A Eurocopter AS 332 Super Puma, operated by Bristow in offshore oil transport in the North Sea, on April 9 became the first helicopter to be fitted with a second-generation Traffic Alert and Collision Avoidance System (TCAS II). The operator worked closely with equipment manufacturer Rockwell Collins to install the safety system aboard the 21-seat aircraft, with the assistance of Shell Aircraft. Bristow Eastern Hemisphere thus received the first EASA STC of TCAS II for rotary-wing aircraft.

According to Arnold Oldach, a Rockwell Collins marketing manager responsible for traffic and surveillance products, it was widely believed in the industry that helicopters were unsuitable applications for TCAS II: “These aircraft are slow; they do not have good climb rates; antennas would [suffer from rotor interference, presenting placement difficulties].”
