AIM ¶ 5-1-15 — Canceling IFR Flight Plan
AIM 5-1-15 explains how and when to cancel an IFR flight plan—VFR conditions, towered vs non-towered fields, and pilot responsibilities after cancellation.
Per 14 CFR 91.153 and 91.169, the pilot-in-command must notify FSS or ATC when canceling or completing a flight plan. AIM 5-1-15 explains how this works for IFR flights.
You may cancel an IFR flight plan any time you're in VFR conditions outside Class A airspace by telling the controller or station: "Cancel my IFR flight plan." Immediately afterward, you should:
- Switch to the appropriate air/ground frequency
- Squawk the VFR beacon code (1200)
- Climb/descend to a proper VFR altitude
Once canceled, ATC separation, information, and radar services stop. If you want VFR radar advisories (flight following), you must specifically request them.
Key landing scenarios:
- Towered airport (operating tower): flight plan closes automatically on landing.
- Non-towered airport: you must cancel — by radio with ATC/FSS, by phone after landing, or ideally airborne while still able to reach ATC. Canceling airborne quickly frees the airspace for other IFR traffic.
Watch for special airspace (TRSA, Class C, Class B, or DVFR requirements) where additional procedures may apply. If you later need to re-enter IMC, you must file a new IFR flight plan and obtain a clearance.
