Below you find the article as published in the current CWA. Further below we provide some comments and explanations for this article.
Like always it is the obligation of the company to follow these rules and a pilot is entitled to a roster reflecting these rules. If a pilot notices a non-compliance with the CWA it is his/her right that his roster will be changed to be fully compliant with the CWA.

36.10.4 Recurrent Extended Recovery Rest Periods The minimum Recurrent Extended Recovery Rest Period shall be 36 hours, including 2 Local Nights, and in any case the time between the end of one Recurrent Extended Recovery Rest Period and the start of the next Extended Recovery Rest Period shall not be more than 168 hours.
The Recurrent Extended Recovery Rest Period shall be increased to 2 Local Days twice every month.
Recurrent Extended Recovery Rest Periods may be scheduled concurrently with rest requirements for time zone difference compensation.
Recurrent Extended Recovery Rest Periods shall be planned and crew members notified sufficiently in advance.

This article states that the minimum recurrent recovery rest period must be a minimum of 36 hours, including 2 local nights. Furthermore, not more than 168 hours shall be between the end of one recurrent extended recovery rest period and the start of the next one.
Additionally, the recurrent extended recovery rest period must be increased to 2 local days twice every month and may be scheduled concurrently with rest requirements for time zone compensation.
Note: Recurrent Extended Recovery Rest Periods are also a limitation in the OM-A and limits must not be exceeded in any case!
Example:
A pilot is scheduled for a trip, which departs LUX on day 1 at 11:00 UTC and is supposed to come back on day 7 at 04:00 UTC. Time between reporting for duty at 10:00 UTC on day 1 and going off duty on day 7 at 04:30 UTC is 162:30 hours. During this rotation, the longest scheduled rest period is 32 hours. Due to delays and changes, the pilot departs late from CGO to OVB and is planned to continue to LUX on the same flight. ETA in LUX would be 12:00 UTC on day 7, resulting in more than 168 hours since the end of his last extended recovery rest period. As per CWA and the OM-A, the pilot must take a rest period in OVB and is not allowed to continue to LUX. Because he had a disruptive schedule with 4 night duties, early starts and late finishes, based on the reference time the pilot was acclimatized to, the rest period in OVB must be increased from the minimum of 36 hours and 2 local nights to 60 hours minimum.
Please note, the intention of any rest period is to enable a pilot to be rested for the next duty or series of duties and to stay sufficiently free from any fatigue!
If pilots feel that they are not sufficiently rested before the next duties then they should extend their rest and complete a proactive fatigue report.

36.10.5 Increased rest requirements due to Disruptive Schedules For a Pilot performing 4 or more Night Duties, Early Starts or Late Finishes between 2 Extended Recovery Rest Periods, the second Extended Recovery Rest Period is extended to 60 hours. Such a Recurrent Extended Recovery Rest Period may be scheduled concurrently to other rest requirements including but not limited to rest required for time zone difference compensation.
When a transition at Home Base is planned from a late Finish/Night Duty to an Early Start, the Rest Period between the 2 Flight Duty Periods includes 1 Local Night. |
Disruptive Schedule is defined in OM-A Chapter 7, Section 2 as “Means a crew member´s roster which disrupts the sleep opportunity during the optimal sleep time window by comprising an FDP or a combination of FDPs which encroach, start or finish during any portion of the day or night where a crew member is acclimatised. A schedule may be disruptive due to early starts, late finishes or night duties.”
Additional increased rest is required if a pilot performs 4 or more Night Duties, Early Starts or Late Finishes based on his status of acclimatization between 2 extended recovery rest periods. In such a case the second extended recovery rest period must be a minimum of 60 hours.
In this context the OM-A defines
· Early Start as “a duty period starting in the period between 05:00 and 05:59 in the time zone to which a crew member is acclimatised;”
· Late Finish as “a duty period finishing in the period between 23:00 and 01:59 in the time zone to which a crew member is acclimatised;”
· Night Duty as “duty period encroaching any portion of the period between 02:00 and 04:59 in the time zone to which a crew member is acclimatised.”
Important to know: The reference for determining an Early Start, Late Finish or Night Duty is the reference time a pilot is acclimatized to according to CWA 36.6.2.1.
Please note, the intention of any rest period is to enable a pilot to be rested for the next duty or series of duties and to stay sufficiently free from any fatigue!
If pilots feel that they are not sufficiently rested before the next duties then they should extend their rest and complete a proactive fatigue report.
