What are the 3 categories of fuel management?
Takeoff and landing
enroute
secondary
Define takeoff fuel management
Tanks 1 and 4 always contain 500-1000 lbs more fuel than tanks 2 and 4
The main tanks are full, except for fuel used for taxi, takeoff, and climb; but not less than 7060 lbs in tanks 1 and 4, and not less than 6410 lbs in tanks 2 and 3 when the external tanks contain usable fuel
What is enroute fuel management meant to do?
Seeks to maximize the weight in the outboard fuel tanks as long as possible but does not take mission constraints into consideration while doing so
Designed to maintain maximum fuel in the outboard tanks during the enroute phase of flight.
Improves wing-loading and efficiency during long transit legs; it also extends airframe service life, especially with medium to heavy cargo loads.
Define enroute fuel management
When the ext and/or aux tanks contain usable fuel, tanks 1 and 4 are maintained at a max fuel level of 8310 and contain 500-1000 lbs more fuel per tank than tanks 2 and 3
When ext and/or aux tanks do not contain usable fuel, tanks 1 and 4 are maintained at a max level of 8310 while tanks 2 and 3 are reduced to a level of 1520. Fuel from 1 and 4 will then supply the motors until all main tanks reach a level of 1520. When all main tanks reach 1520, establish direct tank-to-engine feed.
