M6 - 1A

Which weather element dictates the runway to be used for takeoff and landing?

• Temperature

• Pressure

• Wind

• Humidity

How does warm air affect an aircraft's performance?

• It increases lift and improves engine performance.

• It decreases lift and negatively impacts performance.

• It has no effect on the aircraft's lift.

• It only affects the aircraft's landing capabilities.

A change in what weather element can greatly alter an airplane's altimeter readings?

• Humidity

• Atmospheric pressure

• Wind speed

• Temperature

Which of these cloud types are known for indicating thunderstorms and heavy rain?

• Cirrus (Ci)

• Cumulus (Cu)

• Stratus (St)

• Cumulonimbus (Cb)

What is a METAR?

• A 24 to 30-hour weather forecast for the area around an airport.

• A warning for severe weather like volcanic ash or severe turbulence.

• A real-time, hourly weather report for airports.

• A chart showing pressure systems and fronts.

Which forecast tool helps pilots anticipate weather conditions for a 24 to 30-hour period for flight planning?

• TAF

• SIGMET

• METAR

• AIRMET

What is the primary purpose of a SIGMET?

• To provide information about moderate weather conditions.

• To warn of severe weather that may affect aircraft safety.

• To show real-time precipitation intensity.

• To report hourly weather observations.

Turbulence that occurs in cloudless regions, usually above 15,000 ft and near jet streams, is known as:

• Mechanical Turbulence

• Thermal Turbulence

• Wake Turbulence

• Clear-Air Turbulence

What is mechanical turbulence?

• Turbulence caused by the uneven heating of the ground.

• A disturbance that forms behind an aircraft as it passes through the air.

• Irregular airflow caused by wind passing over obstacles like buildings.

• Turbulence that occurs where warm and cold air masses meet.

What is the hazard of aircraft icing?

• It improves the aerodynamic shape of the wing.

• It increases thrust and lift.

• It disrupts airflow, reduces lift, and adds weight.

• It enhances the pilot's visibility.
