Flight Duty Period (FDP)



(a)       The total duty periods to which a crew member may be assigned shall not exceed:

(1)   60 duty hours in any 7 consecutive days;

(2)   110 duty hours in any 14 consecutive days; and

(3)   190 duty hours in any 28 consecutive days, spread as evenly as practicable throughout that period.

(b)       The total flight time of the sectors on which an individual crew member is assigned as an operating crew member shall not exceed:

(1)   100 hours of flight time in any 28 consecutive days;

(2)   900 hours of flight time in any calendar year;  and

(3)   1 000 hours of flight time in any 12 consecutive calendar months.

(c)       Post-flight duty shall count as duty period. The operator shall specify in its operations manual the minimum time period for post-flight duties.

  1. But what happens when a pilot exceeds 100 hours while airborne? Is it an operator’s responsibility to self-impose a safety buffer before allowing a pilot to fly, or is there an option to exceed the 100 hours in exceptional circumstances??


    1. Peter,
      You asked the following:
      But what happens when a pilot exceeds 100 hours while airborne? Is it an operator’s responsibility to self-impose a safety buffer before allowing a pilot to fly, or is there an option to exceed the 100 hours in exceptional circumstances?

      Should in the course of executing a FDP, a pilot becomes aware that the limitations in ORO.FTL.210 (b) will be exceeded (after takeoff) due to unforeseen circumstances, this would fall under the authority permitted under commander’s discretion. In general, the flight may continue to the intended destination as long as the flight may be conducted safely, otherwise an alternate aerodrome should be selected. Should the conditions be known before takeoff, the flight should not be conducted, as this will violate the limitations as set forth in the regulations.

      Buffers is just one of several methods that may be used to mitigate the potential of violations, however, other methods do exist and in some circumstances may be more appropriate depending upon the specific situation. In general, the airline is responsible to continually monitor the situation and make recommendations to the commander who will have final authority once a flight becomes airborne. Additionally, the airline should not permit a crew to violate the FTLs as written in the certification specifications before takeoff.

      This is part of the duel responsibilities under ORO.FTL 110 and 115.

      Let me caution you, that I am not with the EASA, and Civil Aviation Authority or any Airline or Union, so my opinions may differ. Let me suggest that you check with any and or all of the above before forming a specific interpretation.

      I hope this aides you in your understanding.



  2. I see Duty Periods have accumulative maximum limits. Is there also a maximum per single Duty Period? Let’s say max 18 hours or so? Or is it without maximum per single Duty Period as long as the published accumulative maximum limits are not exceeded?

    thanks for your help


    1. The closest is Daily Flight Duty Period (FDP) Limits. (ORO.FTL.205 and ORO.FTL.220).
      FDP is different from Duty Time.
      FDP Starts at report for a duty period and ends when the last working flight arrives, positioning and ground time before FDP end is included.
      Duty time, starts at duty report and ends at duty release, all positioning and ground time during duty is included.

      With respect to cumulative limits (ORO.FTL.210), Duty Time limits for 7, 14 and 28 consecutive calendar days;
      as well as, Flight Time (Block) limits for 28 consecutive calendar days, 1 calendar year, and 12 consecutive calendar months; exist.

      There is sort of an implied daily duty limitation, when the determination of rest periods under ORO.FTL.235.
      Duty Time is used to calculate required rest under sections (a) & (b).

      Some Airlines have collective agreements for crew members, that establish daily duty limits.

      So, in short, under ORO.FTL, there are no specific daily duty limits.


  3. Is it possible to plan a ground training activity after a flight duty period? (eg e-learning after a flight taking into account the max duty period and starting the rest period at the end of the duty)

    Thank you for the help!


    1. Yes, it is legal.
      If the airline has assigned a crew member to a particular task after FDP and before rest, it is duty.
      As with any duty, time spent on duty may not be assigned concurrent with a rest period.

      The total time on duty is used to compute minimum required rest (ORO.FTL.235(a) & (b)).
      The total time on duty is also applied towards the cumulative duty limits in ORO.FTL.210(a).

      In the specific situation, the time on e-learning is not considered FDP so it is not regulated by the limitation in ORO.FTL.205.
