ORO.FTL.235 Rest periods
(a) Minimum rest period at home base.
(1) The minimum rest period provided before undertaking an FDP starting at home base shall be at least as long as the preceding duty period, or 12 hours, whichever is greater.
(2) By way of derogation from point (1), the minimum rest provided under point (b) applies if the operator provides suitable accommodation to the crew member at home base.
(b) Minimum rest period away from home base. The minimum rest period provided before undertaking an FDP starting away from home base shall be at least as long as the preceding duty period, or 10 hours, whichever is greater. This period shall include an 8-hour sleep opportunity in addition to the time for travelling and physiological needs.
(c) Reduced rest By derogation from points (a) and (b), flight time specification schemes may reduce the minimum rest periods in accordance with the certification specifications applicable to the type of operation and taking into account the following elements:
(1) the minimum reduced rest period;
(2) the increase of the subsequent rest period; and
(3) the reduction of the FDP following the reduced rest.
(d) Recurrent extended recovery rest periods Flight time specification schemes shall specify recurrent extended recovery rest periods to compensate for cumulative fatigue. The minimum recurrent extended recovery rest period shall be 36 hours, including 2 local nights, and in any case the time between the end of one recurrent extended recovery rest period and the start of the next extended recovery rest period shall not be more than 168 hours. The recurrent extended recovery rest period shall be increased to 2 local days twice every month.
(e) Flight time specification schemes shall specify additional rest periods in accordance with the applicable certification specifications to compensate for:
(1) the effects of time zone differences and extensions of the FDP;
(2) additional cumulative fatigue due to disruptive schedules; and
(3) a change of home base.
