Pilot rosters explained: ON days, OFF days and why schedules vary

Why there is no universal five-on, four-off rule

A repeating sequence such as five days on and four days off is easy to understand in a simulation, but it is not a rule shared by every airline. Some operations publish monthly schedules, some use bidding, and others combine fixed patterns with reserve or variable flying. Even people working for one airline can have different arrangements.

For a realistic career simulation, a roster should be associated with an operator model and a contract rather than presented as an unconditional promise about real-world working conditions.

The parts of a useful roster

• Duty: the period in which the crew member is required to work or report for an assignment.
• Flight sector: one planned flight within a duty, potentially followed by another sector.
• Standby or reserve: a period when the crew member must be available for assignment, subject to the applicable rules.
• Rest: time allocated for recovery and away from duty; it is not necessarily interchangeable with a day marked OFF.
• Base: the usual reporting location; working away from base can change how a sequence is constructed.

How to read a pattern

Start with the published roster period. Identify the days with assigned duties, the days reserved for standby, and the periods shown as rest. Then review the time between the end of one duty and the next report, not just the number of calendar squares marked OFF.

A simulator that shows a five-on/four-off example should label it as an operator-specific or representative model. A variable schedule should not be silently reduced to a fixed cycle just because fixed cycles are simpler to generate.

What PilotShift can model responsibly

PilotShift can make the experience believable by showing the roster model, the selected base and the employment context. Where a real schedule is not publicly verifiable, a clearly labelled simulation model is preferable to pretending that an invented cycle is a confirmed company policy.

If you find a reliable, publicly accessible source about a roster arrangement, the Operations Center can collect a proposal for staff review. An editorially accepted proposal is not the same as a live change to an existing player roster.

Before your next duty

• Check your report time, destination, aircraft and available qualifications.
• Review any standby periods and the time available between consecutive duties.
• Treat simulated patterns as game rules unless the article explicitly identifies a verified external source.
