Part 135 duty trackingwithout the spreadsheet.
Duty and rest under FAR 135.267, checked continuously and enforced at dispatch — for every pilot, on every trip, with the history kept.
The duty day, drawn to scale.
These are the defaults. Each value is set per operation, so the rules in the software are the rules in your ops specs — and when a pilot would bust one, the release button does not unlock.
- Daily duty
- 14 hours
- Single-pilot flight
- 8 hours
- Dual-pilot flight
- 10 hours
- Minimum rest
- 10 hours between duty periods
- Rolling 24-hour
- 8 hours of flight time
- Rolling 7-day
- 34 hours of flight time
- Calendar quarter
- 500 hours
- Calendar year
- 1,400 hours
- Duty padding
- 30 min before / 30 min after
Checked where the decisions happen.
- On the calendar — duty alongside trips, crew availability, and aircraft blocks
- At quoting — the Smart Scheduler ranks legal crew options with the margin shown
- At dispatch — warnings and hard blocks before the release unlocks
- In the cockpit — today's duty and time remaining on the offline iOS app
- Afterward — duty rolls kept with the trips that generated them, exportable
Which limits does Contrails track?
The FAR 135.267 set: the daily duty window, single-pilot and dual-pilot flight-time limits, minimum rest between duty periods, and rolling 24-hour, 7-day, calendar-quarter, and calendar-year flight-time totals. Every value is configurable so the software matches your ops specs.
Does on-call time count as duty?
It can — that is a configuration choice per operation, because ops specs and legal interpretations differ. Contrails supports counting on-call status as duty, and applies automatic duty padding before and after flights.
What happens when a pilot is near a limit?
Warnings surface on the schedule, and hard blocks fire at dispatch: a release does not unlock against a crew member who would bust duty, rest, or a rolling total. The Smart Scheduler shows the margin on every legal option, so the person quoting a pop-up trip sees the tightest number before committing.
Can pilots see their own duty state?
Yes. The iOS app shows today's duty, time remaining, and month totals — offline, so it works mid-leg with the LTE off. Duty hours can also push to a pilot's personal calendar.
Is the duty log audit-ready?
Duty rolls are kept on the same record as the trips that generated them and are exportable. Releases store the duty check that was run at dispatch time, as it was at that moment.
