| SUMMARY: | A simulator study of student pilots flying instrument approaches. They varied workload and measured how pilots performed in both accuracy and task initiation, duration and completion time. Found that pilots that switched tasks quickly and did not dwell on a particular tasks performed the best. |
SIGNIFICANT CONCEPTS/EXCERPTS:
Two types of biases considered: as-if (all tasks have equal task priority/importance), overconfidence (overconfidence in one's own perceived level of performance on tasks).
As workload increases, lower priority tasks are degraded or shed. Also, they often failed to reschedule dropped tasks.
Pilots that performed well scheduled tasks early. If they didn't start tasks early, later their workload was increased and they often dropped tasks that they could have done earlier.
Pg. 224 is a table of 30 tasks ranked in priority (by subjects and flight instructors).
Pilots almost always started tasks on time or late, never early. (can you perform a task early?)
No evidence for "As-if" bias (so pilots can differentiate between low/high priority tasks).
Under high workloads, pilots did not perform tasks faster. Perhaps tasks were already as fast as possible.
Pg. 236 - ".. the better performing pilots performed their tasks earlier and also tended to be somewhat more flexible in switching between tasks."
