icing conditions

Weather conditions conducive to the formation of ice on an aircraft in flight. These conditions are usually characterized by visible moisture in the air and temperatures around the freezing level (i.e., +2° to −10°C). Pilots encountering icing conditions are urged to issue a pilot weather report (PIREP) immediately.

The response was unfortunate: "flying through clouds at an altitude that is near or below freezing would constitute flight into known icing conditions." Furthermore, the flight would be "a violation whether the aircraft accretes ice or not." There you have it.
This is the first time that 3D shapes have been modeled to analyze their propensity to experience icing conditions during flight.
I received a call from the owner of a turbocharged, high-performance single who lives in the Great Lakes region, well-known for icing conditions in late autumn, winter and early spring.
At Aviation Week Network's 16th Annual Program Excellence Awards banquet last night, a team from UTC Aerospace Systems' Sensors & Integrated Systems business was honored for the company's groundbreaking achievements in improving aviation safety in severe icing conditions, the company said.
In response to the new regulations, Canada's National Research Council (NRC) has upgraded its altitude icing wind tunnel--one of the few in the world that can simulate and test aircraft surfaces, components and probes in icing conditions at altitude.

Buses and vehicles were blocking the road - the result of icing conditions and lack of initiative on the part of those responsible for keeping the roads clear.
FAA and other aviation stakeholders have undertaken many efforts to improve safety in icing conditions. For example, in 1997, FAA issued a multiyear plan for improving the safety of aircraft operating in icing conditions and has since made progress on the objectives specified in its plan by issuing regulations, airworthiness directives, and voluntary guidance.
The fix involves installing a new stall warning protection computer with updated logic that assigns a particular stall speed buffer for each flap setting to be used in icing conditions or for when a flap system failure is detected.
He also pointed to the flight manual of the airplane, a Bombardier Q400 turboprop, which calls for pilots to shut off the system in "severe" icing conditions, but Chealander stopped short of saying the pilots acted improperly by activating the system.
