JOINT ADVANCED MULTI-ENGINE T-44A
Every 30 min thereafter: Assuming the cruise power setting has been constant, a fuel flow of 200
lbs/hr/engine for .5 hr results in 100 lbs burned per engine. Subtract 100 lbs from the previous entry's
computed fuel per side to obtain the computed fuel quantity.
Step 8. Compute and record (in the remarks section) the amount of indicated and computed fuel remaining after one
approach (125 lbs) to the on-deck fuel of 530 lbs, ie Total Fuel - 655 lbs (530# on deck + 125# for approach).
2130 - 655 = 1475 lbs
b. Computed: 2232 - 655 = 1577 lbs
This is the amount of fuel available to reach the destination, fly one approach and land with the SOP required
265 lbs per side on the deck.
Step 9. Compute and record the estimated fuel time remaining for both the indicated and computed quantities.
Divide the total fuel remaining by the total cruise power fuel flow to obtain the fuel time remaining.
1475 lbs at 400 lbs/hr = 3.69 hrs or 3+41
b. Computed: 1577 lbs at 400 lbs/hr = 3.94 hrs or 3+56
These times represent the time remaining, at the current fuel flow rate, until 265 lbs per side, including 1 approach.
Step 10. Compute and record the time enroute to the destination. Using the required charts, add up the mileage to
the destination and divide this by your groundspeed (725 nm at 210 knots = 3+27).
Step 11. Compare this estimated time remaining enroute (3+27) to the lower (3+41 assuming worst case) of the two
times (indicated or computed) listed under estimated fuel time remaining. This tells us, based on the current fuel
flow rate and groundspeed, we have 3+27 to get to the destination and 3+41 until 265 lbs per side. Thus, we have
roughly a one quarter hour cushion and should land with approximately 315 lbs per side (worst case).
Step 12. Every 30 minutes, repeat Steps 6 - 11 to continuously monitor flight progress by comparing the enroute
time remaining to the fuel time remaining. ETA ENROUTE must be less than EST TIME TO GO FUEL or you
don't have enough fuel to complete your mission!
