You don’t know how poorly you will perform….or do you?
If people are not that great at judging their own fatigue levels without a validated questionnaire, should we even consider getting them to judge how well they will perform at their current level of fatigue?

Cranky Shift-Workers: It’s not their fault!
A functional magnetic resonance imaging (fMRI) study showed that the amygdala’s reaction to negative emotional stimuli is greater in magnitude/intensity and volume in people who miss a night of sleep when compared to a control group. This study also showed that the connections between the amygdala and the MPFC were weaker in the sleep deprived group. This means that the amygdala’s reactions can’t be inhibited as well by the MPFC in people who lack sleep.

3 Rules for Napping as a Fatigue Countermeasure
If you are developing a controlled rest procedure, here are 3 rules to keep in mind.
Rule 1: Some sleep is better than no sleep.
Rule 2: The second rule is that more sleep is always better.
Rule 3: The last rule is that sleep inertia needs to dissipate before a napper can be re-engaged in safety critical activities.
W5 Jet-Lagged
Fatigue countermeasures are strategies that can be used to fight fatigue that takes hold during duty. They should not be used routinely to keep pilots, mariners or train engineers and conductors alert and safe. Instead, fatigue prevention strategies should be the mainstay for alertness and safety. If people are routinely napping on the job, then they are too fatigued probably because the fatigue prevention strategies are failing.

Earlier this month the NTSB released an update into their investigation of the Airbus A320 that squeezed through a potential disaster by less than 59 feet. I finally found time to read through the update and it looks like the NTSB is sticking to their protocol of only releasing validated factual information. This is a good thing; it is still way too early to thoroughly identify all the causal factors. Plus, dropping hints at what they are considering would result in too much conjecture and a knee jerk reaction to stick together a patchwork of solutions.

There is a hint in the report about how communication between the Medical Examiner and the pilot may have played a role in allowing a person with an untreated sleep disorder to continue to operate. The report said that the pilot with obstructive sleep apnea (OSA) did not report any daytime sleepiness to the doctor. There are two reasons why the sleepiness may not have been reported.
