What type icing, if any, will an aircraft encounter if icing conditions are favorable and
flying above 12,000 feet in a stratiform cloud?

Mixed

With a frontal system, the greatest icing occurs when updrafts exist. The only exception to
this rule is when icing is associated with

freezing precipitation

a warm frontal occlusion

supersaturated clouds.

a cold frontal occlusion

inflow in a digging jet.

How can an aircrew avoid the effects of wake turbulence?

Land beyond the touchdown point of a leading aircraft, lift off behind the liftoff point of a leading aircraft, and fly above leading aircraft

Land beyond the touchdown point of a leading aircraft, lift off ahead of the liftoff point of a leading aircraft, and fly above leading aircraft.

Land ahead of the touchdown point of a leading aircraft, lift off behind the liftoff point of a leading aircraft, and fly below leading aircraft

Land ahead of the touchdown point of a leading aircraft, lift off ahead of the liftoff point of a leading aircraft, and fly below leading aircraft

Anti-icing equipment

Deicing equipment

Ice removal blowers

Ionization equipment

What icing intensity corresponds to freezing drizzle?

Moderate.

Light

Extreme

Severe

14.

1 point

When forecasting weather you would expect low-level wind shear when

sustained surface wind is 10 knots or greater

sustained surface wind is less than 10 knots and the absolute value of the vector difference between the gradient wind and the surface wind is 30 knots or greater and an inversion or isothermal layer is present below 2,000 feet.

thunderstorms are observed or forecast within 20 nautical miles of the aerodrome.

sustained surface wind is 10 knots or greater and the difference between the gradient wind speed and twice the surface wind speed is 20 knots or greater.
