Auxiliary Control Stand

Fuel System

  1. Auxiliary Fuel Pump Switches
    Toggles the auxiliary fuel pumps (electric) for the main tanks. For engine start, the fuel pumps must be HIGH or LOW, during takeoff or in emergency situations, in position HIGH (for details, refer to the Checklist).
    [FS: electrical fuel pumps are turned on with positions LOW or HIGH and turned off in position OFF.]
  2. Auxiliary Fuel Pump Switches (Inboard and Center Section Tanks)
    Before Tank 5, Tank 6 or Tank 7 can be emptied, its fuel pump switch must be positioned HIGH or LOW. See also (4).
  3. Fuel Cross-feed Lever
    Toggles the cross-feed valve of the corresponding fuel tank, allowing any engine to draw from any tank. For working cross-feed, the Fuel Cross-feed Levers of both, the receiving engine(s) and the supplying tank, must be OPEN. Additionally, the Fuel Tank Lever (59) on the Flight Engineer's Panel of the supplying tank must not be OFF.
    Cross-feed from one wing side to the other is possible, too, but only with the Fuel Cross-over Lever (5) in position OPEN.
    [FS: By default, the Fuel Cross-feed Levers are CLOSED.]
     
    Example: Connecting the left engines to No. 1 and the right engines to No. 4:
    a. Open the Fuel Cross-feed Lever (3) of the receiving engines #2 and #3.
    b. Open the Fuel Cross-feed Lever (3) of the supplying tanks #1 and #4.
    c. Start fuel cross-feed by closing the Fuel Tank Selector Levers (59) on the Flight Engineer's Panel of the receiving engines #2 and #3.
     
    Example: Connecting the left engines to No. 2 and the right engines to No. 3:
    a. Open the Fuel Cross-feed Lever (3) of the receiving engines #1 and #4.
    b. Open the Fuel Cross-feed Lever (3) of the supplying tanks #2 and #3.
    c. Start fuel cross-feed by closing the Fuel Tank Selector Levers (59) on the Flight Engineer's Panel of the receiving engines #1 and #4.
     
    General notes on the fuel system:
     
    The initial model 049 had four fuel tanks named Tank 1 (for the left outboard engine), Tank 2 (engine #2), Tank 3 (engine #3), Tank 4 (right outboard engine). Also refer to the Fuel Tank Indicators (29), (30), (31) and (32) on the Flight Engineer's Panel.
    Model 1649A had extra fuel in three additional tanks, named No. 5, No. 6 and No. 7 (see (5), (6), (7) on the Upper FE Panel and (4).
    When using the FS fuel and payload menu, it is important to know, which of the tank names displayed in the menu correspond to which tank in the L-1649A Starliner fuel system.
     
    FS tank assignments (AIRCRAFT.CFG) for model 1649A:
     
      Tank 1649A
    Name
    FS2004/FSX
    Name
    Capacity
    in lbs. (gal)
      Left outboard No. 1 External1 8064 (1344)
      Left middle No. 2 LeftMain 8310 (1385)
      Left inboard No. 5 Center2 8220 (1370)
      Center section No. 7 Center1 9876 (1646)
      Right inboard No. 6 Center3 8220 (1370)
      Right middle No. 3 RightMain 8310 (1385)
      Right outboard No. 4 External2 8064 (1344)

    When calculating the amount of fuel needed, ensure, that the maximum landing weight (123,000 lbs) will never be exceeded. When doing only a pattern, you may choose this value as takeoff weight (see L-1649A Specifications).
     
