Operator Responsibilities

For the purpose of this subpart [Subpart FTL], the following definitions shall apply:

(1)       “acclimatised” means a state in which a crew member’s circadian biological clock is synchronised to the time zone where the crew member is. A crew member is considered to be acclimatised to a 2-hour wide time zone surrounding the local time at the point of departure. When the local time at the place where a duty commences differs by more than 2 hours from the local time at the place where the next duty starts, the crew member, for the calculation of the maximum daily flight duty period, is considered to be acclimatised in accordance with the values in the Table 1.

“B” means acclimatised to the local time of the departure time zone,

“D” means acclimatised to the local time where the crew member starts his/her next duty, and

“X” means that the crew member is in an unknown state of acclimatisation;

  1. It means that you cannot be awake more then 18 hours. You must count the 18 hours when you are on Standby or Reserve. Since the start of your STB to the end of your FDP, the elapsed time must be down the 18 hours

    Like

    1. Giulia,
      A Crew member (CM) assigned to Reserve (RSV) must be able to have a protected period of at least 8:00 for a sleep period during each calendar day the CM is to be on Reserve, meaning a period where the CM is “expected to be a sleep” and should not be contacted for an assignment. CS FTL.1.230(d). The 8:00 period has no defined time of day when it must be given, however, basic FRM principles should be followed to maximize alertness should notification for an assignment be given to a CM. The 8:00 sleep opportunity should be specified in the Operations Manual.

      If the CM is contacted for an assignment they must be given at least 10:00 notification before report. GM2 CS FTL.1.230(c), this time of notification ‘may’ include the 8:00 period.

      RSV is not considered rest so the time assigned to RSV is NOT to be as time towards the Recurrent Extended Recovery Rest (RERR) as defined in ORO.FTL.235(d) and GM1 CS FTL.1.230(c). The RERR must be no less than 36:00 with two local nights rest.

  2. What means “sector” exactly? Must the aircraft always go airborne or is a “return-to-ramp” with taxi phase only (e.g. due to technical problems) a sector as well. That would be interesting for calculating the max. FDP.

    1. Philipp,
      I believe that a sector is simply the number of times a crew who is working has taken off (gone airborne).
      The time to taxi-out and taxi-in for a gate return is block time, and should be applied towards the cumulative limitations.

      A flight that has taken off, and then diverts (either back to the original airport or to another airport) and then continues to the original destination will have one additional sector for the determination of the basic FDP limits.

  3. Hello, honestly I don’t understand very well the disruptive schedule.
    With a late finish/early start the rest has to include 1 local night. Here I see there are 2 types early type and late type. When it is one and when the other?
    Also it looks wird that if I finish my duty for example taking in consideration the late type at 0200 and my next duty will be at 0459 of the next day I don’t need for the rest a local night but if my late finish is at 0159 and next duty is at 0500 can’t be without a local night between. May be I’m missing something?

    Like

    1. There are indeed two types of definition of late finish and early start.
      The correct definition to be applied (Early type / Late type) is decided by your local CAA, and is applied to all operators whom are certified by that individual country. The definition is fixed and never varies.
      This is defined in ORO.FTL.105 (8) Disruptive Schedules, and further clarified in GM1 ORO.FTL.105 (8) Definitions.

      When a crew member (CM) transitions from a Late Finish to an Early Start or from a Night Duty to an Early Start, the intervening rest period must include a Local Nights Rest (LNR), Ref CS FTL.1.235 (a) (1).

      In the situation you are displaying:
      The CM Release at 02:00 the duty is a Night Duty (02:00 to 04:59) the next report is at 04:59 this is also a night duty.
      The transition rules do not apply as you are going from Night duty to Night Duty.
      Had the next duty started at 05:00 then you would required the LNR, as the CM would be transitioning from a Night Duty to an Early Start. Yes I know it is only 1 minute difference, and the rule is the rule, this seems to be one of the inconsistencies in the EASA FTLs.

