When must I file an ICAO flight plan?

If your flight meets any of these criteria, you must file an ICAO flight plan:

1. Your flight will enter international airspace, including Oceanic airspace controlled by FAA facilities.

2. Your flight expects routing or separation based on Performance Based Navigation (PBN), ie: RNAV SIDs and STARs.

3. Your flight will enter Reduced Vertical Separation Minima (RVSM) airspace, ie: FL290 or above.

4. Your flight expects services based on ADS-B.
