GVC Emergency and Contingency Procedures 2

Question 1

What is a 'Return to Home' (RTH) function and what should the pilot verify before each flight?

Accepted Answer

RTH automatically flies the UAS back to a preset point — the pilot must verify the home point is correctly set and the return altitude is safe

Answer

Return to Home (RTH) is an automated function that commands the UAS to fly back to a preset GPS coordinate (usually the take-off point). Before each flight, the pilot must verify the home point has been acquired correctly, and that the return altitude is set high enough to clear all obstacles along the return path. An incorrectly set home point or altitude can result in a collision or the drone returning to the wrong location.

Question 2

In the event of a GNSS (GPS) failure during flight, what is the most appropriate immediate action?

Accepted Answer

Switch to manual attitude mode, maintain visual contact, and land as soon as safely practicable

Answer

GNSS failure means the UAS loses its position reference and cannot hold a stable hover or navigate autonomously. The pilot should switch to a manual control mode (such as attitude/ATTI mode), maintain VLOS, and conduct a controlled landing as soon as safely practicable. Activating RTH is not viable without GNSS, and increasing altitude will not reliably restore the signal.

Question 3

What is a 'Controlled Impact' and when might it be the appropriate emergency response?

Accepted Answer

Deliberately flying the UAS into a non-populated area to prevent a worse outcome, such as crashing into a crowd

Answer

A controlled impact is a last-resort emergency procedure where the pilot deliberately directs the UAS to crash in the least harmful location available (such as an open field or body of water) to prevent a worse outcome, such as an uncontrolled descent into a gathering of people. It sacrifices the UAS to protect human safety.

Question 4

What information should a remote pilot record and report after a UAS incident?

Accepted Answer

Flight telemetry, location, time, weather, persons involved, damage assessment, witness details, and actions taken

Answer

After an incident, the pilot should record comprehensive details: time and location, flight telemetry/logs, weather conditions, description of the event, actions taken, details of any persons involved or injured, property damage assessment, witness contact information, and the UAS status. This information is required for the mandatory occurrence report to the CAA and for the operator's own records.

Question 5

How should a remote pilot respond if an uninvolved person enters the operational area during flight?

Accepted Answer

Assess the risk, manoeuvre the UAS away from the person, pause or abort the operation if necessary, and have a crew member warn them

Answer

The pilot should dynamically assess the risk, manoeuvre the UAS away from the uninvolved person to maintain safe separation, and if necessary pause or abort the operation. A crew member or observer should be tasked with approaching the person to warn them of the drone operation. The response should be proportionate to the risk level.
