The invention relates to a method for operating an aircraft cooling system (10), comprising the steps guiding a cooling medium through a cooling circuit (26) which is coupled to a refrigerating machine (12) and to at least one cooling energy consumer (14a-14d) in order to supply cooling medium cooled by the refrigerating machine (12) to the cooling energy consumer (14a-14d), and controlling the operation of the refrigerating machine (12) by a control unit (42), such that coolant medium cooled by the refrigerating machine (12) to a predetermined cooling medium flow temperature is supplied to the cooling energy consumer (14a-14d). The method for operating an aircraft cooling system (10) further comprises detecting a cooling energy requirement of the cooling energy consumer (14a-14d) and transmitting a signal indicative of the cooling energy requirement of the cooling energy consumer (14a-14d) to the control unit (42). The operation of the refrigerating machine (12) is controlled by the control unit (42) in such a way that cooling medium which is guided through the cooling circuit (26) is cooled to a cooling medium flow temperature which is adapted to the cooling energy requirement of the cooling energy consumer (14a-14d).
