A retrofit contract signed with the German Federal Police calls for retrofits to be performed through to 2010 on the agency’s fourteen EC155s. The Eurocopter maintenance center in Kassel- Calden, Germany has already retrofitted four of the EC155s, equipping the helicopters with an Airborne Collision Avoidance System (ACAS), reinforced flooring, and a four-channel audio warning system with speech synthesis. The aircraft have also received a new “police blue” livery, and the video system architecture has been upgraded to include images from the FLIR on the 4.5-inch SMD(1) Primary Flight and Navigation Display screens. The Kassel-Calden maintenance center is qualified to work on the entire Eurocopter range, and has received the EASA Part 145 certification. Its highly motivated and qualified team of specialists already has extensive experience working on the EC155: The operator DanCopter entrusted the center with the task of modernizing and installing new equipment on its fleet of EC155s.
