FAA Flight Plan: Types, Filing Requirements, and How to Close

An FAA flight plan is a record you file with Flight Service or air traffic control that describes your aircraft, route, timing, and souls on board, so ATC can work you into the system and search-and-rescue can find you if you never arrive. Operating under Instrument Flight Rules in controlled airspace always requires a filed flight plan and an ATC clearance; a VFR flight plan is voluntary in most situations but becomes your lifeline if you go overdue.¹ Failing to file when required can bring a civil penalty of up to $1,875 per violation.²

VFR, IFR, and Composite Plans

Two main categories exist, and they do different jobs. A VFR flight plan is filed when weather allows navigation by outside references, and it functions almost entirely as a safety net. Flight Service Stations hold the plan and start looking for you if you don’t arrive within 30 minutes of your estimated arrival time.³ ATC does not monitor VFR flight plans and cannot see them on their screens. Filing one gives you no traffic services, no separation, and no routing. Its sole job is search and rescue.

An IFR flight plan puts you directly into the ATC system. You receive a clearance with a specific route and altitude, and controllers provide positive separation from other IFR traffic for the whole flight. You need an instrument rating, the aircraft needs appropriate equipment, and weather below VFR minimums makes IFR the only legal option. All operations in Class A airspace, from 18,000 feet MSL up to Flight Level 600, must be conducted under IFR regardless of weather.⁴

A composite flight plan covers a trip flown IFR for one portion and VFR for another. FSS transmits separate flight plan messages to the appropriate ATC facilities for each IFR segment.⁵ Each leg is filed with its own type designation. If you’re departing IFR and transitioning to VFR later, you cancel IFR with ATC at the transition point and then activate the VFR portion with FSS.

When Filing Is Required

Most of the time, filing a VFR flight plan is your choice. Mandatory triggers fall into a few specific categories.

IFR in Controlled Airspace

Any time you fly under instrument flight rules in controlled airspace, you need both a filed IFR flight plan and an ATC clearance before departure.¹ Class A airspace makes IFR mandatory for every aircraft regardless of conditions, so any flight at or above 18,000 feet MSL requires a plan.⁴

Air Defense Identification Zone Operations

Flying into, within, or from a departure point inside an ADIZ requires you to file, activate, and close a flight plan with the appropriate facility. If you’re operating VFR, that plan must be designated as a Defense VFR (DVFR) flight plan.⁶

Flights Between the U.S., Mexico, and Canada

No one may operate a civil aircraft between the United States and Mexico or Canada without filing either an IFR or VFR flight plan.⁷ This applies in both directions, with no exception for short hops across the border in good weather.

Recommended but Not Required

Even when not legally required, a VFR flight plan is cheap insurance for flights over remote terrain, large bodies of water, sparsely populated areas, or at night. Without one, nobody will know to start looking for you if you go down in an area with no radar coverage. Filing takes a few minutes. The search-and-rescue delay without one can be measured in days.

Information You Need to Provide

The standard domestic form is FAA Form 7233-1. The international format (FAA Form 7233-4) is mandatory for flights leaving U.S. domestic airspace and for flights requesting performance-based navigation routing.⁸

For a VFR flight plan, the regulations require:⁹

Aircraft identification (N-number, and radio call sign if applicable)
Aircraft type (make and model designation)
Pilot in command’s full name and address
Departure point and time
Route, altitude, and true airspeed
Destination and estimated time en route
Fuel on board, in hours
Number of persons on board
Any other information the pilot or ATC considers necessary

The actual FAA form also asks for the aircraft’s color and the pilot’s telephone number, both of which help search-and-rescue teams if they need to find you.¹⁰ For IFR operations, you also add an equipment suffix code that tells ATC what navigation and transponder capabilities your aircraft has.⁸

The IFR Alternate Airport Rule

IFR flight plans must include a designated alternate airport unless the weather forecast meets specific conditions. You can skip the alternate if the destination has a published instrument approach and the forecast shows ceilings at least 2,000 feet above the airport and visibility of at least 3 statute miles for the period from one hour before to one hour after your estimated arrival.¹¹ Pilots remember this as the “1-2-3 rule”: 1 hour, 2,000 feet, 3 miles. If the forecast doesn’t meet all three, you need an alternate.

How to File

You have several ways to get the plan into the system.

Flight Service

The traditional method is calling Flight Service at 1-800-WX-BRIEF. A briefer takes your information verbally, gives you a weather briefing, and enters everything into the system. You can also contact FSS over the radio if you’re already airborne and need to file or amend a plan. It’s slower than digital filing, but it puts you in direct contact with someone who can flag weather issues.

