Part 121 · Qualifications & recurrent
Recurrent calendar
A four-month grid lays credentials, FA recurrent training, and aircraft inspections on one calendar, so training and maintenance planning see the same upcoming wall of due dates. It replaces three separate calendars that never line up.
Launching the first quarter of 2027.
Illustrative — every screen reflects your own data.
Who it's for
Training and maintenance planners who need credentialing, cabin-crew, and fleet due dates on one horizon so a heavy week is visible before it's a crunch.
What it replaces
Three separate calendars for credentials, FA recurrent, and inspections that never line up.
What recurrent calendar gives you
- Four-month grid on one calendar
- Credentials, FA recurrent training, and aircraft inspections together
- Training and maintenance planning see the same due dates
One four-month grid
A four-month grid lays credentials, FA recurrent training, and aircraft inspections on one calendar, so training and maintenance planning look at the same upcoming wall of due dates instead of three calendars that never quite line up. It's the planning horizon for the whole operation on a single grid.
- Four-month grid on one calendar
- Credentials, FA recurrent training, and aircraft inspections together
- The planning horizon for the whole operation
See a heavy week before it's a crunch
Because the credentialing, cabin-crew, and fleet due dates share one view, a week that's heavy on both recurrent training and inspections is visible before it's a crunch. Training and maintenance plan against the same wall of due dates.

Questions
Recurrent calendar — frequently asked
What does the recurrent calendar show?
A four-month grid with credentials, FA recurrent training, and aircraft inspections on one calendar, so training and maintenance planning see the same upcoming wall of due dates.
Does it combine training and maintenance due dates?
Yes. Credentialing, cabin-crew recurrent, and fleet inspection dates share one grid, so they no longer live on three separate calendars that never line up.

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.
