The aim of this study is to provide a reference document on current risks and proposed reductions for smoke and fire incidents in commercial transport aircraft. The screen printing technique was used as the gas sensor production technique for the produced sensor with tin oxide was used as metal oxide in the produced samples. The samples produced were examined under the gases with specified gas detecting properties, and it was concluded that they can be used simultaneously with smoke detectors in order to increase the detection reliability and reduce the alarm time with the smoke detectors currently used in today's passenger aircraft.
When the electrical characteristics of the sensor made were examined, it was observed that it meets the requirements of the FAA and European Aviation Safety Agency (EASA) standards (the fire should be detected within one minute) and the false alarm situation experienced in the smoke sensors used today can be eliminated.
It was observed that dozens of aircraft changed their planned flights, due to the high level of false warnings given by the smoke detectors used in the airplanes and this resulted in financial losses.
There is no other sensor other than smoke detectors used for fire detection in aircrafts. With this study, the gas detecting feature of the produced samples was examined under the specified gases, and it was concluded that they can be used simultaneously with smoke detectors to increase detection reliability and reduce alarm time with the smoke detectors currently used in today's passenger aircraft.
