Example of ORO.FTL.110 Operators responsibilities.

The following aid has been developed to provide some suggestions for meeting Operator responsibilities.

Not all examples have been presented, and not all examples need to apply to all operations or your particular airline.

Each airline must develope the appropiate procedures.


Operator Responsibilities

An operator shall:

Metric

Description

a) publish duty rosters sufficiently in advance to provide the opportunity for crew members to plan adequate rest;

7 Days Off Required each Calendar Month

Rosters for all Crew Fleets will be published with a minimum of 14 days’ notice from the start of the publication month. Crew shall be given days free of all duty and standby, which are notified in advance, as follows:

a) At least seven local days off in each calendar month, this may include any rest periods required by law.

b)   ensure that flight duty periods are planned in a way that enables crew members to remain sufficiently free from fatigue so that they can operate to a satisfactory level of safety under all circumstances;

Limit of number sectors in a rolling 24 hour period for

un-augmented crew complements.

Limit the number of sectors to 10 in any 24:00 period.

c) specify reporting times that allow sufficient time for ground duties;

Minimum Brief Time

1) The Minimum Brief Time should allow for sufficient time for the execution of all pre-flight duties.

2) Factors to consider include:

a) Type and size of aircraft

b) Type of operation

c) Airport conditions

d) take into account the relationship between the frequency and pattern of flight duty periods and rest periods and give consideration to the cumulative effects of undertaking long duty hours combined with minimum rest periods;

Minimum Sleep Opportunity

When away from base, in the case when the rest period earned by a crew member is 10 hours, and suitable accommodation is provided by the operator then that rest period may be reduced by one hour.

In such circumstances, if the travelling time between the aerodrome and the accommodation is more than 30 minutes each way then the rest period must be increased by the amount the total time spent travelling exceeds one hour.

The room allocated to the crew member must be available for occupation for a minimum of 8 hours. This sub paragraph does not apply to rest periods that exceed 10 hours.

Long Duty Day

1)     Duty hours exceeding twelve (12) hours thirty (30) minutes (“Long Duty Day” shall be planned with a Rest Period of fifteen (15) hours.

2)     Following a Long Duty Day, crew members will not be rostered another consecutive Long Duty Day, unless called from Standby or Reserve.

Maximum Duties on the same Calendar Day

Crew members will not be planned to clear and report in the same day (24 hours midnight to midnight).

e) allocate duty patterns which avoid practices that cause a serious disruption of an
established sleep/work pattern, such as alternating day/night duties;

Short Haul Duty Pattern

In order to roster duty patterns which avoid practices that cause a serious disruption of established sleep/work pattern, such as alternating day/night duties, when reporting for short haul operations the first report times of each Trip in a Block of Work will be kept within a 8-hour band of each other.

Mixed Duties

When a crew member is required to report for duty in advance of the stipulated report time for a scheduled flight, to carry out a task at the behest of an employer, then the time spent on that task shall be part of the subsequent FDP.

Mixed Simulator and Aircraft Flying

When a flight crew member flies in the simulator, either on a check or training flight, or as a Training Captain or Instructor, and then within the same duty period flies as a crew member on a public transport flight, all the time spent in the simulator is counted in full towards the subsequent FDP.
Simulator flying does not count as a sector, but the allowable FDP shall be calculated from the report time of the simulator detail.

Block of Night Duties / Early Starts / Late Finishes

Sleep deprivation, leading to the onset of fatigue, can arise if a crewmember is required to report early for duty, or finishes a duty late, on a number of consecutive days.

The following restrictions shall apply for crew members to any sequence of duties involving 4 or 5 duties occurring in any part of the period 0100 to 0659 local time between consecutive extended recovery rest periods:

a)    The minimum rest period before the start of such a series of duties shall be 36 hours.

b)    After the sequence crew members shall have 2 local days, which shall not be less than 60 hours. Where a sequence of six days is involved this time off shall be at least 70 hours.

c)     Should a crew member be scheduled for any duty that occurs during any part of the period 0200 and 0459 local time, for a minimum of 2 and a maximum of 3  consecutive nights, then crew members must be free of all duties by 2100 hours local time before covering the block of consecutive night duties, such that the crew members can take a rest period during a local night.

d)    Rotations where the operator provides accommodation at home base cannot be planned consecutively (Back 2 Backs).

e)    A maximum of 3 sectors or a maximum of 4 sectors with an FDP not exceeding 10 hours will be planned prior to and following extended recovery rest periods.

f)     A series of duties may not contain more than four consecutive 4 sector days

Long Night Duties

Sleep deprivation, leading to the onset of fatigue, can arise if a crewmember is required to report early for duty, or finishes a duty late, on a number of consecutive days.

