Flight Planning (En Route)
COMPLETING DD-175 FOR ROUTE OF FLIGHT 2.1.7, 22.214.171.124
As mentioned in the previous workbook lesson, a completed DD Form 175 is one of three documents
required before any IFR flight. The other two are the Single-Engine Jet Flight Log and the Flight Weather
Briefing (DD Form 175-1).
The flight plan serves two purposes. It informs ATC of your desires so an IFR clearance may be issued
and provides search and rescue facilities necessary information in case of an emergency. Emergency
information can include such facts as your route, fuel on board, and identification of personnel.
The Military Flight Plan, DD Form 175, is used for military flights within the contiguous United States,
within the Honolulu, Alaskan, and San Juan Domestic Control Areas, and between the contiguous United
States and Canada.
The information you need to include in your flight plan varies for each type of flight. Requirements for
filling out a DD Form 175 are found in DOD FLIP General Planning (GP), Chapter 4. In the pages that
follow, the item number corresponds to the item numbers used in the GP.
