Module 2:

Concept Model


Basic DefinitionsLocal Day means a 24-hour period commencing at 00:00 local time.

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.

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.

Sleep opportunitymeans a period of time when a crewmember is provided and allowed to be in a suitable accommodation to rest in.

Suitable accommodation means, for the purpose of standby, split duty, and rest, a separate room for each crew member located in a quiet environment and equipped with a bed, which is sufficiently ventilated, has a device for regulating temperature and light intensity, and access to food and drink.


AcclimatizationA CM who is in an acclimated state remains in an acclimated state as long as they remain within a zone +/-2 hours either side of the time zone in which the CM is acclimated to.

State of Acclimatization: (D) Acclimated to Departure - occurs when a CM has spent sufficient time within a timezone to become

acclimated to the timezone for departure. (B) Acclimated to Previous Acclimated Time Zone – occurs when a CM has spent insufficient time within a

timezone to begin the acclimatization process. (X) Unknown - when a CM has entered a new timezone and has begun the acclimatization process but has not

spent sufficient time to adjust to the local timezone.


AcclimatizationExample: a CM acclimated to Paris (UTC + 1), remains acclimated as long as they remain within the following time zones: UTC -1, UTC, UTC + 1, UTC + 2, UTC + 3 at the conclusion of the duty period. Jeddah (UTC + 3) is acclimated, while Tehran (UTC + 3:30) will require the crewmember to become acclimated.

AcclimatizationAcclimatisation process is also known as re-adaptation.

Flying across time zones exposes the circadian body clock to sudden shifts in the day/night cycle. Because of its sensitivity to light and (to a lesser extent) social time cues, the circadian body clock will eventually adapt to a new time zone. The acclimatisation process follows Table 1 defined in ORO.FTL.105 Definitions


Time difference (h) between reference time and local

time where the crew member starts the next

duty

> 9 and ≤ 12 B X X X D

AcclimatizationTime difference between reference time zone and local time, is simply the difference between the time zone where the CM was last acclimated to, and the time zone where a crewmember will begin the next duty.

Example: CM is acclimated to Paris (UTC + 1) (Reference Time) and will begin the next duty period in Chicago (UTC -6), whereby the Time Difference is 7:00.

The time elapsed since reporting at reference time to the time of report of the next duty. A conversion to UTC date time will be required to calculate the elapsed time.

A Report in Paris on 15-Feb-2017 at 10:00 (Local) is 15-Feb-2017 at 09:00 (UTC), the next report in Chicago is on 16-Feb-2017 at 20:00 (Local) is 17-Feb-2017 at 02:00 (UTC), whereby the time elapsed is 40:00. Case #1: Since the elapsed time is less than 48:00 (Row 3, Column 1) the crewmember remains

acclimated to Paris time (UTC + 1). Case #2: Had the departure in Chicago been postponed 24 hours, the elapsed time would be 64:00,

the CM has now moved into an unknown state of acclimatization (x) (Row 3, Column 2). Case #3: Had the departure in Chicago been postponed 60 hours, the elapsed time would be

100:00, the CM has now moved into an acclimated state of acclimatization (Row 3, Column 4). The CM is acclimated to Chicago Time (UTC -6),


AcclimatizationReference Time for the next departure is defined as follows:1. When a CM begins the next duty period in an (B) Acclimated to Previous Acclimated Time

Zone state to the reference time is the time zone where that cm was last acclimated to. 2. When a CM begins the next duty period in an (X) Unknown state there is no reference time. 3. When a CM begins the next duty period in an (D) Acclimated to Departure state the

reference time is the local time zone where the duty period begins. 4. Should the CM remain within the zone of acclimatisation, the reference time is the local

time zone where the duty period begins.

Author’s note: Best practices suggest that operators use the time zone where the CM is currently acclimated to when evaluating under conditions 1 and 4 above.


Window of Circadian Low (WOCL):

Window of circadian low means the period between 02:00 and 05:59 hours in the time zone to which a crew member is acclimatised

Shall be based upon the OCM's reference time zone (RTZ).


Flight Duty Period (FDP)

FDP

Duty TimeRelease Time

Report Time

Note:Difference between Duty Time and FDPOperational Ferry

For an OCM assigned to a duty period that contains flight time:• The start of the FDP is at the report time (UTC) of the duty period.• The end of the FDP is at the arrival time of the last operating (working) flight

(UTC) before the start of a rest period.• Ferry Flights are considered working flights.

Rest Period and BreaksRest Period:A Rest Period begins when a crew member is released from duty until the crew member reports for the next duty. When the airline is responsible to provide a rest accommodation, Travel time to/from the accommodation, Physiological needs and Sleep opportunity must be considered.


Rest Period and BreaksBreak:A Break - is not considered a Rest Period, it is used to extend FDP limitations using Split Duty rules. The minimum time for a Duty Break is 3 hours.


Author’s note: The operator should specify the times in its Operations Manual (OM) the minimum durations of:• Post-Flight Duty• Pre-Flight Duty

Travel Time to/from accommodation, The operator should consider airport, time of day, aircraft type when specifying the minimums above.