The following restrictions shall apply for crew members to any sequence of duties involving 4 or 5 duties occurring in any part of the period 0100 to 0659 local time between consecutive extended recovery rest periods:

a)  When rostering night duties of more than 10 hours (referred to below as ‘long night duties’), it is critical for the crew member to obtain sufficient sleep before such duties when he/she is adapted to being awake during day time hours at the local time where he/she is acclimatized. The following principles will be applied to the rostering of long night duties:


i.   In a series of consecutive Night Duties departing from base, an FDP of 10 hours or more shall not be rostered following an extended rest period on a planned basis.


ii.  The planned report times of each trip at Base, on consecutive days in a series of duties, will not exceed a 8-hour time band from the previous report time at base.


iii.  
Starting a block of night duties with a shorter FDP

Block of 4 or 5 Night Duties

Sleep deprivation, leading to the onset of fatigue, can arise if a crewmember is required to report early for duty, or finishes a duty late, on a number of consecutive days. The following restrictions shall apply for crew members to any sequence of duties involving 4 or 5 duties occurring in any part of the period 0100 to 0659 local time between consecutive extended recovery rest periods:

a)   However, crew members who are employed on a regular Night Duty for a maximum of 5 consecutive local nights will work to the following:


i.  The minimum rest period before the start of such a series of duties is 24 hours.


ii.  
The duty will not exceed 8 hours, irrespective of the sectors flown.

            iii.   At the finish of such a series of duties, crew members will have a minimum of 54 hours free from all duties.

Eastward-Westward Transitions

1)   ‘Eastward-Westward / Westward-Eastward transitions’  cannot be planned consecutively unless rostered from standby or reserve.

2)   The minimum separation from the end of a rotation crossing 4/6 or more time zones in one direction and the next rotation crossing 6/4 or more time zones in the opposite direction will include at least 3 local nights rest.

a)     The rest period after the first rotation must be in compliance with CS FTL.1.235 (b)(3)(i).

b)      At least one additional rest period before the start  of the 2nd rotation must include a local nights rest, when the total number of local nights rest provided in the first rest period is less than 3.

Scheduling Buffers

1)  Provide buffers to minimize the impact of FDP / Duty period extensions and the possible reduction of required  rest periods.

2)  Such buffers include:

a)      FDP buffers

b)      Duty period buffers

c)       Flight time buffers

d)      Rest buffers

e)      Intervening ground time buffers

 

3)  Buffers should consider type of operation, airport conditions and likelihood of delays and disruptions.

Required Rest following Training

If a crewmember is required to deliver/undertake training the following shall apply:

a)   If a crewmember completes between 1-4 days of training they will receive a minimum of 12:00 Hrs. and a local nights rest following the last training duty prior to performing duties as an operating crewmember.

b)   If a Crewmember completes between 5 and 7 days training they will receive a minimum of 1 day (2 local nights 36 Hours) off following the last day of training prior to performing duties as an operating crewmembers.

f)   comply with the provisions concerning disruptive schedules in accordance with ARO.OPS.230;

 

 

g)  provide rest periods of sufficient time to enable crew members to overcome the effects of the previous duties and to be rested by the start of the following flight duty period;

 

 

h) plan recurrent extended recovery rest periods and notify crew members sufficiently in advance;

Planned Recurrent Extended Recovery Rests

Roster stability and the protection of Days Off are maintained within a crewmembers roster following publication unless called from standby, or due to operational requirements or agreements of the crew. In order to provide rest periods of sufficient time to enable crew members to overcome the effects of the previous duties and to be rested by the start of the following flight duty period.

In order to plan recurrent extended recovery rest periods and notify crew members sufficiently in advance the following applies:

a)  A planned rest period may be included as part of a day off.

b)  Crew members shall:

i. have 2 consecutive days off in any consecutive 14 days following the previous 2 consecutive days off,

ii.  except that for crew members away from base the requirement for these 2 days may be deferred and discharged as 3 consecutive days off immediately upon return to base.


i)   plan flight duties in order to be completed within the allowable flight duty period taking into account the time necessary for pre-flight duties, the sector and turnaround times;

Minimum Ground Time Between Flights

1)        Schedules should allow for flights to be completed within the maximum permitted flight duty period and flight rosters should take into account the time needed for pre- flight duties, taxiing, the flight- and turnaround times.

2)       factors to consider:

a)      Type and size of aircraft

b)      Type of operation

c)       Airport  conditions

j)    change a schedule and/or crew arrangements if the actual operation exceeds the maximum flight duty period on more than 33% of the flight duties in that schedule during a scheduled seasonal period.
