Question 1

A pilot is flying toward a line of thunderstorms. During the mature stage of a thunderstorm cell, which of the following weather phenomena is most likely to be encountered?

Accepted Answer

Strong updrafts, downdrafts, and the onset of precipitation.

Answer

The mature stage of a thunderstorm is characterized by the presence of both strong updrafts and downdrafts, and it is the period when precipitation begins to fall from the cloud base. This stage is considered the most dangerous phase of a thunderstorm due to the combination of these hazardous conditions.

Question 2

A pilot is on approach to an airport and encounters a sudden, powerful downdraft that results in a rapid loss of airspeed and altitude. This phenomenon, typically less than 2.5 miles in diameter and lasting only a few minutes, is known as a:

Accepted Answer

Microburst

Answer

A microburst is a localized, intense downdraft that spreads out upon reaching the surface, creating strong and dangerous wind shear. It is small in scale (less than 2.5 miles or 4 km in diameter) and typically has a short duration of 5-15 minutes, posing a significant hazard during takeoff and landing.

Question 3

Under which conditions is advection fog most likely to form?

Accepted Answer

A warm, moist air mass moving over a colder surface.

Answer

Advection fog forms when moist air moves horizontally (advects) over a cooler surface, causing the air to cool to its dew point and form fog. This process requires wind to transport the air mass and can be very persistent and widespread.

Question 4

A pilot planning a flight over a mountain range notes a strong wind blowing perpendicular to the range and a stable air mass. Which of the following hazards should the pilot be most concerned about on the leeward side of the mountains?

Accepted Answer

Severe turbulence and strong vertical currents associated with mountain waves.

Answer

When strong winds flow perpendicular to a mountain range in a stable atmosphere, mountain waves can form on the downwind (leeward) side. These waves can create powerful updrafts and downdrafts (exceeding 2,000 ft/min), as well as severe to extreme turbulence in associated rotor clouds, posing a significant danger to aircraft.

Question 5

During a preflight check of weather, a pilot notes the following in a Terminal Aerodrome Forecast (TAF): TEMPO 1416 1/2SM +TSRA. What does this indicate?

Accepted Answer

Temporarily, between 1400Z and 1600Z, visibility will be one-half statute mile with thunderstorms and heavy rain.

Answer

In a TAF, 'TEMPO' indicates temporary fluctuations in weather conditions expected to last for less than an hour in each instance. '1416' specifies the time period (from 1400Z to 1600Z). '1/2SM' is the visibility in statute miles. '+TSRA' decodes as thunderstorms with heavy (+) rain (RA). Therefore, the forecast indicates temporary periods of 1/2-mile visibility with thunderstorms and heavy rain between 1400Z and 1600Z.
