Disclosed is a method for controlling the flammability of fuel vapors in an aircraft main fuel tank that is located in whole or in part in the fuselage contour. The method comprises a fuel system architecture and fuel consumption sequencing maintaining liquid fuel in said main tanks during all normal operations. Ceasing the withdrawal of fuel from the main tank when the fuel reaches a predetermined level thereby limiting the volume and flammability exposure time of the fuel vapor ullage. Once the predetermined level is met the fuel is supplied from wing ...
1. A method for controlling the formation of flammable vapors in an aircraft main fuel tank located in whole or in part in the fuselage contour wherein each wing includes a main fuel tank, a wing tank outboard of the main fuel tank and a collector tank disposed within the main fuel tank that is in fluid communication with the wing tank; the method comprising: (a) initially consuming fuel in the main tank until the fuel quantity has reached a predetermined reserve level;(b) sensing that the fuel has reached the predetermined level;(c) initiating the opera...
