Or, how to put a quart into a pint pot.
Cheers Bumaye – ICAO - ANSP ATC Duty Hours and FRMS SARPs effective 5/11/20 makes for an interesting read. Its dry as sticks, but you can see what they are trying to do. Fatigue is becoming one of those nebulous words which creep into the lexicon and takes on many meanings; far removed from the true definition.
Wiki – “Fatigue is a subjective feeling of tiredness which is distinct from weakness, and has a gradual onset. Unlike weakness, fatigue can be alleviated by periods of rest. Fatigue can have physical or mental causes”.
The ICAO objective is quite clear; well, as near as words, science and systems can get to making certain no one is ‘fatigued’ and, if they are then there is a safety net, and; a system which can monitor ‘trends’. All good solid ‘system’ stuff which makes sense.
2.1.3 Reactive.
The reactive process shall identify the contribution of fatigue hazards to reports and events associated with potential negative safety consequences in order to determine how the impact of fatigue could have been minimized. At a minimum, the process may be triggered by any of the following:
a) fatigue reports;
b) confidential reports;
c) audit reports; and
d) incidents.
Now I’m not knocking the ICAO effort at all; the whole thing is complex and, as ‘systems’ come on line, no doubt there will be further amendments made to reflect the data returned – this is a good thing and proper. However, the use of the word ‘subjective’ in the (click English) dictionary definition (IMO) defines the radical. I note that the word ‘tired’ is often lumped into the mix of science, speculation and hearsay. I wonder, could ‘tired’ not be disassociated, as it is a very different animal. Another word which needs to be considered is ennui. Being ‘Tired’ and suffering ’Ennui’ are not the same thing as ‘being fatigued’ – which bring human factors (and nature) into the equation, and good luck ‘quantifying’ that little puzzle.
The challenge to quantify and numerically define ‘fatigue’ is a big one as IMO, it comes down to the individual; what wearies one is a stroll in the park for another. But a system is needed and to do that data must be collected, collated, analyzed and turned into guidelines. Once that is managed it will be turned into a rule set – with sharp edges and clearly defined corners. Enter the dragons, human nature and lawyers.
Toot toot.
