This document describes the data collection methodology, and the results obtained from the Traffic Alert and Collision Avoidance System TCAS user Survey. The survey was conducted during the fall, spring and early summer of 1984. The survey examined helicopter operator and pilot responses in three particular areas of interest 1 The nature of helicopter Near Mid-Air Collision NMAC encounters 2 Pilot Display Preferences and 3 User price thresholds for a helicopter TCAS. The survey revealed that only a small percentage of near mid-air collisions involving helicopters are reported, although pilots assert that mid-air collisions pose a significant hazard to flight safety. This report contains breakdowns, by operator group, of significant characteristics of helicopter operations and their associated NMAC hazards which should be addressed in the design of a helicopter specific TCAS.
