Part 121 · Network-aware scheduling
Explainable swap / re-base suggestions
When an aircraft swap or a re-base would lower the efficiency score without creating a maintenance-routing risk, the board proposes it and shows the reasoning behind it — what it changes and how many points it saves. The suggestions are deterministic and explainable heuristics: the same inputs always produce the same proposals, and each one traces back to its inputs. They are not AI, not a solver, and not a claim of the single optimal schedule — they are ranked, transparent improvements you choose to apply. It replaces rebuilding pairings by hand just to test whether a change helps.

Who it's for
Crew planners at a Part 121 operation who, once this ships, want ranked swap and re-base proposals with their reasoning shown, rather than rebuilding pairings by hand to test whether a change helps.
What it replaces
Rebuilding pairings by hand just to test whether a change helps.
What explainable swap / re-base suggestions gives you
- In development — will propose swaps and re-bases that lower the score
- Every suggestion shows its reasoning and traces to its inputs
- Deterministic, not AI and not a guaranteed optimum
Proposals that show their reasoning
This capability is in development. Once it ships, when an aircraft swap or a re-base would lower the efficiency score without creating a maintenance-routing risk, the board will propose it and show the reasoning behind it — what it changes and how many points it saves. A planner will choose whether to apply each ranked, transparent improvement; it is not yet in production.

Deterministic, not AI and not a guaranteed optimum
As planned, the suggestions will be deterministic, explainable heuristics: the same inputs will always produce the same proposals, and each will trace back to its inputs. They will not be AI, not a solver, and not a claim of the single optimal schedule — they will be ranked, transparent improvements a planner chooses to apply. It is in development, not yet in production.

How an operator uses this
This capability is in development. Once it ships, when an aircraft swap or a re-base would lower the efficiency score without creating a maintenance-routing risk, the board will propose it and show the reasoning behind it — what it changes and how many points it saves. The suggestions are designed as deterministic, explainable heuristics: the same inputs will always produce the same proposals, and each one will trace back to its inputs. They will not be AI, not a solver, and not a claim of the single optimal schedule — they will be ranked, transparent improvements a planner chooses to apply. It is not yet in production.

How it works
Explainable swap / re-base suggestions, step by step
Planned: when a swap or re-base would lower the score without a routing risk, the board will propose it.
Planned: each suggestion will show its reasoning — what it changes and how many points it saves.
Planned: the same inputs will always produce the same proposals, each tracing to its inputs.
Planned: a planner will choose whether to apply each ranked, transparent improvement.
Questions
Explainable swap / re-base suggestions — frequently asked
Are the swap / re-base suggestions AI?
No. They are planned as deterministic, explainable heuristics — the same inputs will always produce the same proposals, and each will trace back to its inputs. They will not be AI, not a solver, and not a claim of the single optimal schedule. This capability is in development.
Will the board apply a swap automatically?
No. The suggestions are planned to be ranked, transparent improvements a planner chooses to apply — each shows its reasoning first. The feature is in development, not yet in production.

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 diveEvery Part 121 workspace also includes the platform-wide backbone — logbook, credentials, compliance, reporting, and audit trail.
