Thunderstorms reach their greatest intensity during the

• mature stage.

• downdraft stage.

• cumulus stage.

Thunderstorms that generally produce the most intense hazard to aircraft are

• squall line thunderstorms.

• steady-state thunderstorms.

• warm front thunderstorms.

A nonfrontal, narrow band of active thunderstorms that often develop ahead of a cold front is known as a

• prefrontal system.

• squall line.

• dry line.

If thunderstorm activity is in the vicinity of an airport at which you plan to land, which hazardous atmospheric phenomenon might be expected on the landing approach?

• Precipitation static.

• Wind-shear turbulence.

• Steady rain.

Which weather phenomenon is always associated with a thunderstorm?

• Lightning.

• Heavy rain.

• Hail.

What cloud types would indicate convective turbulence?

• Cirrus clouds.

• Nimbostratus clouds.

• Towering cumulus clouds.

What clouds have the greatest turbulence?

• Towering cumulus.

• Cumulonimbus.

• Nimbostratus.

Upon encountering severe turbulence, which flight condition should the pilot attempt to maintain?

• Constant altitude and airspeed.

• Constant angle of attack.

• Level flight attitude.

Wingtip vortices are created only when an aircraft is

• operating at high airspeeds.

• heavily loaded.

• developing lift.

The greatest vortex strength occurs when the generating aircraft is

• light, dirty, and fast.

• heavy, dirty, and fast.

• heavy, clean, and slow.
