA plus two hours — or sooner if all prior inquiries failed, if your aircraft’s known fuel would be exhausted, or if there’s serious concern about safety.

The ALNOT is a formal alert message transmitted to all Flight Service Stations along your route, generally covering 50 miles on either side of your filed route from your last known position to your destination. The ALNOT includes:

Your full flight plan data
Your last known position
Aircraft description
Pilot information

The ALNOT also triggers broader actions:

En-route aircraft are asked to monitor 121.5 MHz for an ELT signal
The information is broadcast on transcribed weather broadcasts (TWEBs)
The appropriate Rescue Coordination Center (RCC) is notified
All FSS facilities in the alert area check their records

The ALNOT is the procedural prerequisite for search and rescue. Per FAA Order JO 7110.10, “An ALNOT must be issued before the RCC can begin search and rescue procedures.”

Stage 5: Active Search and Rescue (ETA + 3 hours or 1 hour after ALNOT)

If the ALNOT search doesn’t locate the aircraft, or one hour after the ALNOT is issued — whichever comes first — an actual search mission begins.

The RCC is contacted with a full status update. The lead agency depends on the location and circumstances:

Civil Air Patrol (CAP). The most common SAR provider for overdue civil aircraft. CAP requires a pilot, observer, and aircraft to be assembled before launching — which can take a couple of hours even after the mission is approved.

Air Force Rescue Coordination Center (AFRCC). Coordinates inland SAR for downed aircraft in the continental United States.

Coast Guard. Handles overwater incidents and coastal regions.

State and local law enforcement. May contribute aircraft, personnel, or ground search resources.

CAP typically launches at daylight unless there is a functioning ELT signal that ground teams can use to locate the aircraft directly. According to AOPA’s research, the average time to locate a downed aircraft with a functioning ELT is about seven hours. Without an ELT, the average jumps to more than 40 hours.

The Reality: Most “Missing” Aircraft Just Forgot to Call

Most overdue flight plan alerts are resolved without ever reaching the ALNOT stage. The pilot answers the phone, confirms safe arrival, and the flight plan is closed. The system works as designed.

But every step of the escalation consumes real time and real resources. FSS specialists make phone calls instead of briefing pilots. Line technicians walk ramps instead of fueling aircraft. CAP volunteers prepare for missions instead of flying training sorties. Law enforcement deputies make house calls instead of patrolling.

Forgetting to close a flight plan isn’t catastrophic. But it’s inconsiderate, embarrassing, and increasingly preventable.

Why VFR Flight Plans Still Matter Despite the Hassle

Some pilots have stopped filing VFR flight plans entirely because of the close-out hassle. That’s a mistake, and the data backs that up.

AOPA cites a study showing that missing pilots who filed a flight plan were located an average of four hours sooner than those without one. Another statistic: 100 percent of pilots considered “missing” who had filed a flight plan were eventually found. The flight plan is what triggers the search — without it, no one knows you’re overdue, no one knows your intended route, and no one can target the search area.

For the cost of a phone call (or an EFB tap) at the end of every cross-country, the flight plan provides a meaningful safety net.

How to Avoid Forgetting

A few practices make forgetting nearly impossible:

Use Leidos EasyClose. When you file online through 1800wxbrief.com, you receive an email with an EasyClose link. Tapping the link closes the flight plan immediately. Many pilots tap it before they’ve even unloaded the aircraft.

Close in the air. Before you cancel flight following or switch to CTAF, request that ATC or FSS close your VFR flight plan. This eliminates the post-landing dependency entirely.

Add closing the flight plan to your shutdown flow. Make it the step right after parking brake on, mixture off, master off. Treat it like securing the aircraft.

Set a phone alarm at ETA. Configure your phone to chime at your filed ETA. If you haven’t closed by then, the alarm reminds you.

Update your ETA en route if you’re going to be late. If your en-route time changes by more than 30 minutes, contact FSS on the radio or by phone and update your flight plan. AOPA’s expert recommendation, mirroring AIM guidance: “If your ETE changes by 30 minutes or more, report a new ETA to the nearest FSS.”

Use flight following AND a VFR flight plan. They serve different purposes. Flight following gives ATC awareness of your aircraft in real time. The flight plan provides SAR coverage if you go silent. Doing both is the gold standard for cross-country flying.

Keep your phone on. The FSS specialist’s first attempt to find you is your cell. Take the call.

The Bottom Line

Forgetting to close a VFR flight plan triggers a real, well-defined, multi-stage search procedure that can ultimately involve FSS specialists, FBOs, adjacent airport operators, law enforcement, Civil Air Patrol pilots, and the Air Force Rescue Coordination Center. Most overdue flight plans resolve within the first phone call. Some escalate. A few become actual search missions for pilots who turned out to be fine — they just forgot to call.

The lesson isn’t to stop filing VFR flight plans. The lesson is to treat closing the flight plan as a non-negotiable item in your post-landing flow — the same way you treat tying down the aircraft, securing the controls, or chocking the wheels. It takes 30 seconds. It saves Flight Service specialists hours of work, prevents potential search-and-rescue mobilization, and avoids that stomach-dropping phone call 40 minutes into your drive home.

Frequently Asked Questions

What happens if I forget to close a VFR flight plan? If a VFR flight plan isn’t closed within 30 minutes of the filed ETA, the FSS computer flags it as overdue and a Flight Service specialist begins the search. The first step is a phone call to the contact number on the flight plan. If that fails, FSS contacts the destination tower or FBO for a ramp check, then adjacent airports, then en-route records. At ETA plus two hours an ALNOT is issued, and at ETA plus three hours an active search mission begins through Civil Air Patrol or other agencies.

When does the FSS start looking for me? The search begins 30 minutes after your estimated time of arrival in most of the U.S. (25 minutes in the FAA’s Eastern Region). The procedure is governed by FAA Order JO 7110.10 (Flight Services) and JO 7110.65 (Air Traffic Control).

How do I close a VFR flight plan? Pilots can close a VFR flight plan four ways: (1) call 1-800-WX-BRIEF, (2) use the Leidos EasyClose email link received after online filing, (3) use the close function in an EFB like ForeFlight or Garmin Pilot, or (4) contact FSS on the radio while still airborne. Flight plans are never closed automatically — the responsibility belongs entirely to the pilot.

What is an ALNOT? An ALNOT (Alert Notice) is a formal message issued by Flight Service at ETA plus two hours when a VFR flight plan remains open and the aircraft cannot be located. The ALNOT is transmitted to FSS facilities along the route, includes the full flight plan and last known position, and triggers en-route aircraft to monitor 121.5 MHz for ELT signals. Per FAA Order JO 7110.10, the ALNOT must be issued before the Rescue Coordination Center can begin SAR procedures.

Should I still file a VFR flight plan even if I’m using flight following? Yes. Flight following provides ATC awareness during the flight but can be cancelled due to controller workload, and ATC isn’t responsible for initiating SAR if you go silent. A VFR flight plan triggers a search 30 minutes after your filed ETA. According to AOPA research, missing pilots who filed flight plans were located an average of four hours sooner than those who hadn’t, and 100 percent of pilots considered missing who had filed flight plans were eventually found.
