Which SD risk factor can be readily and continually assessed?

• A. Meteorological conditions
• B. Lack of visual cues
• C. Decreasing flight visibility
• D. Task saturation

Answer: (D)

Task saturation refers to the amount of cognitive load or workload you’re under in the cockpit. In spatial disorientation, a high workload directly increases the chance of losing or misinterpreting attitude cues because your attention is stretched across many tasks. You can read this risk in real time by noticing how many tasks you’re handling, how quickly they must be done, and whether performance is slipping. When workload is high, your scan can become tunnel-visioned toward tasks rather than instruments, making you more prone to misreading orientation cues.

This is why it’s the best choice: it’s something you can readily and continually assess during flight—your own workload and its impact on performance—so you can take immediate steps to manage it, like simplifying tasks, using autopilot, or focusing your instrument cross-check.

The other factors are environmental or perceptual cues that aren’t as directly measurable in real time from the pilot’s internal state. Meteorological conditions and decreasing visibility are external conditions that can change and require outside information to assess, while a lack of visual cues describes the absence of external references rather than an ongoing internal workload assessment.
