Calculation (if applicable) |
|---|---|---|
| Tour of duty | One or more work assignments defined by the time between the first embarkation to the last disembarkation. | Tours were delineated according to breaks between assignments: when there were 7 or more days break between consecutive work assignments it was determined that a new tour had commenced; 3 or fewer days break between work assignments were considered to represent a continuation of a tour; 3-7 day breaks were individually assessed. |
| Tour duration | Length of tour of duty. | Defined by the time between the first embarkation to the last disembarkation (based on the definition of a tour). |
| Tour breaks | Length of time between tours of duty. | Calculated from the last disembarkation of one tour to the first embarkation of the next (based on the definition of a tour). |
| Work assignment | A continuous period of time when a pilot is on board ship. | |
| Work assignment duration | Number of hours spent on the ship. | Measured from embarkation to disembarkation and adjusted for travel to and from the ship. |
| Breaks between assignments | Non-ship time. | Calculated from disembarkation to embarkation. |
| Day and Night Time Periods | Day time period extended from 0525 and 1818. | Based on the civil twilight hours averaged across 12 months and three areas in the Great Barrier Reef region. |
| Night hours for assignment | Period of time between 1818 and 0525 spent on ship. | Based on the definitions of night time periods and work assignments. |
| Travel to and from a tour | Hours of travel from home to the port location of the first work assignment of a tour and from the disembarkation point of the final work assignment of a tour to home. | Calculated from information regarding the location of the pilot’s home residence and airline schedules. This time was not regarded as work. |
| Travel between ports | Hours of travel from one port ashore to the next port. | Calculated from airline schedules regarding the duration of flight times between ports. Determined as work time in the analysis. |
| Travel to and from work assignments | Travel from port to boarding ground to meet ship and from boarding ground back to port. | Calculated from information supplied by pilotage companies regarding travel duration to and from boarding grounds. Mode of travel was not considered. |