      Consecutive Night Duties, however should apply appropriate Fatigue Risk Management Principles, this is referred to in two sections:
      CS FTL.1.205 (a) Night Duties
      and
      GM1 CS FTL.1.205(a)(2) NIGHT DUTIES.

  4. Hi,
    Can a “single day free of duty” means, for the purpose of complying with the provisions of Council Directive 2000/79/EC, a time free of all duties and standby consisting of one day and two local nights, which is notified in advance. A rest period may be included as part of the single day free of duty” be modified after the rosters have been published? What does it mean “notified in advance”? If you are in stand by and your called for a duty, can this duty be part of this single day and therefore the day off be cancelled ( and the the same time a new day off be notified)? Thank you very much.

      You asked the following Question:

      If you are in stand by and your called for a duty, can this duty be part of this single day and therefore the day off be cancelled ( and the the same time a new day off be notified)?

      “Rest Periods” (RP), “Recurrent Extended Recovery Rest Periods” (RERRP) , and “Single Day Free of Duty” (SDFD) are periods where a crew member (CM) is free from all duty (or the need to perform duty and are planned in advance (prospectively planned). A CM may be considered on SDFD RERRP and RP all at the same time as long as they individually meet the required criteria of duration and number of local nights.

      A CM assigned to Reserve or Standby at Home, is not considered to be at rest as they may be contacted during those periods for Duty should the need arise.
      The basic premise surrounding “Notified in advance” is to allow a CM to plan periods of sleep inorder to be adequately free from fatigue to perform the duties to perform Flight Duty. This means a airline cannot retroactively declare that a CM has a RERRP or SDFD just because they were not called out for a Duty period.

      However, CM may be re-assigned SDFD, RERRP as long as they meet the criteria concerning frequency (168 hours between RERRP ) and number of SDFD within a calendar month, as long as they will be notified in advance as to when the next RERRP/SDFD will be.

      I caution you, that this is my opinion alone, I am not with the EASA, or any CAA, or Airline or Union, so my opinion may differ.
      Please check with these groups to make sure you have the proper and approved interpretation.
      I am sure your airline should be able to help you further understand.

  5. Hello,
    Regarding the first question above: (Awake time definition)
    “It means that you cannot be awake more then 18 hours. You must count the 18 hours when you are on Standby or Reserve. Since the start of your STB to the end of your FDP, the elapsed time must be down the 18 hours”
    In this case the awake time is till end of FDP and not end of DP? Because there is no post-flight included? is that correct?
    Thanks for your help, Regards Marcel

    Like

    1. Marcel,

      The 18 hours awake rule can be found here:
      CS FTL.1.225 STANDBY
      (b) Standby other than airport standby:
      (1) the maximum duration of standby other than airport standby is 16 hours;
      (2) The operator’s standby procedures are designed to ensure that the combination of standby and FDP do not lead to more than 18 hours awake time;

      It is possible that a crewmember (CM) can be assigned to Standby (SBY) and is actually asleep during a portion of the period.
      For example:
      A CM is assigned SBY starting at 23:00 until 11:00. The during the period from 23:00 to 07:00, the CM is expected to try to get some sleep (that individual may try to begin sleep earlier than 23:00). Let us say the CM is contacted at 05:00 for a 08:00 FDP Start. The ‘Clock’ would begin at 05:00 and the CM would be expected to end the FDP no later than 23:00 ( 05:00 + 18:00 ).

      Our second example:
      A CM is assigned SBY starting at 23:00 until 11:00. The during the period from 23:00 to 07:00, the CM is expected to try to get some sleep (that individual may try to begin sleep earlier than 23:00). Let us say the CM is contacted at 08:00 for a 11:00 FDP Start. The ‘Clock’ would begin at 07:00 and the CM would be expected to end the FDP no later than 01:00 ( 07:00 + 18:00 ).

      Our third example:
      A CM is assigned SBY starting at 10:00 until 22:00. Since the SBY starts outside the 23:00 to 07:00 window, the 18 hour period would begin at the start of the SBY (10:00), regardless of the time of notification or the FDP start time; and the CM would be expected to end the FDP no later than 04:00 ( 10:00 + 18:00 ).

