IFR Flight Plans

Here is a super-concise summary of when, what, and how to file for IFR flight plans.

When:

An IFR flight plan must be filed (and clearance obtained) before operating an aircraft in controlled airspace under IFR. § 91.173.

What:

An IFR flight plan must include the same information as a VFR flight plan, plus an alternate airport (unless the first airport of intended landing has a published IAP and the forecast 1hr before and after ETA is at least 2,000’ CIG and 3 SM visibility). § 91.169. You also need to include ICAO equipment codes; here is ForeFlight’s quick guide to them.

How:

(1) The FAA’s official means of filing a flight plan is through Flight Service, which is available by phone at 1-800-WX-BRIEF or online at www.1800wxbrief.com .                                                              

(2) Third party EFB apps also can file flight plans (e.g., ForeFlight or Garmin Pilot).
