Method for controlling the temperature of feed air injected into the cabin zone of a passenger aircraft

Method for controlling the temperature of feed air injected into at least one cabin zone of a passenger aircraft, the temperature of injected feed air being controlled for each cabin zone dependent on the deviation of the injection temperature actual value of the feed air from an injection temperature target value, the injection temperature target value being established using an external ambient temperature actual value and not using a temperature sensor in the at least one cabin zone.
