Development and Testing of Anti Hijacking System for Civil Aircraft

Abstract

A proof of concept system is developed and demonstrated to prevent hijacking attempt of aircraft. The system is mainly based on Raspberry Pi PC and the control program is written in the scripting language Python. The system will disable manual control of the aircraft, if a particular condition is met persistently beyond the predefined time limit. The condition to be met is simultaneous detection two authorised RFID tags for more than a predefined time period of 10 seconds. The system is seen to be operated till the time period of 10 seconds and becomes inoperative and is seen to take control of aircraft by triggering auto pilot beyond 10 seconds. The system will not allow any manual input such as disabling the system since this can result in vulnerability. As a part of the literature survey is carried out to get details of other anti-aircraft hijacking systems explored in the past. As seen in the literature survey, all the proposed mechanism has a drawback of either operating from the cabin or a possibility to disable the system manually. Two RFID sensors and tags, two servos and one joy stick were used in this work. The system is developed by developing the individual systems first followed by the integration of them later. The system is shown to work based on the concept described above.
