DD 175 MILITARY FLIGHT PLAN
A partially completed DD 175 is pictured below in Figure 4-1. The form is used to provide ATC
agencies with the planned route of flight, for easier handling and direction of aircraft. It contains
basic information on the top-right, such as the date, aircraft call sign, and type of aircraft. The
center section presents the route, including departure point, time, destination, and estimated time
en route (ETE), as well as requested altitude and route(s) of flight. At the bottom, above the list
of crewmembers/passengers, the DD 175 provides space for other important details, such as the
selected alternate landing field and an indication of a review of the weather.
