METEOROLOGY FLIGHT PLANNING
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
