It is possible during other-standby to assign a duty that will start after the rostered end of the standby period.
Duties assigned during other-standby should in principle start within the operator’s defined response time from the call. For example, a cabin crew while on home standby between 08:00h and 14:00h (as planned in the roster) receives a call at 13:55 h to report for duty at 14:55 h since the operator’s response time is 60 min. The response time between the call and reporting is considered a continuation of the standby, notwithstanding the rostered end of the standby; this time also includes travelling to the reporting point.
Operators describe their procedures and practices regarding standby, including reporting after the rostered standby period ends, in the OM-A. In doing so, they take into account that the Regulation provides a number of cumulative protections to crew member from excessive periods of combined standby and duty:
- Operators shall only use the rostered standby availability period to place their call for duty. ORO.FTL.105 (25) defines standby as the period of time during which a crew member is required by the operator to be available to receive an assignment for a flight;
- The maximum duration of other-standby is 16 hours. In its OM-A however, the operator may specify shorter periods considering its type of operation and the impact of the time spent on standby on the duty that may be assigned. Under the obligations of ORO.FTL.110 (b & e), operators must carefully evaluate what duration of standby is safely allowable within their particular operation;
- The combination of standby and FDP do not lead to more than 18 hours awake time (see FAQ # 60);
- The maximum FDP is reduced, if the standby period ceases after the first 6 hours (or 8 hours in case of extended FDP);
- A crew member is always able to consider whether his/her duties on board an aircraft will be performed with the necessary level of alertness (CAT.GEN.MPA.100(c))
If no duty has been assigned during the rostered standby availability period, other-standby is followed by a rest period in accordance with ORO.FTL.235.