      If I understand the regulation properly, the 18:00 time limit cannot be extended as it is part of the criteria for extensions due to unforeseen circumstances – commanders discretion (AMC1 ORO.FTL.205(f)) and (GM1 CS FTL.1.225(b)(2)).

      Different Airlines may have different procedures, so you should check with your airline as to when the 18:00 period is expected to begin for a specific example.

  6. Is the time for travelling from a place to rest away from home base to a place where to commence a flight calculated in the fdp? Is there a maximum limit of time for this kind of transfert?

    1. If the travel time is local in nature (less than or equal 30 minutes) it is included when calculating the rest period under ORO.FTL.235,

    1. Simon, you asked the following:
      Is there a time that you should be off duty prior to a day off.
      For example my company will give me a checkout of 23.59 at my home base preceeding my day off starting at 00.00?

      EASA FTL does not regulate “single days free of duty”.
      (23) “single day free of duty” means, for the purpose of complying with the provisions of Council Directive 2000/79/EC, a time free of all duties and standby consisting of one day and two local nights, which is notified in advance. A rest period may be included as part of the single day free of duty;

      “Days off” would be handled via national legislation.

      However, there are rest requirements that must be met.
      Under ORO.FTL.235 (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.

      The rest period, as required is measured from release of the previous duty period to the report for the next duty period.
      It must be a single continuous period, of no less than 36:00 and must contain two LNR. Travel time from release to you home is part of a rest period. This is consistent with the following definitions:

      (16) “local night” means a period of 8 hours falling between 22:00 and 08:00 local time;
      (21) “rest period” means a continuous, uninterrupted and defined period of time, following duty or prior to duty, during which a crew member is free of all duties, standby and reserve;

      I believe that your scenario is legal under EASA FTL, however, you should check your company manuals (OM), Union Documentation and National Legislation to seen if there are other requirements. Ask your airline, I am sure they can help you.

  9. Hello, I have a question regarding FDP: We receive our documents from the operator a few hours before the flight and we are urged to prepare the flight in our hotel (we don’t stay at home base) because the 1 hour preparation time at the airport is not enough (security, walking to aircraft, printing the documents etc…).
    Would this legally be a split duty? How would you define this preparation time before the flight (followed by a transportation of about 30 min to the airport)?
    Also what if we do a briefing in the hotel before the flight because we have no briefing room at the airport? This is duty time or FDP?
    Many thanks for your opinion.

    1. Gerog,
      Based upon the definitions (ORO.FTL.105):
      (10) “duty” means any task that a crew member performs for the operator, including flight duty, administrative work, giving or receiving training and checking, positioning, and some elements of standby;
      (11) “duty period” means a period which starts when a crew member is required by an operator to report for or to commence a duty and ends when that person is free of all duties, including post-flight duty;

      The time when you begin to prepare for the flight is the start of the Duty Period / FDP.
      So in the case presented, in the hotel, you will begin duty once you start preparing paperwork / briefing for the flight (whichever is earlier).
      The duty includes the time when everyone meets in the lobby to board the transportation to the airport, travel to the airport, go through security, arrive at the gate, prepare and inspect the aircraft, board the passengers and depart the gate.
      I would not consider it a split duty.

      If the operator is expecting the crew to begin the day in the hotel, then they need to meet the obligations in ORO.FTL.110(c) specify reporting times that allow sufficient time for ground duties;

      Starting the duty earlier, also reduces the time available for a rest period / sleep opportunity.

      Of course this all goes out of consideration, if individuals volunteer to do the work at the hotel as long as the report for the duty, fit for duty.

  10. And my second question: How would you define a debriefing time after a flight (during line training environment) and after the 30min transportation to the hotel? Because this transportation time to the hotel is taken already from the min 10h rest time? What if it is followed again by a duty? (Assumed that debriefing time is a duty time?)

    And if I am waiting for a taxi after a flight to position to my hotel, this waiting time is still duty time right?

