How much fuel does a 747 jumbo jet carry?

The amount of fuel is in pounds on U.S. aircraft and metric units on European aircraft.  Keep in mind each models from the 747-100, -400, -SP and –SR series will hold a different amount of fuel in pounds depend on the aircraft design.

In accordance with the type certificate data sheet (TCDS A20WE) for the B-747 all models the following fuels are allowed.

The following fuels are eligible for Pratt and Whitney engines: JP-1, JP-4, and JP-5 fuels conforming to the P&WA Specification No. 522E or later revision may be used separately or mixed in any proportion without adversely affecting the engine operation or power output. No fuel control adjustment is required when switching fuel types.

G.E. engines use fuels conforming to G.E. Spec. D50TF2. MIL-T-5624, Grades JP-4 or JP-5, and ASTM D1655, Jet A, Jet A1, and Jet 8 are consistent with G.E. Specifications. [JP-8 is also approved for use in CF6-80C2 Series engines.] CF-80C2 series engines incorporating Dribble Flow Fuel Nozzles PN 9331M72P33, P34 and P41 are prohibited from the use of JP-4 and Jet B (wide cut) fuel.
