Inspections & maintenance
EMAS ownership means doing regular inspections and maintenance that are necessary to ensure continued compliance, performance and safety of the EMAS system. Being proactive is an important aspect in ensuring the longevity of the Runway Safe EMAS, while identifying issues early on results in reducing the scope and duration of any maintenance efforts lowering the overall ownership cost.
Informal inspections should be carried out as part of the airport’s own routine operational procedures. Runway Safe certified staff performs formal inspections quarterly. The maintenance plan is updated as needed after each formal inspection to ensure optimal performance.
Should an overrun occur, the damaged portions of the bed can easily be repaired without impacting other areas. The damaged area is removed and reconstructed with the same material used at the initial installation. Repair materials can be stored on site or shipped from Runway Safe safety stock.
The runway can be operational within hours after the aircraft has been removed with a partly functional EMAS. The final restoration needs to be done after all material is on site but no later than after 45 days.
The Runway Safe EMAS is designed for all types of climates zones. In many cases the wind from the engines clears away most water and snow reducing the need to clean the EMAS. The beds are also designed with drainage so that water is transported away from the arrestor bed. In the case snow removal is necessary, equipment approved by Runway Safe engineers beforehand may be used.
As each EMAS is individually designed, performance reports might have to be updated as the fleet mix changes over time. Runway Safe offers services for updated compliance.
Performance update – Runway Safe recommends that performance predictions for specific aircrafts are performed on a regular basis, especially when new aircrafts are operating at the airport.
Jet blast verification – The Jet blast effect on the EMAS should be verified when new aircraft types are operating the airport, in particular by take-offs from the location of threshold of the EMAS.
