GVC Flight Planning and Navigation 2

Question 1

What does VLOS mean and what is its practical implication for UAS flight planning?

Accepted Answer

Visual Line of Sight — the remote pilot must maintain unaided visual contact with the UAS at all times

Answer

Very Low Operating Speed — the drone must fly below 20 mph

Answer

Vertical Launch and Observe System — the drone must take off vertically

Answer

Variable Level of Service — the drone adjusts autonomy based on signal strength

Question 2

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

Accepted Answer

Minimising flight time over uninvolved persons and congested areas

Answer

Achieving the most dramatic camera angles

Answer

Maximising the ground area covered per battery

Answer

Following the most direct straight-line path

Question 3

What is the purpose of establishing a 'flight geography' and 'contingency volume' in UAS flight planning?

Accepted Answer

To define the intended flight area and the additional airspace buffer for handling abnormal situations

Answer

To define the marketing area for the operator's services

Answer

To calculate the operator's insurance premium

Answer

To determine the number of observers required

Question 4

How does the remote pilot's position relative to the sun affect VLOS operations?

Accepted Answer

Looking toward the sun can cause glare, making it difficult to maintain visual contact with the UAS

Answer

It has no effect on modern drone operations

Answer

The sun improves visibility in all cases

Answer

The sun only affects operations above 200 metres

Question 5

What is an 'Emergency Response Plan' (ERP) and when must it be prepared?

Accepted Answer

A documented plan detailing actions to take in emergency scenarios — required before every Specific category operation

Answer

A plan for responding to equipment failure — only required for flights over 100 metres

Answer

A financial plan for replacing damaged equipment

Answer

A plan submitted to the emergency services after an incident

Question 6

Why is it important to check for electromagnetic interference (EMI) sources during a site survey?

Accepted Answer

EMI sources such as power lines, transmitters, and substations can interfere with the UAS control link and GNSS signals

Answer

EMI can charge the drone's battery faster

Answer

EMI only affects drones painted with metallic paint

Answer

EMI improves the drone's camera quality
