INSTRUMENTS FLIGHT PLANNING

CHAPTER SIX

2. Twenty minutes of flight at 10,000 feet, maximum endurance profile (T-34C = 60 lbs,

T-39N = 540 lbs).

You must choose the greater of these two amounts.

NOTE

In all of your planned flights thus far you have complied with the

VT-10/4 requirements and planned for your alternate profiles from

destination IAF to alternate IAF. OPNAVINST 3710.7 dictates

that you must plan from your destination IAF to alternate airfield.

This is not a discrepancy. In your planning at VT-10, the alternate

IAF is simply an intermediate point and is followed by an

instrument approach to the alternate airfield, thus complying with

the 3710.

Figure 6-1 Concept of Mission Completion Feasibility

Using the example of a flight from NAS Pensacola to Tyndall AFB, we will demonstrate the

concept of Mission Completion Feasibility.

In Figure 6-1, you have computed 545 lbs remaining at the destination initial approach.

Additionally, you planned for an alternate; therefore, fuel planning for the alternate is going to

determine your mission completion fuel.

The EMERGENCY "BINGO" TO ALTERNATE section on the reverse side of the jet log

(Figure 6-2) determines your mission completion fuel, specifically the LAST CRUISING ALT

line. This line meets your OPNAV fuel requirements in it comprises fuel to your alternate IAF,

the fuel for one approach, and the fuel required for reserve. If it becomes necessary, due to

weather conditions or problems at your destination airfield, to proceed to your alternate, this

TOTAL fuel figure is the minimum fuel required to safely and legally do so. In this example, we

have a mission completion fuel of 160 lbs.
