AIM ¶ 5-1-7 — Military DoD Flight Plans
AIM 5-1-7 explains which flight plan forms DoD aircraft use in U.S. airspace and when DD Form 1801 (ICAO) is mandatory for military flights.
AIM 5-1-7 covers the flight plan forms authorized for DoD (Department of Defense) aircraft operating in U.S. controlled airspace. While this paragraph is military-focused, civilian pilots may see it referenced when discussing form types and stereo route flight plans.
Key points:
- Inside U.S. controlled airspace, DoD aircraft may use either FAA Form 7233-1 (domestic flight plan) or DD Form 175.
- DD Form 1801 (the ICAO international flight plan) is recommended for IFR flights and is mandatory when:
- The flight will depart U.S. controlled airspace.
- The flight requests routing requiring Performance Based Navigation (PBN).
- The flight requests services requiring capabilities only supported by the international flight plan.
- The order of elements on DD Form 175 mirrors FAA Form 7233-1.
- Civilians filing stereo route flight plans may use FAA Form 7233-1.
Operationally, this ensures that any flight crossing into international or PBN-routed airspace files using ICAO format, so ATC and international authorities receive standardized capability and equipment data.
