Runway Vacated Detector

 (fatal crash EKRK – ASW Runway Vacated could have prevented it).

Runway occupancy times are a critical factor in determining runway capacity at peak traffic times. This configuration and application enables the airport to detect if anything has left the runway exit point.

At times of high levels of arriving traffic, airports may be able to use this technology to increase throughput. Whilst it does not reduce runway occupancy time it reduces the time required to report the runway clear since it provides instantaneous and precise position reports.

The ability to determine whether or not the tail of an aircraft is clear of the runway, and thereby no longer presenting an obstacle, is therefore of particular importance in achieving optimum utilisation.

Modern aircraft use technologies like Airbus “Brake to Vacate” an innovative braking system that delivers significant improvements in runway efficiency since it enables a safe braking of the aircraft to vacate on a certain runway exit.

However it is technology dependent and only equipped in modern aircraft. With ASW barrier technology benefits can be made for aircraft with any performance capability since its advantage is in the exact report and reduced delay time.

An aircraft can be cleared as vacated from the runway in a quicker and safer way than using other surveillance based technologies. In order to determine a ‘common’ safe clearance value, the largest of the aircraft that most commonly operate to/from the airport will be accounted for.
