Eurocontrol Free Text Validator

The Eurocontrol Free Text Validator analyzes free-form aviation text for compliance with Eurocontrol constraints. It supports single-entry validation and batch processing, with configurable rule profiles to match standard or strict interpretation. It provides structured, machine-readable feedback consisting of error codes, severity, and suggested corrections, enabling automated pipelines and human review workflows. Localization options apply language-specific lexicons and date/time formatting preferences to accommodate EU operations. Intended users include ANSPs, airline operations teams, IT groups, and data-quality managers who must ensure messages, records, and entries conform to Eurocontrol constraints before submission. It can be integrated into data pipelines and audit processes. Core use cases include pre-submission checks for flight plans, ATC messages, and aircraft status entries, as well as data-entry validation for backend systems. The tool emphasizes domain relevance over generic text validation and supports scalable validation across many records.
The validator uses a rule engine to apply character-set restrictions, length limits, prohibited substrings, and formatting requirements, plus optional ICAO phraseology checks. It returns per-text results, a normalization pass, and a score; batch validation can produce a consolidated report for audits and traceability. Export options include JSON, CSV, and human-readable formats for downstream systems or compliance documentation.