    And what about the time to prepare for a new airport to fly from? Would this all have to be done in the usual one hour before the flight? Could I ask the operator to show me how he defined this time

    Many thanks,
    Georg

    1. Georg,
      Waiting for a Taxi is not duty, it should be part of the travel time.

      Debrief, as I am aware of, is the formal conclusion of duty, and the start of a rest period.
      So you block in at the airport, conclude post flight duties, travel to the hotel, attend a post training debrief session, and finally declare an end duty? I would consider that as all duty.

      New Airport, Duty begins when a crew member presents themselves at the designated location to begin duty. It must be of sufficient duration to include all pre-flight activites (ORO.FTL(c)). Yes, the operator should be able to provide this information, based upon Airport, Aircraft Type, and Type of Operation.

      1. WxMan, thanks for your thoughts.

        I am just wondering, what makes you believe that waiting for local transportation after th elfight to go to the company accommodation/ hotel belongs to travel time (if not more than 2x 30min included in the 10h rest time)?
        Is there any specification of such waiting time I. The FTL?
        (Another thing, waiting as crew at immigration is this duty time as well probably?)

        Now arriving to the hotel, the Line training captain would like to sit down and brief our training flight for 30 minutes, how would that be counted? Can the duty period be interrupted (by the 30 min local transportation?)?

        So my total duty would be in this case minus the local travel time?

        And going back to the airport, briefing together with the cabin crew at the hotel is the start of the FDP. But than this 30min local transport to the airport is included in the 10h rest time right – would you subtract this time from the FDP or once FDP has started its running?

        Second scenario: no briefing at the hotel but we depart 50 min before check in to the airport (regular travel time 30 min) to have 20 min for safety in case of traffic. Would this 20 min be travel time as well if we don’t spend it in the transportation?

        And are you aware any definition of the preflight duties?
        Would you include everything there (in Low Cost operation pilots have to do now a days everything….) such as printing the documents, calling for fuel, checking notams and weather, walking to the aircraft, passport control, security checks, preparing the aircraft, fueling, boarding, briefings, everything?

        I will let you knew what the operator will answer me when I ask him how he calculated the check in time 😉

        We have officially one hour but we check in 1:30 before the flight…..
        And we are for sure not the only company doing this.

        The entire time from in-time to the end of the line training session is duty, including the travel time to the hotel. Your rest period may never be less than your duty time ( report time at the start of the day through the end of the line training ) as defined in ORO.FTL.235.

        (Another thing, waiting as crew at immigration is this duty time as well probably?)

        Immigration (and customs), yes, I can see that as part of duty. Should be built in as part of the debrief process at the end of a duty period.
        Waiting for the Taxi, this should have been built into the normal travel time. Extra long travel time should not prevent a crew member in a rest period
        from actually getting the minimum of 8:00 sleep opportunity. Lets say the rest period is just 10:00, Subtract the minimum travel time both ways (2*0:30), that leaves 9:00, now subtract the minimum time for physiological needs (1:00), 8:00 which is the minimum sleep opportunity.with an extra 0:05 travel time each way, the minimum rest period would need to be increased by 0:10. You should not have a problem when the rest periods are longer, lets say 12:00, subtract the 1:10 travel, and the 1:00 physiological needs, the remainder is 9:50 which is longer than the minimum 8:00 sleep opportunity.

        And going back to the airport, briefing together with the cabin crew at the hotel is the start of the FDP. But than this 30min local transport to the airport is included in the 10h rest time right – would you subtract this time from the FDP or once FDP has started its running?

        FDP and Duty start at report in the Hotel. Rest period ends at report. Travel time is part of the Duty and FDP. Once Started it will continue until Release from duty, or last working arrival for FDP.

        Second scenario: no briefing at the hotel but we depart 50 min before check in to the airport (regular travel time 30 min) to have 20 min for safety in case of traffic. Would this 20 min be travel time as well if we don’t spend it in the transportation?

        Correct, it is just part of the travel time, it may also be considered rest. Rest ends once the crew begins working at the designated reporting location.

