Airmets called for moderate icing
conditions below 12,000 feet msl and an Indianapolis Center statement warned of occasional moderate rime and mixed icing between 2000 and 5000 feet msl.
And they still have an AIRMET for icing over the area, and that runs from Great Falls to Idaho Falls, and that says moderate icing
between the freezing level and 20,000.
We also encountered moderate icing
, with about a quarter of our windscreen getting rapidly covered with ice.
Pilots told us that in moderate icing
or freezing rain, the wings often carry slushy areas or spots of ice that may or may not pop off in flight.
This made it plenty ripe for moderate icing
conditions in that altitude window.
Reporting stations along the flight path advertised widespread marginal VFR and Airmets had been issued for moderate icing
, mountain obscuration and moderate turbulence, and wind shear.
A full series of Airmets were current for the timeframe and intended route of flight, including for moderate icing
, mountain obscuration and low-level windshear, and turbulence.
is indicated by an orange "U" with two vertical lines through it.
An Airmet for moderate turbulence below 8000 feet, and moderate icing
between the freezing level and 22,000 feet were valid.
Our descent immediately brought us into moderate icing
and moderate turbulence.
An Airmet issued prior to the airplane's departure called for moderate turbulence, moderate icing
, instrument conditions with precipitation and mist, and mountain obscuration due to clouds, precipitation and mist along the route of flight.
levels should have the pilot considering a way out, while severe icing requires immediate and decisive action, even in protected aircraft.
