Sector ORO.FTL.105 (24), (see also ORO.FTL.205 (f)(6)): In an abnormal or emergency situation a take-off might not be executed meaning that a sector was not completed. Such situation is likely to increase flight crew workload and fatigue. How could this be mitigated?
In such cases, in order to mitigate the increased workload and fatigue, the commander has the possibility to exercise commander’s discretion and decide on reducing the maximum daily FDP or increasing the minimum rest period.
ORO.FTL.205 (f)(6) requires operators to implement a non-punitive process for the use of commander’s discretion.
Also, if as a result of such situation a flight crew member feels unfit dues to fatigue, he/she may discontinue his duties on the aircraft for the day.
Regulation (EU) No 376/2014 on the reporting, analysis and follow-up of occurrences in civil aviation, requires the ability for crew members to report fatigue.
