you are just tired!! Anyone else heard this from their enlightened management/safety department?
I think ICAO changed the definition a couple of years ago so that now if you're tired, you're fatigued. I know that Qantas a bunch of years ago had a distinction between being tired (not enough sleep last night) and fatigued (cumulative build up of disrupted rest or something like that) but to my pleasant surprise that changed a few years back.
This is the definition Qantas uses now:
A physiological state of reduced mental or physical performance capability resulting from sleep loss or extended wakefulness and/or physical activity that can impair a crew member’s alertness and ability to safely operate an aircraft or perform safety related duties.
So maybe someone should check the ICAO info and confirm if my recollection is correct. If so you may be able to educate your respective managers. Maybe the ISARPS mention it also?
This is the link Qantas provides to the CASA info.
