FIELD: aviation.
SUBSTANCE: method for additional power supply to the aircraft includes application of an auxiliary power unit (APU) (2) in emergency mode to supply auxiliary power to vital aircraft systems. The combustion chamber (21) of the APU (2) is provided with auxiliary fuel (6) from the special source (51) on an independent and separate circulation, at least in part, associated with the special source (52), from the basic circulation (3). As common fuel (4), kerosene is used, and hydrogen, directly stored in solid, liquid or gaseous state in the special source (51), is used as auxiliary fuel (6).
EFFECT: invention reduces the aircraft weight.
