Sample A2 CofC Drone Practice Questions

Try these questions from our free A2 CofC Drone practice tests. The correct answer and an explanation follow each question.

1. A remote pilot briefly loses direct Visual Line of Sight (VLOS) with their UAS as it passes behind a large building. According to standard UK emergency procedures, what is the most appropriate immediate action to safely regain VLOS?

   • A. A. Stop all horizontal movement and increase the UAS's altitude vertically until it is visible above the obstruction.
   • B. B. Immediately activate the Return to Home (RTH) function and wait for the UAS to return.
   • C. C. Continue flying the intended path using the map on the controller, assuming it will reappear shortly.
   • D. D. Rely on a remote observer, if present, to guide the aircraft back into view.

Answer: A. A. Stop all horizontal movement and increase the UAS's altitude vertically until it is visible above the obstruction.

The correct and safest procedure when VLOS is temporarily lost behind an obstacle is to stop any forward, backward, or sideways movement and command the UAS to ascend vertically. This allows the pilot to quickly re-establish visual contact over the top of the obstruction without flying blind into potential unseen hazards.

Answer: B. Immediately descend and move the drone away from the approaching aircraft's path

Drones must always give way to manned aircraft. The pilot should immediately reduce altitude and move the drone clear of the manned aircraft's flight path. Under UK regulations, drones must never be flown in a way that creates a collision hazard with manned aircraft.

Answer: C. Global Navigation Satellite System (GNSS)

The Return to Home (RTH) function works by recording the Global Navigation Satellite System (GNSS), most commonly GPS, coordinates at the point of take-off. When RTH is activated, the UAS uses its onboard GNSS receiver to navigate back to these stored coordinates. The IMU and barometer assist with stability and altitude, but the primary positioning data comes from GNSS.

Answer: B. Risk of thermal runaway leading to fire or explosion

A swollen or damaged LiPo (Lithium Polymer) battery is at risk of thermal runaway, which can cause the battery to catch fire, emit toxic fumes, or explode. A damaged LiPo should never be used and must be disposed of safely at a battery recycling point.
