Mission

Accurate aircraft valuations, on demand. The same data clarity that car and real estate buyers take for granted — finally arriving in aviation.

For decades, aircraft owners had to choose between one-size-fits-all calculators or expensive professional appraisals. Windsock ended that. We built the tool the market needed: real-time, aircraft-specific, grounded in what's actually selling.

Capabilities

Built for how aviation actually works

Real-Time Valuation Engine

Not quarterly snapshots. Live market signals updated continuously — what each specific aircraft is actually worth right now.

Autopilot Report Generation

Drop a logbook, maintenance record, or photo — get a full 20-page Windsock report in 20 seconds. No manual work.

Aircraft Registry Intelligence

300,000+ aircraft tracked. Full ownership history, ADS-B flight activity, accident records, AD compliance status — searchable in seconds.

12-Month Price Forecasting

Machine learning models trained on historical sales predict where each aircraft type is heading — not just what it's worth today.

Avionics & STC Matching

Automatically matches installed avionics, modifications, and STC configurations to adjust valuations — precision that generic calculators miss.

Ground Truth Guarantee

We put money behind our data. If our reported value doesn't match documented reality, we'll review and refund within 24 hours.
