Final answer:
A microburst is a threat to aviation due to its powerful downdrafts and strong winds. Pilots need to be aware of their presence and take precautions to avoid them.
Step-by-step explanation:
A microburst is a threat to aviation due to its powerful downdrafts and strong winds. It is typically associated with thunderstorms and can cause sudden and severe changes in wind direction and speed.
Microbursts can be extremely dangerous for aircraft during takeoff and landing because they can quickly push the plane downward or sideways, potentially causing loss of control. Pilots need to be aware of the potential presence of microbursts and take precautions to avoid them, such as utilizing advanced weather radar systems to detect their presence.
