FAA proposes tougher icing rules for new airliner models

Federal air-safety regulators on have proposed tougher rules that would require all new airliner models to demonstrate they can operate safely through a wider range of icing conditions than previously mandated, Dow Jones reported.

The Federal Aviation Administration, among other things, wants future testing of certain models to specifically indicate whether they can fly safely through freezing rain and drizzle, hazardous icing conditions known as "supercooled large drops."

The proposal also would extend more-stringent icing-certification requirements to engines, certain engine parts, and outside airspeed indicators and other sensors.

The document released by the agency follows nearly 16 years of scientific research and analysis focused on icing hazards The proposed rules also require demonstration of the ability to fly safely through ice crystals, and a mix of crystals and freezing rain or drizzle.
