Best Combined ATO/AOC Operations Software 2026: Complete Comparison

The practical consequence is a software gap. Pure flight school platforms handle ATO training records well but cannot model AOC charter billing, crew duty time aggregation across certificates, or sales-to-dispatch workflows for commercial customers. Pure charter and AOC platforms handle dispatch and crew rostering well but lack student syllabus tracking, CBTA progression, and the audit-ready training file inspectors will request during ATO oversight. Combined operators that try to use one tool for both ends up running parallel systems — and the seam between the systems is where revenue, duty time accuracy, and compliance gaps appear.

We wrote about the broader operational picture in managing combined ATO/AOC operations, and the underlying regulatory differences in EASA vs FAA compliance. This article compares the six platforms operators most commonly evaluate when they need software that genuinely covers both certificates.

Aviatize is built around the assumption that a modern operator does more than one thing. The platform combines scheduling, component-level maintenance, multi-rate billing, training records, document compliance, and safety reporting in a single system — covering the full mix of ATO, AOC, SPO, and HEMS activities under one tenant.

Multi-certificate scheduling is core to the design. Each booking carries its certificate context, which drives the validation rules, the duty time accounting, and the invoicing logic. A morning training flight under Part-FCL, a midday Part-CAT charter, and an evening Part-SPO survey all use the same scheduling engine but with different rules applied per booking. Duty time aggregates across all activities — a pilot flying training in the morning and an AOC charter in the afternoon cannot be booked into a third flight that would breach the cumulative limit, even if no single activity has exceeded its individual limit.

The billing engine uses itemised line items for both sides. Training is billed by the Hobbs hour at a fixed rate with separate aircraft, instructor, and landing-fee lines. AOC charter is billed with positioning legs, productive flight time, on-site standby, daily minimums, monthly retainers, and mission-specific fuel surcharges — all generated automatically from the booking type. The same airframe that flies a training sortie on Tuesday at the standard Hobbs rate flies a survey mission on Wednesday with positioning, productive, and four-hour daily minimum lines. Accounting integrations cover PEPPOL, Sage Intacct, Exact Online, and QuickBooks.

Aviatize supports 110+ aviation authorities natively — including EASA, UK CAA, FAA, CASA, TCCA, and others — with the validation rules adapting to each operator's regulatory mix. Crew qualifications track type ratings, instructor authorisations, examiner approvals, HEMS crew member certificates, and currency expirations across all certificates simultaneously. The native iOS and Android apps cover student check-in, instructor lesson grading, charter dispatch, squawk reporting, and document uploads. Pricing is per aircraft per month, starting at €29 per aircraft on an annual plan, with all users included.

FL3XX, founded in Vienna in 2010, is one of the most visible modern aviation management platforms for charter and business aviation. Its core strength is the sales-to-dispatch pipeline: charter quoting, contract management, dispatch, crew, flight tracking, and maintenance in a single cloud platform. FL3XX claims more than 250,000 flights dispatched annually across 60 countries, with named customers including AirSprint, Hahn Air, AirX, and Comlux.

For combined ATO/AOC operators, FL3XX appears on this list with explicit honest disclosure: it is not a flight school training platform. The product does not include student syllabus management, CBTA progression tracking, lesson grading, or stage check workflows. Combined operators that want FL3XX for the charter side typically run a separate ATO platform alongside it for the training records — and that pattern is common enough to be worth describing here. FL3XX strengths on the AOC side are real: a modern cloud-native UI, more than 180 advertised third-party integrations, and a single platform spanning sales, dispatch, crew, and maintenance.

The trade-offs for combined operations are about the seam between two systems. Crew duty time aggregated across the AOC side and a separate ATO platform requires manual reconciliation or custom integration. Aircraft maintenance status visible on both sides requires either a single shared maintenance system or a connector. Native SMS depth is limited; FL3XX integrates with Polaris Aero's VOCUS for SMS and FRAT. Pricing is not published.

Air Maestro, built by Adelaide-based Avinet since 2005, is one of the most established aviation operations platforms in the southern hemisphere. The product was born out of safety management — that lineage shows in how mature the SMS, hazard, risk-register, and fatigue modules feel compared to platforms that bolted SMS on later. It now spans more than 20 configurable modules covering crew rostering, training, fatigue, document control, and aircraft management, alongside its safety core.

For combined operators in the AU/NZ and broader Asia-Pacific market, Air Maestro is a natural fit. Avinet's customer mix — aeromedical and HEMS, charter airlines, aerial firefighting, agricultural aviation, public safety, cargo, RPAS — is exactly the population of operators that hold combined certificates and need SMS depth as a buying criterion. Avinet markets approximately 300 operators across 48+ countries. Fatigue management is a first-class module rather than a sub-feature of crew scheduling, which matters when duty patterns span training, charter, and HEMS standby.

The limitations are around maintenance depth and pricing transparency. Air Maestro markets aircraft management modules, but the depth of parts inventory, airworthiness directive tracking, and component-life management is not detailed on its public product pages — operators with heavy MRO requirements should ask for specifics during evaluation. Pricing is not published. The platform is most heavily marketed within CASA and AU-NZ regulatory framing rather than as a global multi-authority platform.

Leon Software, founded in Warsaw in 2007, is one of the longer-running European charter and business-aviation operations platforms. The product covers scheduling, sales and quoting (with built-in CRM and Avinode integration), crew management with a customisable Flight Time Limitations engine, dispatch, maintenance integration, and reporting from a single web app. Leon claims more than 200 concurrent aviation companies and over 1,000,000 flights dispatched cumulatively, with named customers including TAG Aviation, Elit'Avia, and Air Alsie.

