What should a remote PIC be cautious of when operating around buildings?

When operating around buildings, a remote pilot in command (PIC) should be particularly cautious of the creation of wind gusts that change rapidly in direction and speed. This phenomenon occurs primarily due to the interaction of wind with the structure of the buildings. When wind flows around a building, it can become turbulent, creating swirling eddies and downdrafts that can lead to sudden changes in wind speed and direction.

These changing conditions can significantly affect the stability and control of a drone. A drone that is navigating in turbulent air may experience abrupt shifts in altitude, making it more difficult for the pilot to maintain a steady flight path. This is critical to understand because operational safety and the ability to perform precise maneuvers are vital to drone operations, especially in urban environments where buildings can introduce complex wind patterns.

In contrast, decreased visibility and light loss, stable wind patterns, and higher chances of electromagnetic interference, while potentially important considerations, do not capture the immediate and dynamic risks associated with wind patterns caused by nearby structures. Understanding the behavior of wind in urban settings is essential for ensuring safe and efficient drone operations.
