DD Form 1801 International Flight Plan
What Is DD Form 1801?
DD Form 1801, DoD International Flight Plan is a document used by military pilots operating an aircraft on flights rom, to, or within international airspace according to International Civil Aviation Organization (ICAO) rules and procedures. The aircraft cannot be flown until a flight plan has been filed.
An updated DD Form 1801 fillable version was released by Department of Defense (DoD) in May 1987 and is available for digital filing and download below or can be found through the Executive Services Directorate website.
The DD Form 175, Military Flight Plan is a form related to the DD 1801 and used for all non-local flights originating from U.S. airfields that have a military operations department.
How to Fill out DD Form 1801?
Procedural guidelines and additional information can be found in the Training Circular (TC) 3-04.5 (Instrument Flight for Army Aviators) released in April 2017.
The DD Form 1801 - as well as the DD Form 175 or their substitutes - is filed prior to the flight. The form requires identifying the aircraft, any special equipment on board, the departure and arrival points, the time of the departure, cruising speed, route and other flight data.
General DD Form 1801 instructions are as follows:
- Use capital letters;
- Adhere to the required format;
- Record time in Coordinated Universal Time (UTC, or Zulu);
- Use the 24-hour format to report time.
If the departure is delayed for an hour or more, the aviator must request the change through the tower or directly to the tie-in flight service station (FSS).
To avoid any possible delays in receiving a departure allowance from air traffic control (ATC), an aviator is required to complete the DoD International Flight Plan at least 30 minutes before the estimated departure time.
The local commanders establish whether the DD 1801 and the DD 175 should be accompanied with the DD Form 175-1, Flight Weather Briefing prior to the flight. Weather information should be obtained from a U.S. military weather facility. If it is not available, the aviator has to consult the DoD or the DoD Flight Information Program (FLIP) for guidance.
The completed DD 1801 should be submitted in person to the nearest automated flight service station (AFSS) or air traffic control tower (ATCT). The form can also be submitted via telephone or computer by means of the Direct User Access Terminal System (DUATS). If these ways are inaccessible, the plan can be submitted using a radio.
