EMAS - gefundenes fressen for Norge?



USA`s FAA synes å være på glid når det gjelder bruken av Engineered Materials Arresting System, et system som har stoppet 7 fly fra å gå av beneenden. Dette er en masse som flyet kjører inn i og stopper uskadd etter få meter. Etter anmodning fra undertegnede har jeg mottatt følgende forklaring på status:
Here is a copy of the latest FAA fact sheet dated 7-3-2011.

As for the FAA Policy that establishes EMAS = 1000 ft; please refer to attached FAA Order 5200.9 "FINANCIAL FEASIBILITY AND EQUIVALENCY OF RUNWAY SAFETY AREA IMPROVEMENTS AND ENGINEERED MATERIAL ARRESTING SYSTEMS".
This is guidance for (a) comparing various runway safety area (RSA) improvement alternatives with improvements that use Engineered Material Arresting Systems (EMAS); and (b) determining the maximum financially feasible cost for RSA improvements, whether they involve EMAS or not.
This guidance uses a standard EMAS installation (70 knot overrun protection for the fleet mix with 600 ft for undershoot protection) as a benchmark for comparing and determining the best financially feasible alternative for RSA improvements. It should be used for improving deficient safety areas, for new runway projects when comparing the costs of providing a standard RSA to the costs of installing EMAS. It may also be used to justify decreasing the dimensions of existing RSAs in connection with runway extension projects (taking 1000 ft RSA done to 600 ft on each end of runway, installing EMAS and gaining an 800 ft runway extension).
FAA uses 1000 ft runway safety areas (305 m), while ICAO recommends 240 m RESA beyond 60 m runway strip (providing 300 m overrun protection).
Systemet vil bli nærmere forklart på Flyoperativt Forum kl 0900 den 4. mai. Sjekk ut FAA`s Fact Sheet på http://tinyurl.com/6al6qmh
