Which data is used to change the flight path of a UAS to avoid obstacles and other aircraft?

• A. Active sensor data
• B. GPS location
• C. Altitude readings
• D. Battery level

Answer: (A)

Obstacle avoidance depends on sensing the environment in real time. Active sensor data powers that ability by emitting signals (like lidar, radar, or cameras with active sensing) and analyzing the reflections to detect obstacles or other aircraft. This current, real-world information about what’s around the drone is what the flight control system uses to decide to change course and avoid a collision. GPS location helps the drone know where it is and plan a route, but it doesn’t indicate nearby obstacles. Altitude readings tell how high the drone is, not what’s in its path. Battery level indicates remaining power, not obstacle geometry. So the data that directly drives path changes to prevent collisions is the active sensor data, which provides the immediate situational awareness needed for safe avoidance maneuvers.