    Recommended order of usage (typical):
     
      Engine #1 #2 #3 #4   Fuel Usage Procedure
      Tank 1 2 3 4   Use 810 lbs. from each tank
      Tank 1 7 7 4   Until No. 7 is empty (or next row)
      Tank 7 2 3 7   Until No. 7 is empty
      Tank 5 5 6 6   Until all fuel except 900 lbs. per tank is used
      Tank 1 5 6 4   Until No. 5 and 6 are empty (or next row)
      Tank 5 2 3 6   Until No. 5 and 6 are empty
      Tank 1 1 4 4   Until total fuel in No. 1 and 4 equals total in
      No. 2 and 3 (or next row)
      Tank 2 2 3 3   Until total fuel in No. 2 and 3 equals total in
      No. 1 and 4
      Tank 1 2 3 4   End of flight and landing

    [FS: If a flight situation is saved and reloaded later, all Fuel Tank Selector Levers (59) on the Flight Engineer's Panel will be in their default positions, which is OPEN for levers 1 and 4 and POS. 2, POS. 3 for levers 2 and 3, and all Fuel Cross-feed Levers (3) are CLOSED, causing all engines to draw from their main tank. Due to the limitations of the FS fuel system, it is not possible to properly restore the correct position of each fuel tank selector (FS does not save the positions of more than two fuel selectors)].
     
    To avoid that one or more engines run out of fuel due to an improperly operated fuel system, follow these steps when configuring the fuel system using the Fuel Tank Selector Levers (59) on the Flight Engineer's Panel and the Fuel Cross-feed Levers (3):
    1. Set all Fuel Tank Selector Levers to their default position (all engines draw from their main tanks).
    2. Move the Fuel Cross-feed Levers (3) to the desired positions.
    3. Start fuel cross-feed by closing the Fuel Tank Selector Levers of the receiving engines.
     
    [FS: The illustration of the fuel system displayed on the Fuel Pump Switches Panel contains many quick tip mouse areas (ie. the engine and valve symbols), giving you detailed information about the current configuration.
    Each time the fuel configuration is changed (ie. by toggling the fuel pumps or by opening or closing the fuel tank valves or cross-feed valves), there will be a small delay, until the changes become effective. For example, this simulates that an engine which is cut off from any fuel, will not immediately shut down, because there is still a small amount left in the fuel lines, which can be consumed until running out of fuel. This also is giving you a small amount of time to correct your settings, if necessary.]
  4. Center Fuel Tank Selector Levers
    Both levers have three positions, OFF, POS. 7, POS. 5 and OFF, POS. 7, POS. 6, selecting (for each wing side) either the inboard or the center section tank.
    [FS: By default, the levers are in position OFF.]
     
    Example: Do following steps to set left and right outboard engines to No. 7:
    a. Set both Center Fuel Tank Selector Levers to position POS. 7 (middle).
    b. Open the Fuel Cross-feed Lever (3) of the receiving engines #1 and #4.
    c. Position Tank 7 Fuel Pump Switch (2) to HIGH or LOW.
    d. Close the Fuel Tank Selector Levers (59) on the Flight Engineer's Panel of the receiving engines.
     
    Example: To connect the left engines to No. 5 and the right engines to No. 6:
    a. Set left Center Fuel Tank Selector Lever to position POS. 5 (down).
    b. Open the Fuel Cross-feed Lever (3) of the receiving engines #1 and #2.
    c. Set right Center Fuel Tank Selector Lever to position POS. 6 (down).
    d. Open the Fuel Cross-feed Lever (3) of the receiving engine #3 and #4.
    e. Position Tank 5 Fuel Pump Switch (2) to HIGH or LOW.
    f. Position Tank 6 Fuel Pump Switch (2) to HIGH or LOW.
    g. Close all Fuel Tank Selector Levers (59) on the Flight Engineer's Panel.
     
    Example: Setting engine #2 to No. 5 and engine #3 to No. 6:
    a. Set left Center Fuel Tank Selector Lever to position POS. 5 (down).
    b. Set right Center Fuel Tank Selector Lever to position POS. 6 (down).
    c. Open the Fuel Cross-feed Lever (3) of the receiving engines #2 and #3.
    d. Position Tank 5 Fuel Pump Switch (2) to HIGH or LOW.
    e. Position Tank 6 Fuel Pump Switch (2) to HIGH or LOW.
    f. Position the Fuel Tank Selector Levers (59) on the Flight Engineer's Panel of the engines #2 and #3 to OFF.

  5. Fuel Cross-over Lever
    In case of emergency, the main fuel cross-over valve may be opened for fuel transfer from one wing side to the engines of the other wing. By default, the valve is closed and can be opened by moving this lever down. See also (3).
