* Above limits may be exceeded for ferry purposes at Pilot In Command (PIC) discretion.
** Night operations are those when the flight lands after midnight or the staff show time for work is 5 AM or earlier, local time.
*** No reporting for duty; may not occur on a hard down day; no flight planning for the pilots may occur on the changeover day.
The PIC will always have the option of calling a no-flight day when consecutive flights are scheduled and crew fatigue is a factor.
The crew duty limits apply to flight crew and all RAF staff in the field. Exceptions to non-flight critical duty limits may be allowed by field project managers on a case by case basis and must be reported to RAF Manager.
