FIFO Roster and Charter Schedule Planning

The only date and time that genuinely matters in FIFO scheduling is when the crew must be usable on site, pre-start, induction, or the first shift of the swing. Everything else works backwards from that: ground transfer time from the aerodrome, arrival buffer, sector length, check-in and screening at the origin, and the departure slot that makes it all fit.

Working forwards from a convenient departure time is how programs end up delivering crews mid-morning on a day shift, paying for accommodation the night before, or running two aircraft where one properly timed rotation would have done.

• On-site usable time, the fixed anchor
• Ground transfer and site induction time at the far end
• Sector length plus a realistic arrival buffer
• Check-in, screening and manifest close at the origin
• Resulting departure window, then aircraft and operator suitability

Australian resource rosters cluster around recognisable patterns, even-time arrangements such as two-and-two, longer swings such as eight-and-six or fourteen-and-fourteen, and compressed patterns for specialist or shutdown work. Each produces a different flight frequency and a different concentration of demand on particular days.

The scheduling consequence is that swing-change days carry double load: one crew out, one crew in. A well-designed program uses that, running back-to-back rotations so the aircraft carries the outbound crew home on the return leg instead of flying empty. That single decision often changes cost per seat more than any rate negotiation.

• Even-time patterns produce steady, predictable weekly frequency
• Longer swings concentrate demand onto fewer, larger movements
• Swing-change days should be flown as back-to-back rotations
• Compressed and specialist rosters usually need ad-hoc capacity alongside the program

Flight crew duty limits are regulatory, not commercial. An early departure and a late return on the same day may exceed what one crew can legally operate, which means either a second crew, a crew overnight at one end, or a schedule adjustment. Knowing this early avoids a program being priced on a schedule that cannot be flown.

Airport curfews and operating hours matter at both ends. Perth is curfew-free, which is a genuine advantage for pre-dawn departures; several east coast and regional airports are not, and some remote strips are daylight-only or have no lighting at all, which puts a hard boundary on arrival and departure times.

• Flight and duty time limits, including standby and overnight requirements
• Origin and destination curfews and published operating hours
• Daylight-only strips and lighting availability at remote aerodromes
• Ground handling and screening availability at the hours you need
• Wet-season and weather serviceability in northern regions

Shutdowns, turnarounds and major project phases pull hundreds of extra people into a region inside narrow windows, and that demand lands on the same routes at the same hours as everyone else's. A program schedule that is comfortable in steady state can be genuinely tight during peak season.

The practical approach is to protect the base pattern with contracted capacity and layer additional rotations over it for the peak, rather than trying to squeeze surge demand into the existing schedule. Share peak dates as early as they are known, availability during shutdown season is a real constraint, not a negotiating position.

Schedules survive contact with reality through manifest discipline. A clear manifest deadline, a single nominated site contact per rotation, and an agreed process for late changes and no-shows keep the aircraft departing on time with the right people aboard.

When something moves, weather, serviceability, a failed fitness-for-work check, a delayed contractor mobilisation, the important thing is a named charter manager with authority to re-plan, on a desk staffed 24 hours. Programs do not fail because disruptions happen; they fail because nobody is accountable when they do.

• Agreed manifest format, deadline and change process
• One nominated site contact per rotation
• Documented no-show and late-arrival handling
• Named charter manager and 24/7 escalation path
• Periodic review of on-time performance against shift-change windows
