JetCorp of St Louis, Missouri, has received US Federal Aviation Administration supplemental type certification for the installation of AlliedSignal's CAS 66A traffic-alert collision-avoidance system (TCAS I) on a Bell 412 helicopter. The TCAS antennas were mounted on both the upper-transmission cowling and tail boom to avoid interference from the wirestrike kit above the cockpit. In the Bell installation, the TCAS can be operated as a single traffic/ vertical-speed indicator (TA/VSI), or a dual TA/VSI. An optional graphics-interface unit is also available.
