Lockheed L-049A Constellation

- Auxiliary Fuel Pump Switches
Toggles the auxiliary fuel pumps (electric). 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]
- Auxiliary Fuel Pump Switches for 2A/3A Tanks
Model 149 was fitted with additional fuel tanks for the inboard engines (tanks 2A and 3A).
In case of the 049, these switches are inactivated. See also (1).
[FS: If a 149 is simulated, switch 2A has the same effect than switch 2, and 3A the
same as switch 3.]
- Emergency Shut-Off
Setting this switch to OFF closes the fuel valve and causes the corresponding
engine to be cut off from any fuel tank. An engine won't start, if its
Emergency Shut-Off Switch is set OFF.
[FS: Click to open the protection cover. Then, each click toggles the switch ON/OFF. The
cover closes automatically after some time.]
- Fuel Transfer Lever
Toggles the crossfeed valve of the corresponding fuel tank. For working
crossfeed, the Fuel Transfer Levers of both, the receiving engine and
the supplying tank, must be OPEN. Additionally, the Fuel Tank Lever (5)
of the supplying tank must be in position OPEN.
[FS: By default, the crossfeed levers are CLOSED]
- Fuel Tank Lever
Toggles the tank valve of the corresponding fuel tank. If a Fuel
Tank Lever is OPEN, the corresponding engine is always
drawing its fuel from that tank, regardless of the position of the
Fuel Transfer Levers (4). An engine is cut off from any fuel, if
its Fuel Tank Lever and its Fuel Transfer Lever (4) is
CLOSED.
[FS: By default, these levers are in position OPEN]
General notes to the fuel system: Model 049 has four fuel tanks named
Tank 1 (for the left outboard engine), Tank 2 (left inboard),
Tank 3 (right inboard), Tank 4 (right outboard). Also refer to the
Fuel Tank Indicators (28), (29), (30) and (31) on the
Flight Engineer's Panel.
PLEASE NOTE: When using the FS2004 fuel and payload menu,
it is important to know, which of the tank names displayed in the menu
correspond to which tank in the 049/149 fuel system:
Engine |
049/149Tank Name |

Tank 1 |

#3 (right inboard) |
Tank 3 |
Right Main |

#4 (right outboard) |
Tank 4 |

Model 149 is fitted with two additional tanks 2A and 3A for the
inboard engines:
#2 (left inboard) |
Tank 2A |
Left Aux |
565 |
#3 (right inboard) |
Tank 3A |
Right Aux |
565 |
[FS: Don't be confused about the fact that the FS2004 center tanks are
used as outboard tanks and not as fuselage tanks. This has been done to implement
a very realistic fuel utilization, especially in case of the 149.]
[FS: With opened Fuel Tank Lever 2, Tank 2A is emptied before Tank 2,
and with Fuel Tank Lever 3 open, Tank 3A is emptied before Tank 3
(FS2004 auto crossfeed).]
When calculating the amount of fuel needed, ensure, that the
maximum landing weight (77,800 lbs) will never be exceeded. When doing
only a pattern, it is a good idea, to choose this value as takeoff weight,
too (see 049A Specifications).
[FS: If a flight situation is saved and reloaded later, all Fuel Tank Levers (5)
will be in position OPEN and all Fuel Transfer Levers (4) are
CLOSED, causing all engines to draw from their default tank. Due to the
limitations of the FS2004 fuel system, it is not possible to properly restore
the correct position of each fuel tank selector (FS2004 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 Tank Levers (5)
and Fuel Transfer Levers (4):
1. Set all Fuel Tank Levers (5) to position OPEN (all engines draw
from their default tank).
2. Move the Fuel Transfer Levers (4) to the desired positions.
3. Start fuel crossfeed by closing the Fuel Tank Levers (5) of the
receiving engines.
[FS: The illustration of the fuel system displayed on the Fuel Panel
contains many quick tip mouse areas (ie. the engine and valve symbols),
giving you detailed information about the current configuration.]
