Should the difference between the calendar dates from when a leg arrives minus the date when the last 24 hour rest period began exceeds 6 the crewmember is illegal.

Examples:The last 24 hour rest period began on day 2. Leg 1 ends on day 8.o 8 – 2 = 6 which is less than or equal to 6, so leg 1 is legal. o The full 24 hour rest is within the 7 day span.

Leg 2 ends on day 9.o 9 – 2 = 7 which is greater than 6, so leg 2 is illegal.o Only 20 hours of the last 24 hour rest falls within the 7 days span.

Leg 3 ends on day 9.o 9 – 2 = 7 which is greater than 6, so leg 2 is illegal.o Only 20 hours of the last 24 hour rest falls within the 7 days span.

CASR 121.472(f) – Extension Beyond Scheduled FDP limit• May only be applied for unforeseen operational circumstances on domestic operations

only.• The scheduled FDP limits may be extended by 3:00 provided that:

• The rest period following extended FDP is increased beyond the required rest by the amount of the FDP extension.

• All Flightcrew involved first consider that safety will not be an issue.


All Flight Crew Members:

CASR 121.475 – Crewmembers on ReserveEach Reserve assignment must provide time for a crewmember to have a sleep opportunity of not less than 8 consecutive hours.• The crewmember must have been notified at least 24:00 before the start of the sleep opportunity. • During the rest period the carrier may not contact the crewmember. • The rest period must occur during each 24 hour period
