What is the recommended action if a UAS remote controller displays a 'signal lost' warning during flight?
Answer: Allow the drone to execute its programmed Return-to-Home (RTH) failsafe
Most UAS are programmed with a Return-to-Home failsafe that automatically activates when the RC link is lost, safely returning the drone to the launch point.
Which component of a UAS flight controller is responsible for detecting rotational movement and providing attitude stabilization?
Answer: Gyroscope (IMU)
The gyroscope within the Inertial Measurement Unit (IMU) detects angular velocity and feeds data to the flight controller for real-time attitude correction.
A pilot notices propeller vibration during a hover test. What is the most likely cause?
Answer: Propeller imbalance or damage
Propeller imbalance or physical damage creates asymmetric aerodynamic forces that manifest as vibration, which can damage motors and reduce control authority.
What does 'Return-to-Home altitude' refer to in UAS flight planning?
Answer: The altitude the drone climbs to before flying back to the home point
RTH altitude is a pre-set height the drone climbs to before navigating home, ensuring it clears obstacles in the flight path.
In UAS telemetry, what does RSSI stand for?
Answer: Received Signal Strength Indicator
RSSI (Received Signal Strength Indicator) measures the power level of the received radio signal, helping the pilot assess link quality and communication range.
What is the function of a UAS geofencing system?
Answer: Creates virtual boundaries that prevent the aircraft from entering restricted areas
Geofencing uses GPS coordinates to define virtual boundaries, automatically preventing the drone from flying into restricted or hazardous zones.
When performing a hover test after maintenance, why should the pilot keep the drone low and near their position?
Answer: To quickly land or cut power if an anomaly is detected before risking a full mission
A low, close hover test allows the pilot to observe the drone directly and react immediately to any anomalies such as vibration, drift, or noise before committing to a full flight.
