TCAS II ON HELICOPTERS

摘要

A traffic collision avoidance system (TCAS) II has been standard equipment on fixed-wing aircraft for manyrnyears and is justifiably regarded as a safety enhancement. Larger helicopters often operate IFR and until now have not been afforded the same protection as the general belief was that TCAS II would not work on helicopters as they were too slow and lacked the required climb performance.