        And are you aware any definition of the preflight duties?
        Would you include everything there (in Low Cost operation pilots have to do now a days everything….) such as printing the documents, calling for fuel, checking notams and weather, walking to the aircraft, passport control, security checks, preparing the aircraft, fueling, boarding, briefings, everything?

        I will let you knew what the operator will answer me when I ask him how he calculated the check in time 😉

        I will admit, I do not know everything that is required to be done, but the operator is responsible under ORO.FTL.110(c) to provide adequate ground duty time.

        We have officially one hour but we check in 1:30 before the flight…..
        And we are for sure not the only company doing this.

        So are you on the clock officially? If you are reducing the rest period below requirements it could be a problem.

  11. Hi,
    Disruptive schedule; Early type:
    When, other than airport standby, (home standby), starts 0340. Would you consider this a disruptive schedule?
    Will it count as night duty, even if not called?
    Best regard Rolf

    1. Technically no.

      The definitions in ORO.FTL.105 provides:

      (8) “disruptive schedule” means a crew member’s roster which disrupts the sleep opportunity during the optimal sleep time window by comprising an FDP or a combination of FDPs which encroach, start or finish during any portion of the day or of the night where a crew member is acclimatised. A schedule may be disruptive due to early starts, late finishes or night duties.

      While airport standby is considered FDP, standby (home standby) is not. and the definition above clearly discusses FDP only when making the determination of disruptive schedules.

      Still, the Airline needs to also view the rest periods that exist on the crew members roster with respect to the WOCL to see if the schedule could be considered disruptive as well.

  12. Hi!

    I have a question about reserv and stadby duty. If I have a standby for example from 8-17. Can they call me out for a flight that has a planned checkout after 17 ?

    Best regards

    1. Yes, under certain conditions:

      The limit to remain on Airport Standby (ASB) and Home Standby (SBY) is governed under CS FTL.1.235 (a) and (b) is 16:00.
      So, in your example a SBY that begins at 08:00 must at or before 24:00.

      Should a CM be notified of a DUTY before the scheduled end of the planned SBY, the SBY may be extended, and will end once the CM reports for DUTY. The SBY must end within 16:00 from its start. Should the CM be assigned to a FDP after serving more than 6:00 on SBY the scheduled FDP must not exceed the scheduled limit, less the amount of SBY beyond 6:00.

      Should a CM complete a SBY without being notified of a DUTY before the end of the SBY, that CM is now on a rest period and is not to be contacted during the rest period.

      You should have a discussion with your airline officials as they may have a different opinion.

  13. Hello, what is mean “8 hours falling between 22:00 and 08:00 local time”? Is it mean 8 hours slepping time? After night duty is it OK to next duty that start at 06:00 local? Because when duty starts 6 am you have to wake up early?

    1. If you have just completed a duty that touches/overlaps any portion of the time from 02:00 to 04:59 (night duty) ORO.FTL.105 (9), that duty must be followed by a rest period of no less than 10:00. If the next duty period begins between 05:00 to 06:59 (05:59 for early type) ORO.FTL.105 (8); the rest period after the night duty must also include a Local Nights Rest (LNR). A LNR must include any 8:00 between 22:00 and 08:00, the 8:00 is rest, not necessarily Sleep ORO.FTL.105 (16). A Rest Period ends when a crew member reports for duty; not when the crew member wakes up, ORO.FTL.105 (21).

      So if I understand your example correctly:
      1) Duty #1 ends at 02:01 day 1. The next FDP must not begin any earlier than 12:01 day 1 (2:01 + 10:00) as per ORO.FTL.235(b).
      2) Duty #2 starts at 06:15, it must be on day 2 to comply with 1). Duty #2 is an early start, in order to transition from a late finish/night duty the intervening rest period must include 1 LNR as per CS FTL.1.235(a)(1). The earliest the next LNR may commence is 22:00 day 1 and it may not end any earlier than 06:00 day 2.

      So the minimum rest period is from 02:01 day 1 to 06:00 day 2, a duration 29:59. In the case provided, the intervening rest period is 30:14.

      I hope this helps you understand.
