FAQ n.47582

Yes, provided that the changes do not breach the limitations of the operator’s Individual Flight Time Specification Scheme (IFTSS).

All changes must be notified to the crew member before the pre-flight rest period commences so that the crew member is able to plan adequate rest as required by ORO.FTL.110 (a).

In support of this requirement the minimum period of time for notification of changes should be established by the operator and available in the Operations manual
