Hijack-proof piloting
A hijack-proof piloting system for airliners is being developed to prevent terrorists hijacking the planes.
The mechanism is designed to make it impossible to crash the aircraft into air or land targets – and enable the plane to be flown by remote control from the ground in the event of an emergency.
Scientists at aircraft giant Boeing are testing the tamper-proof autopilot system which uses state-of-the-art computer and satellite technology.
It will be activated by the pilot flicking a simple switch or by pressure sensors fitted to the cockpit door that will respond to any excessive force as terrorists try to break into the flight deck.
Once triggered, no one on board will be able to deactivate the system. Currently, all autopilots are manually switched on and off at the discretion of pilots.
After it has been activated, the aircraft will be capable of remote digital control from the ground, enabling operators to fly it like a sophisticated model plane, manoeuvring it vertically and laterally.
A threatened airliner could be flown to a secure military base or a commercial airport, where it would touch down using existing landing aids known as 'autoland function'.
After it had landed, the aircraft's built-in autobrake would bring the plane safely to a halt on the runway.
This will use tiny cameras linked to specialist computers to record every twitch, blink, facial expression or suspicious movement made on board flights in order to identify potential terrorists.
