SYSTEM FOR CONTROLLING THE FEED AIR TEMPERATURE OF A PASSENGER AIRCRAFT

摘要

A system for controlling the temperature of feed air supplied to a cabin area of a passenger aircraft (10) includes a temperature sensor system (24), by means of which a representative reading can be taken for an ambient temperature in the cabin area, and an evaluation and control unit (26) associated with the temperature sensor system (24) which is provided in order to control the temperature of the feed air, dependent upon a deviation of the ambient temperature reading in relation to an ambient temperature optimum value. The temperature sensor system (24) includes at least one sensor series which extends along the length of the cabin area, which is activated by an activation signal to give a response signal which contains information on temperature for various points along the sensor series. The sensor series (24), which can essentially extend through the whole cabin of the aircraft (10), can for example, be in the form of a fibre optic cable activated by laser light impulses.
