GVC BVLOS Fundamentals & Flightpath Planning

Question 1

What does BVLOS stand for in drone operations?

Accepted Answer

Beyond Visual Line of Sight

Answer

Basic Visual Launch and Operating System

Answer

Below Visual Level of Sky

Answer

Boundary Visual Limit of Operations

Question 2

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

Accepted Answer

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

Answer

Maintaining GPS signal over longer distances

Answer

Battery technology limiting range to under 10 km

Answer

Regulatory approval timelines being too long

Question 3

When planning a commercial drone flightpath, what is the significance of identifying 'emergency landing sites'?

Accepted Answer

Pre-planned emergency landing sites allow the pilot to quickly direct the drone to a safe location in the event of a technical failure or other emergency

Answer

Emergency landing sites are legally required to be marked on all flight plans submitted to the CAA

Answer

Emergency landing sites only matter for BVLOS operations

Answer

Identifying them satisfies insurance requirements but has no operational value

Question 4

What role does a Ground Observer (GO) play in a commercial VLOS drone operation with multiple crew?

Accepted Answer

The GO maintains visual contact with the drone and communicates traffic or hazard information to the remote pilot

Answer

The GO operates the drone controls while the pilot monitors the camera feed

Answer

The GO is responsible for managing public access to the exclusion zone only

Answer

The GO submits NOTAMs on behalf of the operation

Question 5

What is the purpose of a 'flight plan' in the context of a commercial GVC drone operation?

Accepted Answer

To document the intended route, altitude, timing, contingency procedures, and emergency actions before the flight takes place

Answer

To formally request ATC clearance via the NATS system

Answer

To log the flight after it has been completed for records purposes

Answer

To comply with CAA requirements that all commercial flights be pre-planned 48 hours in advance

Question 6

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

Accepted 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

Answer

Drones must fly above 500 m AGL when near power lines under UK law

Answer

Power lines generate magnetic interference that disrupts the drone's compass

Answer

Power line corridors are always within restricted airspace requiring CAA authorisation
