Complete Documentation Management for Airlines
CustoTool gives airlines complete control over flight operations documentation from multiple OEMs. Built natively on ATA 2300, it handles everything from receiving OEM updates through customization to preparing content for crew delivery.
Airlines face unique complexity : fleet-specific customizations, company procedures and restrictions, multi-aircraft type operations, and the challenge of maintaining changes through OEM updates. CustoTool is built to handle this complexity without compromising data quality or integrity.
Multi-OEM Content Management
Handle documentation from any manufacturer in one truly unified system. CustoTool’s ATA 2300 foundation eliminates OEM data silos—no parallel workflows, no format-specific expertise required. Supports all aircraft types: fixed wing, rotary, commercial, military, business aviation.
Our converters provide format flexibility on import and export, transforming manufacturer-specific formats into standardized ATA 2300 data. As more OEMs adopt ATA 2300 natively, your system is ready—no migration required. One standard, one skillset, your entire fleet.
Intelligent Revision Management
Streamline the revision cycle with our proprietary 3-way merge technology. When OEM updates arrive, the system intelligently compares changes with your airline customizations, highlighting conflicts for your review rather than requiring manual comparison.
What used to take days of manual cross-checking now takes minutes with guided review workflows.
Configuration-Specific Content Management
Manage aircraft-specific content with precision. Define applicability parameters for your fleet—aircraft serial numbers, configuration, and other criteria that determine which content applies to which aircraft.
For each data module, create configuration-specific versions and assign them to the appropriate applicability parameters. When you export or deliver content, intelligent filtering ensures each aircraft receives exactly the right information—no manual assembly, no risk of crews seeing irrelevant procedures or incorrect data.
Handle complex applicability across your fleet while maintaining complete data integrity.
Customization and Approval Workflows
Add airline-specific procedures, notes, and modifications with full version control. Built-in approval workflows ensure changes are reviewed and authorized before reaching flight crews.
Quality features:
• Full revision history and audit trails
• Version control across fleet
• Audit-ready documentation
• Traceability from OEM source through your customizations
Flexible Output Preparation
Export documentation in ATA 2300 or converted formats to crew delivery applications such as a tablet viewer. The structured data ensures your content works with current and future delivery systems.
Prepare content for integration with third-party viewer applications while maintaining complete data integrity.
Compliance Tracking
Import regulatory or other policy items and track compliance of your content against them. Compliance tracking allows users to review the impact of policy changes on specific data modules.
Generate compliance reports and be ready for audits.

OEM Solutions
OBE ProdTool
Efficient Authoring for OEMs
ProdTool enables OEMs to create ATA 2300-native flight ops documentation efficiently. Authors work in intuitive interfaces while the system manages XML complexity behind the scenes, ensuring content is structured correctly and ready for direct delivery to airline systems.
OEMs must manage multiple aircraft configurations, integrate supplier-provided content, ensure regulatory compliance across jurisdictions, and handle frequent updates and revisions. ProdTool streamlines content operations while maintaining rigorous quality standards.
Intelligent Content Reuse
Create modular content once, reuse across aircraft configurations and documentation types. The system tracks relationships and dependencies through envelope-level management, ensuring changes propagate appropriately.
Build content libraries that work for all manuals across an entire program, while maintaining configuration-specific accuracy.
Configuration Management at Scale
Efficiently manage documentation across aircraft configurations and customer fleets. Define technical criteria, such as modifications, that determine content applicability. For each data module, create configuration-specific versions and assign them to the relevant technical criteria.
Maintain separate tables that map which criteria apply to which aircraft serial numbers (MSNs), enabling automated filtering for specific operator fleets. When you publish to an airline, the system automatically delivers only the content applicable to their aircraft configurations.
This envelope-level approach handles the complexity of modern aircraft programs—managing thousands of configuration-specific content versions—without exponential growth in authoring effort or manual tracking.
Built-In Validation and Quality Assurance
Catch errors at creation rather than delivery. Real-time validation checks ensure content meets ATA 2300 requirements and your internal quality standards before it leaves your organization.
Quality features:
• Business rules enforced during authoring
• Schema validation before saving content
• Consistent formatting across all outputs
• Audit trail for all changes
• Full QA workflow with approval process
Direct Airline Delivery
Export ATA 2300-compliant output directly to airline CustoTool instances or any ATA 2300-compatible system. Or use our converter to export to airlines’ preferred formats and systems.
Fleet-level and subfleet-level publication with automatic applicability filtering.
Integration and Ecosystem
Built for Seamless ATA 2300
Integration-Ready for Today's Reality
ATA 2300 is an open standard that any vendor can support.
As industry adoption grows, the ecosystem will expand—but today, we’re working with the reality of mixed formats across the aviation industry.
Leading the Native ATA 2300 Future
Airbus Helicopters is pioneering a complete end-to-end native ATA 2300 workflow—from manufacturer authoring through operator management to crew delivery. This represents the vision: seamless structured data flow with no format conversions required.
Bridging to Today's Reality
In line with our vision of modular systems and zero vendor lock-in, we’re developing bidirectional format converters that integrate ATA 2300 solutions into the existing ecosystem.
Our current focus is Airbus commercial aircraft format, with additional formats planned as demand requires.
Adopt Standards Today, not tomorrow
This approach means you can implement ATA 2300’s open, structured format immediately—gaining the benefits of intelligent content management, configuration control, and streamlined workflows—while maintaining compatibility with legacy systems upstream or downstream in your documentation chain.
You’re not waiting for the entire industry to convert.
You’re not locked into a single vendor’s ecosystem. You’re building on an industry standard while remaining compatible with today’s operational reality.
Why Openness Matters
You’re investing in an industry standard, not a proprietary platform. As OEMs adopt ATA 2300 authoring and viewer vendors add native support, format conversions become less necessary—and our solutions automatically benefit from these improvements.
Your investment remains valuable regardless of which vendors participate in the ecosystem or how quickly adoption spreads. The standard is the foundation; the implementations can evolve.
