FAA 107 Commercial Drone Pilot Practice Exam

Question: 1 / 400

What defines a convective current in aviation?

Steady wind patterns

Uneven heating that causes air circulation

A convective current in aviation is defined by uneven heating that causes air circulation. This process occurs when different surface areas of the Earth absorb heat at different rates. For example, land heats up faster than water, leading to warm air rising over the heated surface. This rising warm air creates a vertical movement, which is the basis for convective currents.

As warm air ascends, cooler air moves in to replace it, creating a cycle of air movement that can lead to turbulence. Convective currents are particularly significant in aviation because they can affect flight conditions, particularly during takeoff and landing, when aircraft are more susceptible to these changes in airflow. Understanding convective currents is crucial for pilots to anticipate turbulence and ensure safe flight operations.
