Crew bidding, duty/rest, and qualifications that scale with the fleet.
Part 121 means thousands of pilots, hundreds of training events a week, and a duty/rest regime that has to hold up under inspection. Run the crew side as one system of record — bidding, reserve, open-time, MEL, and FAR 117 — without losing the audit trail.

Today
What's slowing you down
- Bidding run in a legacy PBS tool whose UI predates the smartphone
- Reserve and open-time tracked in a spreadsheet the crew desk rebuilds nightly
- FAR 117 legality checked by hand, after the line is already built
With AviationAlley
What changes
- One workspace for bidding, reserve, open-time, and MEL
- FAR 117 duty/rest checked before a pairing posts
- Award runs are idempotent — the same inputs always produce the same lines
Every part, broken down
What you get for 14 CFR Part 121
Pilot bidding (LINE + PBS)
Seniority-ordered, deterministic, idempotent awards.
Per base × equipment × position, DRAFT → OPEN → CLOSED → AWARDED → PUBLISHED.
Hard rules filter, soft rules score, lowest line number breaks ties.
A pure awards function — re-running replaces prior awards with the same result.
Per-line pairing CRUD inside each package, with a reserve-pool fallback.
Duty, rest & fatigue
Deterministic FDP/rest checks at assignment time — violations blocked before they post.
Parallel duty/rest engine for flight attendants.
Live FDP-used per crew member, derived from shifts and the flight log.
Deterministic and explainable — blends FAR 117 load with self-reported sleep signals. Not an AI prediction model.
Reserve, open-time & MEL
LONG_CALL + SHORT_CALL with callout and no-contact tracking.
Drop / pickup / swap with planner approval; auto-approve when no FAR 117 bust.
Category A/B/C/D auto-rolling expiry; expired items ground the aircraft.
Qualifications & recurrent
Per-fleet proficiency objectives and CQ-cycle enrollments.
121.421 initial / recurrent / transition / overwater on a 12-month cycle.
Four-month grid across credentials, FA recurrent, and inspections.
Random-selection records with a full audit trail.
In every operation
The platform-wide backbone — the same under every FAR Part.
Auto-fills from completed flights, manual entry, and ForeFlight CSV import/export.
Certificates, ratings, medicals, and type ratings with auto-expiry alerts and document storage.
Priority/status/assignee work orders, parts with reorder thresholds, vendors, and purchase orders.
Every requirement on a Compliant → Due-Soon → Overdue timeline with a weekly admin digest.
Utilization, currency, and activity KPIs with CSV export.
Every mutation recorded with actor, entity, and timestamp — searchable and exportable.
Read-only links for FAA/POI/external auditors that expire automatically — no shared logins.
Bearer-token REST API (scoped) and HMAC-signed outbound webhooks for HRIS, ERP, and ops integrations.
Tenant isolation, role-based access, per-employee surface restrictions, TOTP 2FA, and GDPR data export/erasure.
Why operators switch
What we have. What incumbents don't.
| AviationAlley | Status quo |
|---|---|
| Modern PBS UI built this decade | AD OPT / Sabre CrewTrac UIs date to the 90s |
| LINE and rule-based PBS modes | Many regional incumbents force LINE-only |
| Public REST API + signed webhooks | Bespoke integrations, multi-month engagements |
| Modular by FAR — pay for what you use | Monolithic suites; pay for unused modules |
