For safety officers, not IT.

Industrial-strength FDR decoding, written in C++17 for speed

• • Fixed, variable, and superframe formats
• • NRZ, BCD, Discrete, SSM, Manchester encodings
• • Sync-word sequence detection with configurable patterns

Vendor-specific decoders that don't pretend the world is standard

• • Honeywell DLU empirical decoder (production)
• • Per-channel decoders mapped to recorder documentation
• • Multi-vendor architecture (Honeywell first, more to come)

Multi-GB FDR files, bounded memory, no batch jobs left for tomorrow

• • Memory-bounded streaming with configurable batch sizes
• • Direct PostgreSQL COPY via libpqxx for high throughput (optional)
• • HTTP/PostgREST fallback with exponential-backoff retries

Detect unstable approaches before the post-flight review meeting

• • Configurable thresholds per fleet + per airport
• • Sink rate, glideslope deviation, flap_angle_deg, ILS capture
• • Per-flight score + drill-down to the second

Bad data caught at ingest, not at the safety review

• • CRC validation on every frame
• • Range validation per parameter (configurable)
• • NCD (No Computed Data) and test-value preservation

See the flight, don't just read the rows

• • Primary Flight Display (PFD) recreated from FDR parameters
• • 3D ground track with India airport context
• • Scrubbable timeline — jump to the exceedance moment

Built for the Indian regulator from day one, not retrofitted

• • DGCA/DCDCA-aligned exceedance reports
• • Evidence bundle exports (parsed parameters + raw frames + audit log)
• • Submission-ready PDF + machine-readable CSV/JSON in one click

Every parameter has provenance, every change is logged

• • Per-parameter provenance — frame, slot, decoder version, decode timestamp
• • User actions logged (threshold edits, manual reviews, approvals)
• • Immutable audit trail with PostgreSQL append-only enforcement
