The eight elements your roster policy must specify.

The article, verbatim

(a) An air traffic control service provider shall develop, implement and monitor a rostering system in order to manage the risks of occupational fatigue of air traffic controllers through a safe alternation of duty and rest periods. Within the rostering system, the air traffic control service provider shall specify the following elements:

1. maximum consecutive working days with duty;
2. maximum hours per duty period;
3. maximum time providing air traffic control service without breaks;
4. the ratio of duty periods to breaks when providing air traffic control service;
5. minimum rest periods;
6. maximum consecutive duty periods encroaching the night time, if applicable, depending upon the operating hours of the air traffic control unit concerned;
7. minimum rest period after a duty period encroaching the night time;
8. minimum number of rest periods within a roster cycle.

(b) An air traffic control services provider shall consult those air traffic controllers who will be subject to the rostering system, or, as applicable, their representatives, during its development and its application, to identify and mitigate risks concerning fatigue which could be due to the rostering system itself.

• Element 1

  Maximum consecutive working days with duty

  Count consecutive duty days per controller and stop assignment once the configured maximum is reached.

  • Consecutive roster-day limitStrategichard or soft
  • Consecutive working days after a swapSwaphard

  Configurable Strategic rostering →

• Element 2

  Maximum hours per duty period

  Bound the length of a single duty period from sign-on to sign-off.

  • Daily worked-hour limitStrategichard or soft
  • Daily hours within a single shiftStrategichard or soft

  Configurable Strategic rostering →

• Element 3

  Maximum time providing ATC service without breaks

  Track continuous time on an operational position and force a break once the configured ceiling is reached.

  • Maximum continuous time on positionTacticalhard or soft

  Configurable Sector planning →

• Element 4

  Ratio of duty periods to breaks

  Hold a set proportion of break time to working time across a duty period, a ratio, not one fixed break.

  The catalogue does not contain a dedicated duty-to-break ratio rule. Related time-on-position limits do not by themselves establish that a specified ratio is enforced. Review this requirement and any necessary implementation work directly.

  Configurable Sector planning →

• Element 5

  Minimum rest periods

  Check the configured minimum gap between the end of one duty and the start of the next.

  • Minimum rest between dutiesStrategichard or soft
  • Minimum rest before position allocationTacticalhard or soft
  • Minimum rest after a swapSwaphard

  Configurable Shift swaps →

• Element 6

  Maximum consecutive duty periods encroaching the night time

  Count consecutive duty periods that fall inside the defined night-time window and cap the run.

  • Consecutive night-duty limitStrategichard or soft
  • Night-duty limit within a periodStrategichard or soft

  Configurable Strategic rostering →

• Element 7

  Minimum rest period after a duty period encroaching the night time

  Apply a longer minimum rest specifically after a duty that touched night time, distinct from the general inter-duty rest.

  • Rest after consecutive dutiesStrategichard or soft
  • Rest after accumulated working hoursStrategichard or soft

  Night-work treatment depends on configuration of the relevant rest rules. Confirm the required night window and post-duty rest behaviour during evaluation.

• Element 8

  Minimum number of rest periods within a roster cycle

  Check the configured minimum number of rest periods across the roster cycle.

  • Minimum duration of off-duty periodsStrategichard or soft
  • Minimum consecutive days offStrategichard or soft
