Fuel measurement for vertical take-off dual-engine aircraft

A method for redistributing fuel in an aircraft, comprising:

• determining a first fuel level in a first nacelle fuel tank, wherein the first nacelle fuel tank is configured to provide a supply of fuel to a first engine during both (i) a vertical take-off and land operation and (ii) a horizontal flight operation;
• determining a fuselage fuel level in a fuselage fuel tank;
• and
• determining whether to redistribute the fuel across at least the first nacelle fuel tank and the fuselage fuel tank based at least in part on the first fuel level and the fuselage fuel level, wherein a low-pressure fuel pump is configured to cause the fuel to be distributed from the fuselage fuel tank to one or more of the first nacelle fuel tank and a second nacelle fuel tank, and wherein a bypass valve between the fuselage fuel tank and one or more of the first nacelle fuel tank and the second nacelle fuel tank is configured to be opened or closed at least based on the determination of whether fuel is to be redistributed.

A computer program product embodied in a non-transitory computer readable medium for redistributing fuel in an aircraft, and the computer program product comprising computer instructions for:

• determining a first fuel level in a first nacelle fuel tank, wherein the first nacelle fuel tank is configured to provide a supply of fuel to a first engine during both (i) a vertical take-off and land operation and (ii) a horizontal flight operation;
• determining a fuselage fuel level in a fuselage fuel tank;
• and
• determining whether to redistribute the fuel across at least the first nacelle fuel tank and the fuselage fuel tank based at least in part on the first fuel level and the fuselage fuel level, wherein a low-pressure fuel pump is configured to cause the fuel to be distributed from the fuselage fuel tank to one or more of the first nacelle fuel tank and a second nacelle fuel tank, and wherein a bypass valve between the fuselage fuel tank and one or more of the first nacelle fuel tank and the second nacelle fuel tank is configured to be opened or closed based on the determination of whether fuel is to be redistributed.
