Unit 2: TURBULENCE

What is turbulence?

• Irregular motion of the air resulting in throwing an airplane out of control or to cause structural damage

• Regular motion of the air resulting in throwing an airplane out of control or to cause structural damage

• Unplanned drop in the pressure of an aircraft

• Planned drop in the pressure of an aircraft

Which one of the below is not an example Severity of Turbulence?

• Light

• Moderate

• Extreme

• Extra Severe

When the turbulence is hardly noticeable to passengers, what is the Turbulence Intensity?

• Light

• Moderate

• Severe

• Extra Severe

The least severe, with slight, erratic changes in attitude and/or altitude is best known as

• Light Turbulence

• Moderate Turbulence

• Severe Turbulence

• Extreme Turbulence

Variations in speed as well as altitude and attitude may occur but the aircraft remains in control all the time.

• Light Turbulence

• Moderate Turbulence

• Severe Turbulence

• Extreme Turbulence

Loose objects may move around the cabin and damage to aircraft structures may occur.

• Light Turbulence

• Moderate Turbulence

• Severe Turbulence

• Extreme Turbulence

Capable of causing structural damage and resulting directly in prolonged, possibly terminal, loss of control of the aircraft is best known as

• Light Turbulence

• Extreme Turbulence

• Severe Turbulence

• Moderate Turbulence

Clear Air Turbulence (CAT) is best known as

• Sudden severe turbulence occurring in cloudless regions that causes violent buffeting of aircraft.

• A region of low pressure causing an aircraft to lose height suddenly

• Very strong air corridors found at high altitudes

• Turbulence depends the size and shape of the obstructions

Mechanical Turbulence is best known as

• Sudden severe turbulence occurring in cloudless regions that causes violent buffeting of aircraft.

• Turbulence depends the size and shape of the obstructions

• Strong air corridors found at high altitudes. They form between the boundaries of warm and cold air.

• A region of low pressure causing an aircraft to lose height suddenly

A region of low pressure causing an aircraft to lose height suddenly is known as

• Air Pocket

• Jet Streams

• Mechanical Turbulence

• Clear Air Turbulence
