Avidex
Look up what a plane is worth by its tail number, based on what similar planes are listed for right now.
People buying, selling or just keeping an eye on piston aircraft.
Sample aircraft

Model, year and engine
from the FAA registry
$59,107 Low confidence
Range $32,509 – $85,705
The 12 comparable listings disagree with each other too much to narrow this further, so treat the range rather than the figure as the answer.

What it does
Free aircraft valuations, built from real listings.
It checks about 25 marketplaces and brokers every day, so it can also show how long planes sit on the market and how their asking prices change. Each aircraft’s page pulls in its FAA registry record, accident history and airworthiness directives. It isn’t open to the public yet. The scrapers and valuation engine are working, and the market-trend pages are still filling in as the nightly job collects history.

The comparables
Twelve Cherokee 140s for sale in September.
These are the listings behind the estimate above, from Barnstormers and four broker sites. Avidex re-checks them every day, so it can tell how long each one has been listed and when the price moved. Days count from the first time Avidex saw the listing. A dash means it’s only been seen once, and Avidex won’t guess a number from one sighting.

Where it’s weakest
The methodology page lists its own gaps.
Every number on a valuation traces back to the listings it came from, and every adjustment says whether it was measured from the comparables or taken from a default. These are the parts Avidex can’t measure yet.
- 01
No sale prices
It only sees asking prices, so it takes 6% off for a piston single and says so on its own line.
- 02
Thin models
Rare types don’t have eight comparables, so the comp set widens to the model family or two years back, and the range gets wider.
- 03
Self-reported condition
Hours, damage and logbooks come from whoever fills in the form.
- 04
No regional adjustment yet
It’s built and switched off until there’s enough data to back it.