Online and Electronic Filing

Most pilots today file electronically through the Leidos Flight Service web portal (1800wxbrief.com) or through Electronic Flight Bag apps on a tablet. These platforms let you enter the data yourself, pull weather and NOTAMs automatically, and submit directly to the FAA system, which routes the plan to the appropriate ATC facility. Electronic filing is faster and reduces transcription errors.

Timing for IFR

The FAA recommends filing IFR flight plans at least 30 minutes before your proposed departure time so ATC has enough time to process the plan and issue your clearance.¹² If you’re planning to fly above Flight Level 230, the FAA requests you file at least four hours in advance to help with traffic flow planning. ATC accepts IFR plans up to 22 hours before departure. Once you’re within roughly 45 to 60 minutes of your proposed departure time, the plan enters a lock-out window where changes require phone or radio coordination rather than electronic amendment.

Activating, Amending, and Closing

Filing is only step one. A flight plan sitting in the system does nothing until it’s activated, and it becomes a problem if you don’t close it.

Activation

VFR flight plans require you to actively open them. Contact FSS by radio or phone just before or shortly after takeoff and report your departure. If FSS doesn’t receive a departure report within at least one hour of your proposed departure time and you haven’t made other arrangements, the plan is automatically canceled.¹³ Most ATC centers also delete unactivated IFR flight plans about one hour after the proposed departure time.¹⁴

IFR flight plans work differently. When ATC issues your clearance and you depart, the plan activates through the ATC system without a separate call to FSS.

Amendments

Things change in flight. Your destination might shift, weather might force a route change, or your time en route might differ from what you filed. For IFR flights, tell the controlling ATC facility and they’ll update your clearance. For VFR plans, contact FSS to amend the plan so your expected arrival information stays accurate. Under IFR, you must follow the route in your clearance and cannot deviate without ATC approval.¹⁵

Closing

When you land, you are responsible for closing your flight plan. For IFR flights arriving at a tower-controlled airport, the tower normally closes the plan automatically. At a non-towered airport, you need to contact FSS yourself. VFR flight plans never close automatically. You must call FSS after landing every single time.

What Happens If You Don’t Close a VFR Plan

The consequences escalate quickly. FSS considers your aircraft overdue if you haven’t arrived within 30 minutes of your filed estimated time of arrival and they can’t reach you.³ At that point, they start an Information Request, contacting the destination airport, calling your listed phone number, and reaching out to other facilities to determine your location. If those inquiries don’t locate you, the situation escalates through progressively more urgent search-and-rescue phases, eventually involving the Civil Air Patrol and other agencies. Pilots who repeatedly trigger unnecessary searches attract FAA enforcement attention. Setting a phone reminder or putting “CLOSE FLIGHT PLAN” on your post-landing checklist is the simplest fix.

Penalties for Violations

Operating under IFR in controlled airspace without a filed flight plan and clearance is a regulatory violation. The original statutory penalty was capped at $1,000 per violation, but inflation adjustments have raised the maximum civil penalty for an individual pilot to $1,875 per violation as of late 2024.² Beyond fines, the FAA can take certificate action against your pilot certificate, ranging from a warning letter to suspension, depending on severity and whether there’s a pattern. For ADIZ violations, the stakes are higher: flying into an ADIZ without a filed flight plan can trigger a military intercept and a much more aggressive enforcement response.

Keeping Your Flight Off Tracking Sites

Once you file a flight plan and your aircraft is transmitting ADS-B data, your movements become potentially visible to flight-tracking websites and apps. The FAA’s Limiting Aircraft Data Displayed (LADD) program lets aircraft owners and operators request that their tracking data be restricted.¹⁶

LADD offers two levels of protection. FAA Source blocking limits your flight data to FAA internal use only, so no tracking vendor receives it and no public site can display your movements; the tradeoff is that you also lose the ability to track your own aircraft through those services. Subscriber Level blocking still sends your data to tracking vendors but bars them from publicly displaying it, and you can contact a vendor directly for selective access to your own flights.

Requests go through an online form at the FAA’s LADD page, by email to ladd@faa.gov, or by mail. You’ll need your registration number, ICAO address, aircraft make and model, and contact information. The FAA processes changes on the first Thursday of each month, so requests submitted by the 15th of a month typically take effect the following month.¹⁶ One limitation: LADD only controls data flowing through FAA systems. Third parties with their own ADS-B receivers can still capture your aircraft’s transmissions directly.
