Built on machine learning, 418M+ data points, and seven years of iteration — Windsock is how aircraft valuation should work in 2026.
Mission
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
Not quarterly snapshots. Live market signals updated continuously — what each specific aircraft is actually worth right now.
Drop a logbook, maintenance record, or photo — get a full 20-page Windsock report in 20 seconds. No manual work.
300,000+ aircraft tracked. Full ownership history, ADS-B flight activity, accident records, AD compliance status — searchable in seconds.
Machine learning models trained on historical sales predict where each aircraft type is heading — not just what it's worth today.
Automatically matches installed avionics, modifications, and STC configurations to adjust valuations — precision that generic calculators miss.
We put money behind our data. If our reported value doesn't match documented reality, we'll review and refund within 24 hours.
