Question: 1 / 400

How far does a microburst typically extend horizontally?

Less than 1 mile

2 nautical miles or less

A microburst typically extends horizontally for 2 nautical miles or less. This phenomenon is characterized by a powerful column of sinking air that can result in severe weather conditions, particularly during thunderstorms. When this air descends rapidly, it spreads out upon reaching the ground, creating strong downdrafts that can lead to sudden wind changes and turbulence.

The limited horizontal extent of a microburst is significant because it can catch pilots off guard, particularly while landing or taking off in the vicinity of thunderstorms. Understanding the scope of a microburst helps pilots recognize the potential for sudden changes in wind direction and intensity, which is crucial for flight safety.

The other choices do not accurately reflect the typical extent of a microburst's horizontal reach, with options suggesting ranges that are too extensive for this particular atmospheric phenomenon.
