Rockwell Collins says aviation history was made when a Super Puma helicopter equipped with a Rockwell Collins' Traffic Alert Collision Avoidance System (TCAS II) and operated by Bristow Eastern Hemisphere departed from Aberdeen Airport for various Shell installations in the East Shetland Basin. Helicopters now have the same level of enhanced safety that TCAS II already provides fixed wing aircraft. Rockwell Collins worked alongside the Aberdeen-based Bristow with the assistance of Shell Aircraft to install, test and certify TCAS II. The group was able to use Rockwell Collins' existing TCAS-4000 product line for fixed wing aircraft, without making any modifications to the system. This effort resulted in Bristow Eastern Hemisphere receiving the first ever EASA Supplemental Type Certification of TCAS II for rotary aircraft.
