Explain the typical triggers and action of a Return-to-Home (RTH) procedure.

• A. Triggered by manual activation only; drone ascends vertically.
• B. Triggered by loss of control link, low battery, or manual activation; drone returns to takeoff point or designated location and lands safely.
• C. Initiates automatically at sunset.
• D. Always directs drone to nearest safe landing zone.

Answer: (B)

Return-to-Home is a safety feature that activates when the drone detects a problem with communication, power, or when the pilot triggers it manually. The typical triggers are losing the control link, the battery dropping to a level where returning safely is required, or the pilot pressing the RTH control. When this happens, the drone heads back to a known location—the takeoff point or a designated home point—and lands there safely. To make the return predictable and safe, it usually climbs to a preset RTH altitude to clear obstacles, uses its stored home position to navigate back, and then lands. This behavior prioritizes bringing the aircraft to a known, safe location rather than continuing flight when conditions are uncertain.
