Concept Model


AcclimatisationAcclimatised means the physiological and mental state of a crew member whose bio-rhythms and bodily

functions are considered aligned with local time.Acclimatised time means the time at the location where the flight crew member is acclimatized.

For the purpose of determining the FDP Table start time, Canada will be considered to encompass 5 time zones: Pacific, Mountain, Central, Eastern, and Atlantic. The Newfoundland Time zone is considered to be included in the Atlantic Time zone.

A crewmember is deemed to be in an acclimated state when the following conditions are satisfied:

• when the time zone difference between local time and last acclimatised time does not exceed 4 hours, a flight crew member is considered acclimatised to the new time zone when all rest periods within a 72 consecutive hour period have occurred in the same time zone; or,

• when the time zone difference between local time and last acclimatised time exceeds 4 hours, a flight crew member is considered acclimatised to the new time zone when all rest periods within a 96 consecutive hour period have occurred in the same time zone.

GYYZ-MIA – CM is acclimated, all entries remain on YYZ time.

YYZ-YVR and YYZ-YQX – CM is NOT acclimated, all entries remain on YYZ time for the 1st 72 hrs. CM becomes acclimated upon receiving all rest periods within a specific time zone in a 72 hr period.

YYZ-CDG – CM is NOT acclimated, all entries remain on YYZ time for the 1st 96 hrs. CM becomes acclimated upon receiving all rest periods within a specific time zone in a 96 hr period.

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 CM's reference time zone (RTZ).

Note:Difference between Duty Time and FDPOperational Ferry

For an CM 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: Sleep opportunity:Measured from Release to Report. Measured from Hotel Check-in to Hotel Check-out.

Rest Period and Breaks

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 60 minutes.

Rest Period and Breaks


Local night’s rest (LNR) means when the flight crew member‘s rest period fully encompasses the hours between 22:30 to 07:30 in the local time zone.

Single day free from duty (SDFD)

means a time free of all duties consisting of a single day and two local night’s rest and which may include a rest period as part of the single day free from duty.

Consecutive days free from duty

means a single day free from duty followed by a further 24 hours free from duty for each additional consecutive day.

The minimum time for a LNR is 10:00.

The minimum time for a SDFD is 34:00.

The minimum time for a rest period which includes 2 LNR is 54:00.

The minimum time for a rest period which includes 3 LNR is 78:00.

The minimum time for five consecutive days free from duty is 130:00.

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

A CM is permitted to ‘Join’ an augmented FDP after the first flight, provided that the flight time for the first flight is planned to be less than 1:45 in duration.

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 that meets the Society of Automotive Engineers’ (SAE) Aerospace Recommended Practice (ARP) 4101/3, Crew Rest Facilities, used in conjunction with ARP 4101, Flight Deck Layout and Facilities.

Class 2 rest facility

means a seat in an aircraft cabin that allows for a flat or near flat and horizontal sleeping position, which is separated from passengers at least by a curtain to provide darkness and some sound mitigation, equipped with portable oxygen and is reasonably free from disturbance by passengers or crew members;

Class 3 rest facility means a seat in an aircraft cabin or flight deck that reclines at least 40 degrees from vertical, provides leg and foot support and is not attached or joined 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 pilot, the inflight rest do not overlap.

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

Night Duty Early Duty / Late Duty

Night Duty means a FDP that starts between 13:01 – 01:59 and finishes after 02:00, in the flight crew member‘s acclimatised time.

Operating Flight

Split Duty:• Is a FDP which contains a Break of at least 60 minutes 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.• 45 minutes of the break is not applied towards the FDP extension.• 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 100 % of the break that occurs between 00:00 and 5:59• Permits extensions above the scheduled FDP limits by 50 % of the break that occurs between 06:00 and 23:59• May be applied during Short-Term re-Planning, only 50% of the break is applied towards the FDP Extension.

Examples:• Break is from 00:00to 05:45 (5:45) • The permitted extension is equal to (5:45 - 0:45) * 100% = 5:00

• Break is from 10:00 to 15:45 (5:45) • The permitted extension is equal to (5:45 - 0:45) * 50% = 2:30

• Break is from 22:15 to 04:00 (5:45)• The permitted extension is equal to (5:45 – 0:45) = 1:00 * 50% + 4:00 * 100% = 4:30

• Break is from 01:59 to 07:44 (5:45)• The permitted extension is equal to (5:45 – 0:45) = 1:00 * 50% + 4:00 * 100% = 4:30

All cumulative values are across calendar periods.

Only the portion of the Duty Time or Flight Time that falls within the calendar period specified.

Duty time is accumulated across 7, 28, and 365 calendar days periods.

Flight Time is accumulated across 28 , 90 , and 365 calendar days periods.
