I use the following procedures and settings with regard to fuel management:
Refueling: 1. Load all 4 main tanks equally. 2. After 1 and 4 main tanks are full, continue to load 2 and 3 main tanks. 3. After all main tanks are full, load reserve tanks. 4. After all wing tanks are full, load the center tank. Preflight Preparation: Fuel System TEST & SET - Fuel Quantity Gauges TEST - Boost Pumps TEST - Tank No. 2 Aft Boost Pump Switch ON - All Crossfeed Selectors OPEN - Reserve Tank Fuel Transfer Selectors CLOSE - Fuel Temperature Selector CHECK & NO. 1 TANK - Fuel Heat Switches OFF Before Engine Start: Fuel System SET FOR START * “Tank to Engine” Configuration: - One Boost Pump Switch in tanks No. 1, 2, 3 & 4 ON - Center Tank Boost Pumps OFF - Crossfeed Selector No. 1 OPEN - Crossfeed Selectors No. 2, 3 & 4 CLOSE Taxi-out: Fuel System SET FOR TAKEOFF * If Center Tank empty or less than 20,000 lbs : ->(“Tank to Engine” Configuration): - One Boost Pump Switch in tanks No. 1, 2, 3 & 4 ON - Center Tank Boost Pumps OFF - Crossfeed Selectors No. 1 OPEN - Crossfeed Selectors No. 2, 3 & 4 CLOSE * If Center Tank exceeds 20,000 lbs -> “Center Tank to Outboard, Main Tanks to Inboard Engines” Configuration: - One Boost Pump Switch in tanks 1, 2, 3, 4 & Center ON - Crossfeed Selectors No. 2 & 3 CLOSE - Crossfeed Selectors No. 1 & 4 OPEN Cruise: Check every 20 minutes the following set of conditions and act appropriately: * If Center Tank exceeds 20,000 lbs and less than 12,000 lbs of total fuel consumed ->”Ctr Tank to Outbd.