The absolute minimum ground time between two flights that may be considered a break is 3:30,

Break = Ground Time – (Post-Flight Duty + Pre-Flight Duty + Travel Times)3:00 = 3:30 – 0:30,

However the ground time will most likely increase due to values in the OM,

Example: 3:00 = 5:00 – (0:30 + 1:00 + 0:15 + 0:15)

Rest Period and BreaksLocal Night Rest (LNR):• Must include:

o 8 consecutive hours o that starts at or before 00:00 (local time) and ends at or after 06:00 (local time)


Example 1 – show a 10 hours rest period from 22:00 to 08:00, this qualifies as a LNR.

Example 2 – has a 10 hour rest period with 8 hours during the LNR period from 00:00 to 08:00, the rest from 08:00 to 10:00 is not applied towards the LNR.

Example 3 – has a 10 hour rest period with 8 hours during LNR period from 22:00 to 06:00, the rest from 20:00 to 22:00 is not applied towards the LNR

Example 4 – has a rest period from 01:00 to 06:00 the following day, the rest from 01:00 to 08:00 is not applied towards the LNR since it is insufficient in duration, the rest from 08:00 to 22:00 also is not applied towards the LNR, the rest from 22:00 to 06:00 the next days is applied toward the LNR, it falls within the window and is of sufficient duration.

Example 5 – has a rest period from 07:00 to 06:00 the following day, the rest from 07:00 to 08:00 is not applied towards the LNR since it is insufficient in duration, the rest from 08:00 to 22:00 also is not applied towards the LNR, the rest from 22:00 to 06:00 the next days is applied toward the LNR, it falls within the window and is of sufficient duration.

Rest Period and Breaks


Example 6 – has a rest period from 06:00 to 05:00 the following day, the rest from 06:00 to 08:00 is not applied towards the LNR since it is insufficient in duration, the rest from 08:00 to 22:00 also is not applied towards the LNR, the rest from 22:00 to 05:00 the next days is not applied towards the LNR since it is insufficient in duration.

Example 7 – has a rest period from 11:00 to 06:00 the following day, the rest from 11:00 to 22:00 is not applied towards the LNR, the rest from 22:00 to 06:00 the next days is applied toward the LNR, and it falls within the window and is of sufficient duration.

Example 8 – has a rest period from 00:00 to 12:00 the following day, the rest from 00:00 to 08:00 is applied towards the LNR since it is of sufficient in duration, the rest from 08:00 to 22:00 is not applied towards the LNR , the rest from 22:00 to 08:00 the next days is applied toward the LNR, it falls within the window and is of sufficient duration, the rest from 08:00 to 12:00 is not applied toward the LNR. The total amount of rest is 36 hours with 2 LNR‘s.

Example 9 – has a rest period from 01:00 to 13:00 the following day, the rest from 01:00 to 08:00 is not applied towards the LNR since it is of insufficient in duration, the rest from 08:00 to 22:00 is not applied towards the LNR , the rest from 22:00 to 08:00 the next days is applied toward the LNR, it falls within the window and is of sufficient duration, the rest from 08:00 to 13:00 is not applied toward the LNR. The total amount of rest is 36 hours with 1 LNR

Rest Period and Breaks


Extended Recurrent Recovery Rest (ERRR):Is a rest period that meets the following conditions:

• It is no less than 36 hours in duration and• It contains 2 consecutive LNR’s

Authors Note: Best practices suggest that ERRR’s should be given in the home base environment whenever possible.

Applied Crew SchemesCrew Schemes are also known as crew complements. The positions Captain (CA) and First Officer (FO), refers to individuals who hold the Required Qualifications to Operate in that specific position, versus the Rank of the individual. Individual Airline designations may apply differently.

Relief FCM’S are required to meet the appropriate qualifications for the inflight duties to be performed in accordance to ORO.FC.A.201.

Standard Flightcrew:• Flight operations which operate with only one (1) Captain (CA) and one (1) First Officer (FO)• Any aircraft that lacks a Class 1, 2 or 3 on-board rest facility, or• Any FDP scheduled with more than three (3) operational flights.

Augmented Flightcrew:• All flight operations within the FDP must operate with at least, two (2) Captains (CA) and one (1) First Officer (FO)• Augmented Flightcrew must be assigned to an aircraft that has a Class 1, 2 or 3 on-board rest facility.• Augmented Flightcrew must be assigned to a FDP scheduled with less than four (4) operational flights.

Heavy Flightcrew:• All flight operations within the FDP must operate with two (2) Captains (CA) and two (2) First Officers (FO)• Heavy Flightcrew must be assigned to an aircraft that has a Class 1, 2 or 3 on-board rest facility.• Heavy Flightcrew must be assigned to a FDP scheduled with less than four (4) operational flights.


Applied Crew SchemesCrew Schemes are also known as crew complements.

