CTO Fatigue Management & Human Factors 3

Question 1

According to Threat and Error Management (TEM) principles, which step should occur FIRST when a controller detects an undesired aircraft state?

Accepted Answer

Detect and identify the threat

Answer

TEM requires that threats be detected and recognized before any response or coordination action can be appropriately executed.

Question 2

Which type of error is MOST associated with high workload conditions in tower operations?

Accepted Answer

Slips

Answer

Slips—unintended actions on an otherwise correct plan—spike in frequency during high-workload periods when attention is divided.

Question 3

A strategic nap of 10–20 minutes before a night shift primarily benefits controllers by:

Accepted Answer

Reducing sleep inertia effects and boosting alertness during the shift

Answer

A short prophylactic nap improves alertness and reaction time without producing significant sleep inertia, making it effective before night work.

Question 4

Situation awareness (SA) in ATC is BEST described as:

Accepted Answer

Perception, comprehension, and projection of traffic elements over time

Answer

Endsley's three-level SA model defines it as perceiving elements, understanding their meaning, and projecting future status.

Question 5

Which factor most significantly degrades a controller's situation awareness during periods of low traffic?

Accepted Answer

Complacency and reduced vigilance

Answer

Low traffic lulls controllers into complacency, reducing active monitoring and making it easier to miss infrequent but critical events.
