The purpose of this Safety Enhancement is to reduce the rate of unnecessary Traffic Alert and Collision Avoidance System (TCAS) alerts due to current TCAS alerting parameters. A study will be conducted to determine how best to reduce or eliminate the number of TCAS alerts between Instrument Flight Rules (IFR) and Visual Flight Rules (VFR) traffic in situations with adequate Air Traffic spacing. If safety case study meets current Federal Aviation Administration (FAA) acceptability standards, a Technical Standard Order (TSO) will be developed to provide for more accurate alerting.
