The FAA has issued new rules governing how airplanes and helicopters operate while close by—a major focus for aviation regulators since the fatal collision of an American Airlines jet and a U.S. Army Black Hawk helicopter over Washington, D.C., last year.
A general notice announced Wednesday suspends the use of visual separation between airplanes and helicopters in Class B and Class C airspace, and Terminal Radar Service Areas (TRSAs). Class B airspace surrounds some of the largest and busiest airports in the U.S., while Class C airspace generally covers medium-sized airports.
