QUESTIONAccording to the Remote Pilot Study Guide, skill fatigue has which two main effects on performance?

  1. ATiming disruption and disruption of the perceptual field
  2. BLoss of consciousness and muscle spasms in the hands and feet
  3. CIncreased heart rate and increased perspiration
Show the answer and explanation

Correct answer: A. Timing disruption and disruption of the perceptual field

  • A — correct The study guide identifies skill fatigue, a special type of acute fatigue, as having two main effects: timing disruption and disruption of the perceptual field.
  • B — incorrect These are symptoms the study guide lists for hyperventilation, not the effects of skill fatigue.
  • C — incorrect These are part of the body's reaction to stress described in the study guide, not the two effects of skill fatigue.

BACKGROUND

Fatigue is frequently associated with pilot error and degrades attention, concentration, coordination, and the ability to communicate. The Remote Pilot Study Guide describes skill fatigue as a special type of acute fatigue with two main effects. Timing disruption means the pilot appears to perform a task as usual, but the timing of each component is slightly off, making the operation less smooth. Disruption of the perceptual field means the pilot concentrates on movements or objects in the center of vision and neglects the periphery, with loss of accuracy and smoothness in control movements. Causes of acute fatigue include mild hypoxia, physical stress, and psychological stress.

STUDY TIP

Link skill fatigue to its two named effects and be able to describe what each one looks like in practice.

KEY POINTS

  • Skill fatigue is a special type of acute fatigue.
  • Timing disruption: each task component is slightly off, so the operation is less smooth.
  • Perceptual field disruption: attention narrows to the center of vision and neglects the periphery.
