The first box on the DD 175 is the date box and is self-explanatory.

The next section to be filled out is the AIRCRAFT CALL SIGN. Navy/Marine Corps

aircraft may use radio call signs consisting of the Navy service code of "VV" or the Marine

service code of "VM" and the assigned letter/letter or number/letter (tail markings) plus not less

than two or not more than three digits.

3. There are two entries to be made in the next section. The first entry is the aircraft

designation and is self-explanatory. In a formation flight, include the number of aircraft with the

designator of the flight leader's aircraft (One F-4 and one T-38 with the F-4 as the flight leader

would be written as 2/F_4.) DO NOT USE AIRCRAFT MODEL SUFFIXES AS THEY

COULD BE CONFUSED WITH THE TRANSPONDER CODE.

The second entry designates the operable transponder and navigation equipment (TD code)

aboard the aircraft. A list of TD codes is provided in FLIP GENERAL PLANNING (GP).

NOTE

To file IFR, an aircraft must be able to navigate on the "Victor"

airways. The above chart is based on the aircraft being VOR

equipped. If two or more TD codes apply, enter the code

describing the primary navigational equipment to be used during

the flight. In the table above, "T" and "U" denote VOR equipped

aircraft "A" denotes VOR equipped aircraft with DME (TACAN

or DME transceiver radios) capability. Area NAV equipment

consists of an onboard computer which enables an aircraft to

navigate off "Victor" airways on direct routes by electronically

displacing the NAVAID to a VOR radial and DME fix. The T

34C is not area NAV certified.

Enter the type of flight plan to be flown.
