METEOROLOGY FLIGHT PLANNING

CHAPTER FOUR

Figure 4-1 DD Form 175, Military Flight Plan

For this chapter, you will use the following scenario, which began as an assignment to fly from

NAS Memphis, Tennessee (NQA), to Tinker AFB, Oklahoma (TIK). Before choosing the route

of flight, our aviators first check for any weather warnings/watches. Remember, the first step for

any flight planning should always be to check for any WW, MWA, or In-Flight Weather

Advisory that may affect the flight, because severe weather or a valid WW may result in a change

of plans or the cancellation of the flight (as stated in Chapter Three).

Our aviators found no weather warnings affecting these bases or the area in between them.

However, at this point, they determined the weather was not unmistakably VFR, so two possible

alternate airfields were chosen, along with the following data, which has already been entered on

the DD 175 above:

Planned routeKNQA to KTIK

Departure time/date1230Z, 25 July 20XX

ETE2 hours, 12 minutes

Possible alternatesKSPS and KTUL

ETE to either alternate38 minutes

Aircraft category/type"B," T-6 T/A

It is at this point we join the scenario to see how weather fits into the preflight planning process.

As stated above, this DD 175 is partially filled out. Notice there are three blocks containing

asterisks (**). Normally, when flight planning, the DD 175 can be completed to the point of
