Automatic Life Saving Device in Commercial Aircrafts using Feedback Control System

Tennyson Samuel John


Several safety devices have filled in the vacuous spaces in commercial airplanes which once did not possess such sophisticated mechanisms. Commercial airplanes have copious amount of instruments and electrical circuits to provide a proper control system inside the plane. A noteworthy invention in the early 80â??s is the oxygen masks provided for every passenger during a plane crash or if the airplane is subjected to climatic disturbances while travelling a passenger manually uses the oxygen masks. The oxygen control system in the airplanes has proved very effective in providing an overall safety to the passengers. But the technique given below is far more advanced than the present scenario. A person suffering from a breathing ailment is succumbed to variations in the carbon dioxide levels. Thereby this CO2 is measured and using a feedback control loop, quick actions can be taken in order to provide quick aid to the ailing patient. These are completely automatic and hence it is advanced than the manual oxygen control system presently used in all commercial aircrafts. At the end of the day saving a life is what a humanistic approach is all about.
