A2 CofC - Drone Certificate of Competency Technical Mitigations for Ground Risk Questions and Answers

Question 1

A remote pilot operating under an A2 CofC is using a C2-class drone near people.
Which technical feature is specifically designed to allow for a reduction in the required horizontal separation distance from uninvolved people from 30 metres to 5 metres?

Accepted Answer

A low-speed mode limited to a maximum of 3 m/s

Answer

A certified emergency parachute system

Answer

Detachable propeller guards

Answer

An advanced Return-to-Home (RTH) function

Question 2

Which of the following best describes the role of a manufacturer's built-in geo-awareness system as a technical mitigation for ground risk in the UK?

Accepted Answer

It provides advisory information, but the remote pilot must always verify airspace restrictions using official sources like the UK AIP.

Answer

It is a legal requirement mandated by the CAA for all operations.

Answer

It automatically prevents the drone from entering any restricted airspace, removing the need for pilot checks.

Answer

It is only designed to warn of other manned aircraft and has no function for ground-based restrictions.

Question 3

A remote pilot is planning an operation in a congested area and wants to minimise the ground risk to uninvolved persons. From a purely technical mitigation perspective, what is the primary safety benefit of using propeller guards?

Accepted Answer

They provide a physical barrier to reduce the severity of injury from direct contact with rotating propellers.

Answer

They significantly reduce the overall noise profile of the drone.

Answer

They prevent the propellers from spinning in the event of a motor failure.

Answer

They improve the aerodynamic efficiency, allowing for longer flight times.

Question 4

While not mandatory for most A2 Open Category operations, an aftermarket ballistic parachute recovery system is considered a significant technical mitigation because it is designed to:

Accepted Answer

reduce the drone's rate of descent and impact energy in the event of a critical in-flight failure.

Answer

increase the drone's flight time by providing lift.

Answer

allow the drone to be legally flown over crowds in the Open Category.

Answer

automatically navigate the drone back to the take-off point.

Question 5

You are operating a 1.8 kg 'legacy' drone (without a C-class marking) under your A2 CofC. You intend to fly in a park where members of the public are present. According to CAA regulations, what is the minimum horizontal separation distance you must maintain from uninvolved people?

Accepted Answer

50 metres, with no reductions permitted.

Answer

30 metres, reducing to 5 metres in low-speed mode.

Answer

150 metres at all times.

Answer

There is no minimum distance, but you must not intentionally overfly them.

Question 6

To operate in the A2 subcategory, a drone must have a UK C2 class marking (or equivalent). Which of the following is NOT a technical requirement or characteristic for a C2-class drone?

Accepted Answer

It must have adjustable noise reduction settings for urban environments.

Answer

It must be equipped with a system for Remote ID.

Answer

It must have a maximum take-off mass of less than 4 kg.

Answer

It must be safely controllable, considering aspects like performance and stability.
