Fatigue Management

. a tendency to rely on others to make decisions or to shoulder group
tasks is induced;
c. failure to make comprehensive instrument scans;
d. a tendency to abbreviate or skip routine checks;
e. increasing frequency of errors of omission (failing to detect and/or
correct undesirable system performance or behaviour),
f. larger deviations allowed to occur before corrections are made, and
corrections tend to overcompensate;
g. more passive flight control strategies;
h. lower performance standards being accepted without realisation;
i. peripheral activities overlooked; and
j. micro-sleeps.
During Operation Desert Storm, the United States Air
Force observed that cumulative fatigue in C-5 air
transport flight crews resulted in the fumbling of radio
frequency changes, slowed reaction times, impaired
judgement, diminished checklist discipline, decreased
aircrew coordination and increased irritability.
