3. Introduction
Aircraft hijacking is the unlawful seizure of an aircraft by an individual or a group. In most cases, the pilot is forced to fly according to the orders of the hijackers.
WikiPedia

4. Introduction

5. Aim
To Develop and demonstrate a proof of concept system that prevents aircraft hijacking
This system is based on RFID technology

6. Survey What shall we do in the present case?

30. Conclusions
• 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 have 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 the integration
of them later.
• the system is shown to work based on the concept described above

31. Future plans
The system does not include other controls such as engines and auto pilot. it should be attempted to include them in future
This is a proof of concept work and this has to be developed in prototype scale in future
