leaving these three blocks empty, until the time of the weather brief. At this pointjust before the

weather briefinga final check of the weather can be made, and two of those three blocks can be

filled in. The alternate airfield block is selected according to the procedures described in Chapter

One and the altitude block will be discussed shortly. Then, a copy of the DD 175 is given to the

weather office for a briefer to prepare a DD 175-1. After receiving the weather briefing, the last

block can be filled in (the weather briefing number), and the flight plan can be turned in to Base

Operations or the local ATC agency for filing and entering in to the ATC computer system.

DD 175-1 FLIGHT WEATHER BRIEFING FORM

The DD 175-1 Flight Weather Briefing Form provides a common format for all military (and

DoD) aircrew to receive a weather briefing from the local meteorology office regardless of

location. However, when using other types of flight plans, such as the daily flight schedule, the

DD 175-1 might not be filled out, but a substitute presenting this information must still be used

to give the aircrew a complete picture of the expected weather. For this reason, OPNAVINST

3710.7 states the following requirements regarding the use of the Flight Weather Briefing form:

A DD 175-1, flight weather briefing, shall be completed for all flights to be conducted in

Instrument Meteorological Conditions (IMC). For VFR flights using the DD 175, the following

certification on the flight plan may be used in lieu of a completed DD 175-1:

BRIEFING VOID ________Z, FLIGHT AS PLANNED CAN BE CONDUCTED

UNDER VISUAL FLIGHT RULES. VERBAL BRIEFING GIVEN AND HAZARDS

EXPLAINED. FOLLOWING SIGMETS ARE KNOWN TO BE CURRENTLY IN

EFFECT ALONG PLANNED ROUTE OF FLIGHT____________________________.

HAZARDS___________________________.

____________________________

(SIGNATURE OF FORECASTER)

The above certification is known as the VFR Certification Stamp. In order to use the VFR

Stamp, the pilot must file VFR for the entire planned route, the pilot must request the stamp, and

the stamp is available only at the forecaster's discretion.

The flight weather briefing may be accomplished by a meteorological forecaster, when available,

or through an autographic, telephonic, weather vision, or certified Internet/intranet system when

no forecasters are available.

Figure 4-2 shows a blank Flight Weather Briefing Form divided into five sections:

Mission/Takeoff Data, En Route Data, Terminal Forecasts, Comments/Remarks, and the Briefing

Record. In fact, the DD 175-1 was designed to provide specific information corresponding to the

three phases of any flighttakeoff, en route, and landing as found in the first, second, and third

sections.
