![]() ![]() ![]() Cut-away of Runway Safe EMASMAX® block (Image from Runway Safe website) EMAS Blocks being unloaded after delivery to LCYĪt the Western end of the runway the existing safety zone was extended on to a previously grassed area which required the preparation of a new asphalt surface on to which the EMAS blocks could be installed but that site isn’t easily viewable from public areas so this post focuses on works at the Eastern end of the runway. Care also had to be taken to ensure that the runway approach lights were not obstructed by the new surface and access for maintenance works was still possible. The installation process involved the construction of new areas of asphalt surface on to which stacked layers of the EMAS material sandwich blocks were placed and bonded together. The works have taken place during the airport’s closure periods due to the need for access to the live runway and it took place over the Winter period of 2022/3. The prime contract for the works was awarded to blu-3 and makes use of the Runway Safe EMASMAX® system. Previously LCY had paved Runway End Safety Areas (RESA) that served that same purpose but as larger aircraft are planned to operate from the airport an enhanced solution that fitted in the available space was required. The solution has been on the market for over 20 years and has seen most installations at airports within the USA but is being used in more locations where there is limited space and water or other obstacles are located at the airport boundary. In what is believed to be a first for a major UK Civil Airport (RAF Northolt has had a similar solution in place for a few years) London City Airport has installing what is known as an Engineered Material Arresting System (EMAS) at both ends of it’s runway.Īn EMAS system is the equivalent of a gravel trap that will bring an aircraft to a complete stop in a short distance in case of a brake failure or other over-run situation in either landings or aborted take-offs. ![]() The latest enhancement provides both improved levels of operational safety but also facilitates the introduction of additional next-generation aircraft types to the airport’s approved list. London City Airport has an ongoing development programme ( CADP) that seeks to deliver a range of operational and customer improvements to the working of the airport. ![]()
