Almost all kind of airplanes have both a main and an auxiliary tank for fuel. It will prevent the airplane gets a lost of fuel during the flight.

Military aircraft maintenance - A new concept.

A substantial maturing of maintenance philosophy has occurred in the air transportation industry with introduction of the modern large wide-body airplanes. Application of that new philosophy in a military environment is both feasible and practical. With due consideration of the large and growing expenditures required for aircraft maintenance, and a desire to reverse unfavorable cost trends, the U.S. Navy has formed a team to design, develop, and implement advanced maintenance plans for two first-line weapon systems. New maintenance plans have been developed and are now being implemented. Early results indicate substantially reduced maintenance cost, better-operating airplanes, and significant improvement in aircraft availability.
