IR · ORO.FTL.110 — Regulation (EU) No 965/2012 · Regulation (EU) No 83/2014 · Air OPS Easy Access Rules · EAR revision 27 Mar 2026 AMC Acceptable means of compliance ## AMC1 ORO.FTL.110 Operator responsibilities SCHEDULING (a) Scheduling has an important impact on a [crew member](https://avioverse.aero/glossary/easa/crew-member)’s ability to sleep and to maintain a proper level of alertness. When developing a workable roster, the operator should strike a fair balance between the commercial needs and the capacity of individual crew members to work effectively. Rosters should be developed in such a way that they distribute the amount of work evenly among those that are involved. (b) Schedules should allow for flights to be completed within the maximum permitted flight [duty period](https://avioverse.aero/glossary/easa/duty-period) and flight rosters should take into account the time needed for pre-flight duties, taxiing, the flight- and turnaround times. Other factors to be considered when planning [duty](https://avioverse.aero/glossary/easa/duty) periods should include: (1) the allocation of work patterns which avoid undesirable practices such as alternating day/[night](https://avioverse.aero/glossary/easa/night) duties, alternating eastward-westward or westward-eastward time zone transitions, [positioning](https://avioverse.aero/glossary/easa/positioning) of crew members so that a serious disruption of established sleep/work patterns occurs; (2) scheduling sufficient rest periods especially after long flights crossing many time zones; and (3) preparation of duty rosters sufficiently in advance with planning of recurrent extended recovery rest periods and notification of the crew members well in advance to plan adequate pre-duty rest.

AMC · AMC1 ORO.FTL.110(j) — Regulation (EU) No 965/2012 · ED Decision 2014/017/R · Air OPS Easy Access Rules · EAR revision 27 Mar 2026 GM Guidance material ## GM1 ORO.FTL.110(j) Operator responsibilities OPERATIONAL ROBUSTNESS OF ROSTERS Performance indicators for operational robustness of rosters should support the operator in the assessment of the stability of its rostering system. Performance indicators for operational robustness of rosters should at least measure how often a rostered crew pairing for a [duty period](https://avioverse.aero/glossary/easa/duty-period) is achieved within the planned duration of that duty period. Crew pairing means rostered [positioning](https://avioverse.aero/glossary/easa/positioning) and flights for crew members in one duty period.
