It states:
Say like most companies you are given a monthly schedule in which there are reserve days from xx:xx until xx:xx, let's say for arguments sake 4AM until 2PM.720.21 Flight Crew Members on Reserve
The standards for compliance with this section are:
(1) An air operator shall provide each flight crew member with an opportunity to obtain at least 8 consecutive hours sleep in any 24 consecutive hours while on reserve by one of the following methods:
(a) the air operator shall provide the flight crew member with 24 hours notice of the time of commencement and duration of the rest period. The designated rest period cannot shift more than 3 hours earlier or later than the preceding rest period, nor more than a total of 8 hours in any 7 consecutive days;
(b) the flight crew member shall be given a minimum of 10 hours notice of the assignment and shall not be assigned any duty for these 10 hours; or
(c) the air operator shall not assign the flight crew member to flight duty time and shall not interrupt the flight crew member's rest period between 22:00 and 06:00 local time.
(2) Where an air operator is unable to provide a flight crew member with a rest period required by subsection (1) and the flight crew member is notified to report for flight duty or the reporting time occurs between 22:00 and 06:00 local time:
(a) the maximum flight duty time shall be 10 consecutive hours; and
(b) the subsequent minimum rest period shall be increased by at least one-half the length of the preceding flight duty time.
Since you would be given a monthly schedule, lets disregard paragraph 1b for the sake of the interpretation of this RESERVE standard. As usually you shouldn't need to be given 10 hours prior notice of a reserve assignment unless you ran into some duty time issues on one of your flights in that month.
So therefore with respect to paragraph 1a, 1c and 2a would the correct interpretation be that for companies that issue a monthly schedule with reserve times, they aren't technically giving you a notice of "REST PERIOD COMMENCEMENT", hence the air operator can't contact you until 6AM even though your reserve schedule begins at 4AM; unless they restrict you to 10 hours duty time?
The reason I ask this is because if an air operator says you're on reserve from 4AM to 2PM, no where in the CAR's can I find that this subconciously means that your rest period is to COMMENCE at 8PM (8 hours prior to your reserve schedule). So wouldn't it mean that by giving you a reserve schedule that starts 2 hours prior to 6AM, the air operator potentially runs the risk of being able to only duty you for 10 hours if called in between 4 AM and 6 AM?
Likewise, is there anywhere in the CAR's that protects pilots being on reserve say from 4AM until 2PM, that if they are called in at 159PM for a flight assignment, they are only restricted to x amount of duty hours? It seems kind of bizarre that you would be on reserve from 4AM until 2PM, and then be expected to show up for a 14 hour duty day. I thought I read a CAR somewhere about this in that if called in during your reserve schedule, you are restricted to 14 hours of total duty time from the time of reserve commencement. Hence if your reserve started at 4AM, you are good to fly until 6PM... but I can't seem to dig it up... maybe it was in my dreams lol
I'm interested to hear your thoughts on these couple of interpretations/questions!
Thanks in advance, hope to generate some good discussion.