Standard Cabin crew:• Flight operations, which operate with the minimum required cabin crew, based upon seating capacity and operating

requirements.• Any aircraft that lacks a Class 1, 2 or 3 on-board rest facility. or• Any FDP scheduled with more than three (3) operational flights.

Augmented Cabin crew:• Flight operations which operate with the minimum required cabin crew based upon seating capacity and operating

requirements plus additional cabin crew and allows for each cabin crewmember to be relieved of required tasks during a flight in accordance to CS FTL.1.205 Flight Duty Period (FDP) (c)(3)

• Augmented Cabin crew must be assigned to a FDP scheduled with less than four (4) operational flights.


Applied Crew SchemesApplied Flightcrew Member Schemes All operational flights contained within a FDP shall be evaluated to determine the minimum applied scheme as follows:

This will avoid circumvention of Flight Time / Flight Duty Time Limitations and Rest Requirements.

FDP with more than 3 legs scheduled, must apply • 2 Pilot Schemes (Un-augmented).

In-flight Rest RequirementsPermits extension above scheduled FDP limits. May not be combined with Split Duty Extensions.

Augmented and Heavy Flightcrew Schemes:• An inflight rest period is only applied during cruise, not during the take-off or landing phases of a flight.

o Takeoff phase - is generally the first 30 to 45 minutes of a flight.o Landing phase - is generally the last 30 to 45 minutes of a flight.

• An inflight rest period for each flightcrew member must allow for 90 minutes of rest. o Best practices suggest that the inflight rest periods also allow for the impacts of 'sleep inertia', 10-15 minutes.

• An inflight rest period for the flightcrew members performing the aircraft landing on the last flight in the FDP must allow for two (2) hours of continuous inflight rest.

In-flight Rest Facilities:• ‘Class 1 rest facility’ means a bunk or other surface that allows for a flat or near flat sleeping position. It reclines to at

least 80° back angle to the vertical and is located separately from both the flight crew compartment and the passenger cabin in an area that allows the crew member to control light, and provides isolation from noise and disturbance;

• ‘Class 2 rest facility’ means a seat in an aircraft cabin that reclines at least 45° back angle to the vertical, has at least a pitch of 55 inches (137.5 cm), a seat width of at least 20 inches (50 cm) and provides leg and foot support. It is separated from passengers by at least a curtain to provide darkness and some sound mitigation, and is reasonably free from disturbance by passengers or crew members;

• ‘Class 3 rest facility’ means a seat in an aircraft cabin or flight crew compartment that reclines at least 40° from the vertical, provides leg and foot support and is separated from passengers by at least a curtain to provide darkness and some sound mitigation, and is not adjacent to any seat occupied by passengers.


In-flight Rest Requirements


Example 1: legal for a 3 pilot flightcrew, complies with the requirement for 2 hrs inflight rest in the FDP and a 90 minute inflight rest for the other pilots, the inflight rest do not overlap.

Example 2: legal for a 4 pilot flightcrew only, the inflight rest periods must overlap.

Authors Note: The final determination of the minimum inflight rest for the pilot who will be performing monitoring duties on the flight during landing is by the individual regulatory agency, in some cases 1:30 may be permissible, while in other cases, just like the pilot whom will be performing the actual landing, 2:00 may be required. Readers should check with the Airline and or the proper governing agency, for the proper determination concerning minimum inflight rest for these individuals.

Night Duty Early Start / Late Finish


Night Duty Period (NDP):• Night Time is defined as 02:00 and 04:59 in the time zone to which the

crewmember is acclimatised.• Is a Duty Period, which infringes upon any portion of Night Time.• Consecutive NDPs are those, which occur during the Night Time on consecutive

calendar days.

Early Start: Is dependent upon the type of disruptive schedule being used:

• For Early Type:o Early Time is defined as 05:00 and 05:59 in the time zone to which the

crewmember is acclimatised.• For Late Type:

o Early Time is defined as 05:00 and 06:59 in the time zone to which the crewmember is acclimatised.

Is a Duty Period which starts (Reports) during the period of Early Time.



Late Finish: Is dependent upon the type of disruptive schedule being used:

• For Early Type:o Late Time is defined as 23:00 and 01:59 in the time zone to which the

crewmember is acclimatised.• For Late Type:

o Late Time is defined as 00:00 and 01:59 in the time zone to which the crewmember is acclimatised.

Is a Duty Period which ends (Releases) during the period of Late Time.

Operating Flight

Split Duty:• Is a FDP which contains a Break of at least 3 hours in a ground rest facility.• May be applied to a FDP at any time of the day.• Break is less than a Required Rest Period.• Break is considered FDP as well as Duty.• Break requires a Suitable Accommodation if the Break is 6 hours or more, or touches the WOCL.• FDP is measured from Report to Arrival of Last Operating Flight.• Is only applied to duties that operate under Standard Crew Schemes.

• Permits extensions above the scheduled FDP limits by 50 % of the break that does not touch the WOCL with a maximum extension of 3:00 when a suitable accommodation is not provided.

• Permits extensions above the scheduled FDP limits by 50 % of the break when a suitable accommodation is provided.
