12. A method for supplying fuel from a cryogenic tank of an aircraft to a main turbomachine of the aircraft, the main turbomachine having a setpoint flow rate of fuel, which is according to a movement phase of the aircraft, the method comprising the steps of:
circulating a fuel flow from upstream to downstream in a fuel circuit by means of a pump operating at a predetermined constant speed, the pump providing a nominal supply flow rate by using a supply member,
transmitting calories from a hot source to the fuel flow via a heating circuit, and
emptying a buffer tank, supplied by the fuel circuit, when the setpoint flow rate is higher than the nominal supply flow rate to supply the main turbomachine in parallel with the supply member.
