Drone Pilot Practice Exam

As altitude increases, the atmosphere becomes less dense. This means that there are fewer air molecules above a given point, resulting in lower air pressure at higher elevations. This phenomenon occurs because gravity pulls air molecules toward the Earth's surface; as you move further from the surface, the weight of the air above decreases, leading to a decrease in pressure. In the context of drone operation, this decrease in air pressure can significantly impact drone performance, including lift capabilities and battery efficiency. Pilots must understand this principle to ensure safe and effective operation of their drones at various altitudes.
