Class A Airspace ACAS Reporting Revised
New requirements narrows scope of ACAS resolution advisory reports.

The NTSB issued a direct final rule to narrow the focus of its Part 830 notification requirement concerning certain Airborne Collision and Avoidance System (ACAS) conflict resolution advisories issued to an aircraft operating in Class A airspace. Currently, all ACAS advisories within Class A airspace are required to be reported.