For combined ATO/AOC operators, Leon appears on this list with the same explicit honest disclosure as FL3XX: it is not a flight school training platform. Leon's product pages do not describe any student syllabus, CBTA progression, stage check, or lesson tracking module. Operators that combine ATO training with AOC charter and want to use Leon for the AOC side run a separate ATO platform alongside it. Leon's distinctive strengths on the AOC side are the configurability of its FTL engine, native multi-AOC support in a single tenant — useful for operator groups holding several certificates — and an unusually broad public integration catalog spanning OPS, marketplaces, maintenance, and SMS partners (100+ services listed).

Leon's SMS is delivered via third-party integrations (IQSMS, ARC, q5, SAFE) rather than as a native module. Pricing is not published. The platform was recently extended with a GraphQL API and an MCP server for AI-tool access (released September 2025), which signals continuing investment in the integration surface.

ARMS — Aviation Resource Management System — is the flagship suite from Laminaar Aviation Infotech, a Singapore-headquartered company with offices in Mumbai and Bengaluru. ARMS is one of the few platforms on this list that genuinely covers both ATO and AOC sides natively, with separate sub-systems for flight operations (FOSS), maintenance and engineering (M&ESS), crew management (CMSS), safety and quality (SQMS), and integrated training management (ITMS). The product is aimed at airlines, cargo operators, MROs, and large training organisations rather than mid-size combined ATO/AOC operators.

For large combined operators — particularly in DGCA-regulated India, GCAA / GACA Middle East, and CAAS Singapore — ARMS is genuinely positioned for the segment. The single unified database across flight ops, maintenance, crew, and safety reduces inter-module sync issues compared to multi-vendor stacks. The ITMS module is well-suited to airline cadet programs and large ATO scale, the SQMS module handles FOQA / MOQA with ICAO Doc 9859 alignment, and modular deployment lets operators buy single sub-systems if they don't need the full suite.

The trade-offs reflect the enterprise positioning. ARMS is likely to carry a heavy implementation footprint and is less suited to smaller combined ATO/AOC operators with simpler requirements. Public product pages are sparse on screenshots and demo content compared to modern SaaS competitors, customer transparency is limited (few public logos or case studies), and pricing is enterprise-quote only. Founding year is inconsistent across third-party sources (1993, 2002, and 2016 cited by different directories).

FlightLogger, founded in Denmark in 2011, is one of the better-known training-focused flight school platforms internationally with a marketed footprint of 60,000+ users across 44+ countries. Its core strength is training management — syllabus management, lesson grading, evaluations, competency-based progression, and document expiry tracking are all well developed. For combined operators whose ATO side is the centre of gravity and whose AOC charter activity is secondary, FlightLogger handles the training records with multi-framework support across EASA, FAA, CASA, and ANAC.

For pure AOC charter operations, FlightLogger is not the natural fit. The platform does not include charter sales workflows, multi-rate billing for positioning and standby, or the dispatch depth that AOC operators typically need. Combined operators that want FlightLogger for the training side typically run a charter platform alongside it — FL3XX, Leon Software, or another AOC-focused tool — for the commercial side. This pattern is the mirror image of the FL3XX-and-separate-ATO pattern: you get strong training records on one side, strong charter ops on the other, and a manual seam between them.

The limitations on the training side are familiar to anyone who has evaluated FlightLogger: per-active-student pricing that scales with enrolment, limited billing flexibility without itemised line items, maintenance that lacks parts inventory and AD tracking, and an SMS module that is a paid add-on rather than included.

Aviatize is the exception with published per-aircraft pricing from €29 per aircraft per month on annual billing, with all users included. For a combined operator running 12 aircraft across both sides of the operation, software cost stays constant regardless of how many students, instructors, dispatchers, charter clients, or admins use the system.

When comparing custom quotes, look beyond the headline rate at what is included versus paid as add-on. SMS modules, training modules, integration fees, hardware costs, onboarding fees, and support tier pricing all add to the total. A combined operator running two single-purpose platforms — one for ATO and one for AOC — should also factor in the integration cost between systems and the manual reconciliation effort for crew duty time and maintenance status.

Start with your activity balance. If your operation is 80% training and 20% charter, FlightLogger paired with a smaller AOC platform may work well — your centre of gravity is the training records. If your operation is 80% charter and 20% training, FL3XX or Leon Software paired with a smaller ATO platform is a sensible pattern. If your operation is genuinely balanced — significant volume on both sides — the cost of two systems plus the seam between them adds up, and a platform built for both certificates in one tenant becomes more attractive.

Consider your authority and regulatory mix. Operators in AU/NZ with HEMS and aerial-work activities lean toward Air Maestro. Operators in DGCA-regulated India, GCAA Middle East, or CAAS Singapore at airline scale lean toward ARMS. European combined operators looking for a single multi-authority platform across EASA, UK CAA, and other frameworks lean toward Aviatize.

Pressure-test the duty time and billing seams. The two places combined operations bleed accuracy and revenue are crew duty time aggregation across certificates and itemised charter billing for positioning, standby, and minimums. If you are evaluating two platforms instead of one, walk through a realistic week — pilot flying training Monday through Wednesday and Part-CAT charter Thursday through Friday — and check whether the duty time totals at the end of the week match what your authority would expect to see during oversight.

Test data portability. Combined operations accumulate two streams of regulated records — training files and AOC records — both of which may be required during oversight. Ask each vendor what export formats are supported and how long records are retained. Comprehensive CSV export plus a documented REST API is the standard worth holding vendors to.

For operators that genuinely want one platform across both certificates — with itemised multi-rate billing, crew duty aggregation, multi-authority validation, and per-aircraft pricing that does not punish growth on either side — Aviatize is built for that scenario. For combined operators with strong existing investments on either the AOC side (FL3XX, Leon) or the ATO side (FlightLogger), the two-platform pattern works as long as the seam between systems is managed deliberately.
