GVC Human Factors & Crew Resource Management 2 — Questions and Answers
Question 1: In the context of human factors, what does 'complacency' refer to in UAS operations?
- Overconfidence and reduced vigilance that develops during routine operations (Correct answer)
- Careful and methodical attention to detail during repetitive tasks
- A formal method of risk assessment used during pre-flight planning
- The tendency to be overly cautious and conservative during all flights
Correct answer: Overconfidence and reduced vigilance that develops during routine operations
Complacency is reduced vigilance or overconfidence that commonly develops during routine or repetitive operations, increasing the likelihood of missing critical information.
Question 2: The 'Swiss Cheese Model' is used to explain which safety concept in UAS operations?
- How multiple defensive layers can fail simultaneously to allow an accident to occur (Correct answer)
- The importance of following aircraft maintenance schedules rigorously
- The methodology for completing a risk matrix assessment
- How communication failures occur between remote pilots and ATC
Correct answer: How multiple defensive layers can fail simultaneously to allow an accident to occur
The Swiss Cheese Model illustrates how accidents occur when weaknesses (holes) in multiple defensive layers align, allowing a hazard to pass through all defences and cause harm.
Question 3: What is the correct approach when a remote pilot feels pressured by a client to fly despite having genuine safety concerns?
- Continue the flight but increase personal vigilance throughout
- Defer to the client's wishes as they accept contractual responsibility
- Assert the concern clearly and decline to fly if necessary, as the pilot is always responsible for safety (Correct answer)
- Complete the flight as quickly as possible to minimise overall exposure to risk
Correct answer: Assert the concern clearly and decline to fly if necessary, as the pilot is always responsible for safety
The remote pilot in command is always legally and operationally responsible for the safe conduct of the flight and must decline to fly if genuine safety concerns are not resolved.
Question 4: How does acute stress most commonly affect a remote pilot's cognitive performance?
- It improves focus and accelerates decision-making in emergency situations
- It narrows attentional focus and can lead to tunnel vision and poorer decisions (Correct answer)
- It has no measurable effect on the performance of experienced pilots
- It increases the pilot's ability to process multiple information streams simultaneously
Correct 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.
Question 5: What is 'channelised attention' and why is it particularly hazardous in UAS operations?
- Focusing exclusively on radio communications to the detriment of other tasks
- Focusing so intently on one task that other critical factors in the environment are neglected (Correct answer)
- A navigation technique that uses designated radio frequency channels
- The process of actively monitoring multiple flight parameters simultaneously
Correct answer: Focusing so intently on one task that other critical factors in the environment are neglected
Channelised attention (tunnel vision) means concentrating so intensely on a single element that the pilot loses awareness of other critical factors, which is especially dangerous in a complex drone operating environment.
Question 6: Which of the following represents a 'latent condition' as described by the Swiss Cheese Model?
- A bird strike that occurs unexpectedly during a flight
- Inadequate training procedures embedded within an organisation's culture (Correct answer)
- A sudden and unexpected motor failure during operations
- A pilot's error in misreading a weather forecast before flight
Correct answer: Inadequate training procedures embedded within an organisation's culture
Latent conditions are pre-existing organisational or systemic weaknesses, such as poor training, that lie dormant until triggered by an active failure, contributing to an accident.
Question 7: What is the primary safety concern associated with operating a drone after taking certain medications?
- Some medications may interfere with the drone's radio control signal
- Certain medications can impair cognitive function, judgement, and reaction time (Correct answer)
- Medications must be declared to the UK CAA before each operational flight
- There is no specific concern provided the medication is lawfully prescribed by a doctor
Correct 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.
