L.T.A.S. Landing and Take-off Assistance System - System

 

A motorised platform guided by radar and intended to be placed under an aircraft without intervention by the navigating personnel.

 

Once the platform is in position, a descent signal is transmitted as well as altitude data relative to the landing surface. An aircraft which encounters technical failure with its on board landing system may therefore be landed without damage. In the long term, landing operations will become possible totally based on instruments. Once set down on the platform, the wheels are blocked with chucks and the motors are switched over to generator mode. The kinetic energy produced is then recovered and transformed into electricity.

 

The on-board computer programs deceleration until the unloading point is attained using electromagnetic brakes, this deceleration and stopping mode provokes no wear on the aircraft’s braking system or tyres thus providing a cost saving aspect.

 

 The rails, maintained frost-free with a chimical or heating-element system, guarantees availability of the airport runway all year round. At take-off, the propulsion system shortens the take-off distance. The platform accompanies the aircraft during the meters of actual take-off in case of a possible bounce and thus offers the possibility to stop in case of an aborted take-off. The rails are embedded and flush with the runway surface thus allowing it to be used as previously while increasing the take-off and landing capacity.

 

Passenger comfort is increased. Noise and fuel pollution is considerably reduced: 800 litres of kerosene saved every one and a half minutes, - 77% of accidents (51% during landing, 21% during take-off, 5% during taxiing) will be saved.
