ORO.FTL.205 Flight duty period (FDP)
(a) The operator shall:
(1) define reporting times appropriate to each individual operation taking into account ORO.FTL.110(c);
(2) establish procedures specifying how the commander shall, in case of special circumstances which could lead to severe fatigue, and after consultation with the crew members concerned, reduce the actual FDP and/or increase the rest period in order to eliminate any detrimental effect on flight safety.

(2) The maximum daily FDP when crew members are in an unknown state of acclimatisation shall be in accordance with the following table:
Table 3 Crew members in an unknown state of acclimatisation
| Maximum daily FDP according to sectors | ||||||
|---|---|---|---|---|---|---|
| 1–2 | 3 | 4 | 5 | 6 | 7 | 8 |
| 11:00 | 10:30 | 10:00 | 09:30 | 09:00 | 09:00 | 09:00 |
(3) The maximum daily FDP when crew members are in an unknown state of acclimatisation and the operator has implemented a FRM, shall be in accordance with the following table:
Table 4 Crew members in an unknown state of acclimatisation under FRM
The values in the following table may apply provided the operator’s FRM continuously monitors that the required safety performance is maintained.
| Maximum daily FDP according to sectors | ||||||
|---|---|---|---|---|---|---|

| 12:00 | 11:30 | 11:00 | 10:30 | 10:00 | 09:30 | 09:00 |
(c) FDP with different reporting time for flight crew and cabin crew. Whenever cabin crew requires more time than the flight crew for their pre-flight briefing for the same sector or series of sectors, the FDP of the cabin crew may be extended by the difference in reporting time between the cabin crew and the flight crew. The difference shall not exceed 1 hour. The maximum daily FDP for cabin crew shall be based on the time at which the flight crew report for their FDP, but the FDP shall start at the reporting time of the cabin crew.
(d) Maximum daily FDP for acclimatised crew members with the use of extensions without in-flight rest.
(1) The maximum daily FDP may be extended by up to 1 hour not more than twice in any 7 consecutive days. In that case:
(i) the minimum pre-flight and post-flight rest periods shall be increased by 2 hours; or
(ii) the post-flight rest period shall be increased by 4 hours.
(2) When extensions are used for consecutive FDPs, the additional pre- and post-flight rest between the two extended FDPs required under subparagraph 1 shall be provided consecutively.
(3) The use of the extension shall be planned in advance, and shall be limited to a maximum of:
(i) 5 sectors when the WOCL is not encroached; or
(ii) 4 sectors, when the WOCL is encroached by 2 hours or less; or
(iii) 2 sectors, when the WOCL is encroached by more than 2 hours.
(4) Extension of the maximum basic daily FDP without in-flight rest shall not be combined with extensions due to in-flight rest or split duty in the same duty period.
(5) Flight time specification schemes shall specify the limits for extensions of the maximum basic daily FDP in accordance with the certification specifications applicable to the type of operation, taking into account:
(i) the number of sectors flown; and
(ii) WOCL encroachment.
(e) Maximum daily FDP with the use of extensions due to in-flight rest Flight time specification schemes shall specify the conditions for extensions of the maximum basic daily FDP with in-flight rest in accordance with the certification specifications applicable to the type of operation, taking into account:
(i) the number of sectors flown;
(ii) the minimum in-flight rest allocated to each crew member;
(iii) the type of in-flight rest facilities; and
(iv) the augmentation of the basic flight crew.
(f) Unforeseen circumstances in flight operations — commander’s discretion
(1) The conditions to modify the limits on flight duty, duty and rest periods by the commander in the case of unforeseen circumstances in flight operations, which start at or after the reporting time, shall comply with the following:
(i) the maximum daily FDP which results after applying points (b) and (e) of point ORO.FTL.205 or point ORO.FTL.220 may not be increased by more than 2 hours unless the flight crew has been augmented, in which case the maximum flight duty period may be increased by not more than 3 hours;
(ii) if on the final sector within an FDP the allowed increase is exceeded because of unforeseen circumstances after take-off, the flight may continue to the planned destination or alternate aerodrome; and
(iii) the rest period following the FDP may be reduced but can never be less than 10 hours.
(2) In case of unforeseen circumstances which could lead to severe fatigue, the commander shall reduce the actual flight duty period and/or increase the rest period in order to eliminate any detrimental effect on flight safety.
(3) The commander shall consult all crew members on their alertness levels before deciding the modifications under subparagraphs 1 and 2.
(4) The commander shall submit a report to the operator when an FDP is increased or a rest period is reduced at his or her discretion.
(5) Where the increase of an FDP or reduction of a rest period exceeds 1 hour, a copy of the report, to which the operator shall add its comments, shall be sent by the operator to the CAA not later than 28 days after the event.
(6) The operator shall implement a non-punitive process for the use of the discretion described under this provision and shall describe it in the operations manual.
(g) Unforeseen circumstances in flight operations — delayed reporting The operator shall establish procedures, in the operations manual, for delayed reporting in the event of unforeseen circumstances, in accordance with the certification specifications applicable to the type of operation.
