DD-175 Construction

6.8. DD-175 CONSTRUCTION:

6.8.1. Each student will prepare a practice DD-175 for each low-level sortie. The example in

figure 6-15 is for a NPA 500 stereo flight plane. While DD-175s prepared for stereo routes are

not filed at base operations, students can expect their instructors to do a thorough check for

accuracy on each DD-175. Some differences between the T-34 and T-1A/T-39 DD-175s are:

NOTE: the numbers listed below correspond to the blocks in Figure 6-19

1. Date - date of flight.

2. Radio call - BUCK or DREAD (VT-4)/ KATT or BREVET (VT-10).

3. Aircraft designation/TD code - T/BE40/G for T-1A, or SBR1/A for T-39.

4. Type of flight plan - check what is appropriate for each line.

5. Estimated true airspeed - plan according to stereo route.

6. Point of departure.

7. Proposed departure time (Z) - for takeoff time and subsequent IFR segments enter the

proposed time for beginning that segment. Adjust take-off time such that low-level entry occurs

at the flight-scheduled times.

8. Initial cruising altitude - plan according to stereo routes.

9. Route of Flight

a. For composite flight plans do not combine IFR and VFR route segments on the same

line.

b. If a SID is to be used start route of flight with SID's name and transition point.

10. For interim VFR leg enter the last point of the preceding low level under point of departure.

Enter proposed time off preceding low level route under proposed departure time.

11. Each low level route will be given its own line with no airspeed, point of departure or

proposed departure time or altitude listed!

12. Remarks: Each training route shall be listed with identifier, entry time, and exit time in Zulu.

EXAMPLE: If entering VR1006 at 1600Z and exiting at 1631, the proper annotation is:

VR1006E1600X1631.

13. Rank/Honor - as necessary.
