BASIC FUEL PLANNING PROFILE

Figure 4-1 shows the basic fuel planning profile for T-6A visual navigation flights. The profile

has three basic segments:

Takeoff to entry point of the first low-level route,

the low-level route, and

the IFR return leg.

Actual fuel figures for climbing to various altitudes and cruising at various altitudes and

airspeeds are found in NATOPS, Appendix A. The total fuel required to arrive at the initial

approach fix (IAF) is computed by totaling the segments.

Takeoff to Descent:

1. The distance differs from takeoff to Point A for the various routes. The initial routing to

each low-level route is defined by the stereo routing. Additionally, the distance covered in the

departure depends on the runway used. This equates to the following "constants":

37 NM from takeoff to TRADR

28 NM from takeoff to CEW263043

2. Mission fuel planning for the departure and initial enroute phase is similar to basic air

navigation flight planning.
