Part 121 · Reliability & reporting
Fleet utilization
Per-tail hours over 30 / 90 / 365 days sit next to an inspection countdown, so planners see which aircraft is overworked and which inspection is closest. It replaces the utilization tally done by hand each month.
Launching the first quarter of 2027.
Illustrative — every screen reflects your own data.
What fleet utilization gives you
- Per-tail hours over 30 / 90 / 365 days
- An inspection countdown alongside
- Which aircraft is overworked and which inspection is closest
How an operator uses this
Each tail gets a 0–100 aircraft-on-ground risk score that surfaces which aircraft to look at first, shown with the factors that drove it — airworthiness posture, inspection timing, utilization, and age — so it's deterministic and explainable, not a black-box prediction. Per-tail hours over 30 / 90 / 365 days sit next to an inspection countdown, so planners see which aircraft is overworked and which inspection is closest. Managers get a morning email of today's operation and the items needing attention, and every utilization, currency, and completion KPI rolls up across the operation and exports to CSV for a board pack — replacing the month-end rebuild across disconnected tools.
Illustrative — every screen reflects what's in your own data, nothing more.

Deep diveCrew duty board
Live duty used per crew member, derived from shifts and the flight log.
Deep diveFatigue risk board
Deterministic and explainable — blends documented duty load with self-reported sleep signals. Not an AI prediction model.

Deep diveManager daily digest
Today's ops and attention items emailed to managers each morning.
Deep diveReports & exports
Utilization, currency, and completion KPIs with CSV export.
Deep divePilot dashboard
A pilot's own home: next flights + FAR 117 duty standing, report-for-duty check-in, PBS bid status, 61.51 logbook, currency and credentials.
Deep diveFlight-attendant dashboard
Trips and schedule, 14 CFR 121.421 recurrent-training status, credentials, check-in, manuals, and fatigue reporting.
Deep diveCrew planner & dispatch
Bid packages and awards, reserve and open-time, and the live ops / dispatch board for the people running the operation.
Deep diveManager & compliance
Fleet, recurrency, FAR 117 oversight, and audit-ready compliance — role-scoped, one Part at a time.
Deep diveMaintenance-station routing
Flags when a tail's due check won't reach a capable station before its limit. Advisory — it surfaces the risk, it doesn't block dispatch.
Deep diveCrew-base efficiency
Surfaces deadhead and out-of-base overnights so pairings can be built to originate and terminate at a crew member's base.
Deep diveWeighted efficiency score
A configurable weighted score (abstract points, lower = better) over deadhead, overnights, repositioning, and maintenance-fit slack — set your own weights.
Deep diveExplainable swap / re-base suggestions
Deterministic aircraft-swap and re-base proposals that improve the score — every suggestion shows its reasoning. Not AI, not a guaranteed optimum.
