Mixed Deck — All GVC Topics Flashcards

How does acute stress most commonly affect a remote pilot's cognitive performance?

Answer: It narrows attentional focus and can lead to tunnel vision and poorer decisions

Acute stress narrows attentional focus, impairs cognitive flexibility, and can lead to hasty or poor decisions, a phenomenon known as perceptual narrowing or tunnel vision.

What minimum age must a pilot be to hold a GVC in the UK?

Answer: 18 years old

The minimum age for GVC holders is 18 years old. This higher threshold than the open category (16) reflects the increased responsibility and complexity of specific category operations, which often involve commercial clients, public areas, or more complex airspace.

What is 'wind shear' and why is it hazardous to UAS operations?

Answer: A sudden change in wind speed or direction over a short distance, which can cause loss of control

Wind shear is a sudden change in wind speed, direction, or both over a short distance (either vertically or horizontally). For UAS, wind shear can cause sudden uncommanded changes in altitude or position, potentially leading to loss of control, collision with obstacles, or departure from the operational volume. It commonly occurs near buildings, terrain features, and during thunderstorm activity.

In SORA, what does 'strategic mitigation' for air risk involve?

Answer: Measures applied at the planning stage to reduce the probability of encountering manned aircraft

Strategic mitigations for air risk are measures implemented at the planning stage, such as restricting operations to airspace with low manned aircraft traffic, coordinating with air traffic services, or applying temporal restrictions. These reduce the probability of a mid-air encounter before the flight even begins.

Why should LiPo batteries never be charged on or near flammable materials?

Answer: LiPo batteries can catch fire or explode if they fail during charging — a LiPo-safe bag or fireproof charging container should always be used

LiPo batteries can experience thermal runaway — a self-reinforcing overheating reaction that can result in fire or explosion. Charging on a flammable surface dramatically increases the risk of fire damage. LiPo-safe bags or fireproof charging cases contain the hazard if a fire occurs.

In SORA, what is the purpose of determining the 'intrinsic Ground Risk Class' (iGRC)?

Answer: To establish the baseline ground risk before mitigations are applied

The intrinsic Ground Risk Class (iGRC) establishes the initial, unmitigated risk level of the operation to people on the ground. It is determined by the UAS characteristics (size, kinetic energy) and the operational environment (population density). Mitigations can then be applied to reduce this to a final GRC.

Under UK regulations, what is the minimum age requirement to register as a drone operator with the CAA?

Answer: 18 years old

To register as a drone operator with the UK CAA, a person must be at least 18 years old. However, remote pilots (the person physically flying) can be younger, provided they are supervised by a registered operator who takes responsibility.

What is 'plan continuation bias' (sometimes called get-there-itis) in UAS operations?

Answer: The tendency to continue with an original plan even when circumstances have changed unfavourably

Plan continuation bias is the tendency to press on with an original plan despite new information indicating it should be abandoned, and is a significant cause of accidents.

What is an 'Operational Safety Objective' (OSO) in the SORA framework?

Answer: A specific safety requirement that must be met based on the SAIL level

Operational Safety Objectives are specific safety requirements assigned based on the SAIL level. Each OSO addresses a particular risk area (e.g., pilot competency, UAS design, maintenance) and must be met to the required level of robustness (low, medium, or high) depending on the SAIL.

What is the significance of a drone manufacturer's specified 'maximum wind speed rating' for a commercial operator?

Answer: Operations must not take place when wind speeds exceed this rating — it defines the aircraft's safe operating envelope

The manufacturer's maximum wind speed rating defines the operational envelope for which the aircraft was designed and tested. Exceeding this limit risks loss of control because the drone's motors cannot maintain stable flight against stronger winds. Commercial operators must check forecast and actual wind conditions before and during flight.

In a drone operational risk assessment, what is meant by 'Ground Risk Class' (GRC)?

Answer: A measure of the expected severity of harm to people on the ground if the drone crashes

Ground Risk Class (GRC) is used in the SORA methodology to quantify the risk to people on the ground in the event of an uncontrolled landing or crash. It considers factors such as drone size, population density below the flight path, and whether the area is controlled (e.g., a cordoned-off site).

What is the role of a UK National Qualified Entity (NQE) in the context of GVC training?

Answer: NQEs are CAA-approved organisations that deliver GVC training, conduct assessments, and issue the qualification

NQEs are private training organisations approved by the CAA to deliver drone qualifications including the GVC. They provide the practical and theoretical training, conduct the required assessments, and on successful completion issue the certificate. The CAA sets the standards that NQEs must meet.

What does BVLOS stand for in drone operations?

Answer: Beyond Visual Line of Sight

BVLOS — Beyond Visual Line of Sight — refers to drone operations where the pilot cannot maintain unaided direct visual contact with the drone. BVLOS operations are in the specific or certified category and require additional mitigations such as ground observers, detect-and-avoid systems, and CAA authorisation.

When planning a flight route for a commercial UAS operation, which of the following should be given the HIGHEST priority?

Answer: Minimising flight time over uninvolved persons and congested areas

Safety is the overriding priority in flight planning. Routes should be planned to minimise overflying uninvolved persons, congested areas, and sensitive sites. This reduces the ground risk and is a key element of the operator's duty of care and SORA compliance.

How long is a GVC valid before it must be renewed?

Answer: 5 years, after which a revalidation assessment is required

The GVC is valid for 5 years from the date of issue. Before expiry, holders must complete a revalidation assessment with an NQE to demonstrate continued competency. This ensures that GVC holders keep their knowledge and skills current.

What is the primary technical challenge in enabling safe BVLOS drone operations?

Answer: Detect and Avoid (DAA) — ensuring the drone can detect and avoid conflicting traffic without the pilot seeing the airspace

In VLOS operations, the pilot's eyes provide the detect-and-avoid function. In BVLOS, this function must be provided by technology (onboard sensors, radar, ADS-B receivers) or procedural means (ground observers, traffic management systems) to prevent mid-air collisions.

What is the primary purpose of Crew Resource Management (CRM) in UAS operations?

Answer: To optimise the use of all available resources to enhance safety and efficiency

CRM focuses on optimising the use of all available resources — people, equipment, and information — to enhance safety and operational effectiveness.

What does the GVC qualification enable a remote pilot to do under UK drone regulations?

Answer: Fly in the Specific category under PDRA01 and applicable standard scenarios

The GVC (General VLOS Certificate) is a competency certificate that enables remote pilots to fly under PDRA01 (and applicable standard scenarios) within the Specific category. It does not grant unrestricted airspace access or BVLOS privileges.

Why is it important to identify overhead power lines and pylons when planning a commercial drone flightpath?

Answer: Power lines are difficult to see and detect electronically; striking them can cause loss of the aircraft, fire, and power outages affecting large areas

Power lines and pylons are among the most hazardous obstacles for low-level drone operations. They are often difficult to spot visually and are not reliably detected by standard drone sensors. Striking a high-voltage line can destroy the drone, cause a fire, and cut power to homes and businesses — consequences far beyond loss of the aircraft.

What is the primary safety concern associated with operating a drone after taking certain medications?

Answer: Certain medications can impair cognitive function, judgement, and reaction time

Certain medications, including some that are legally prescribed, can impair alertness, cognitive function, and reaction time, directly affecting the remote pilot's ability to operate safely.
