About Jetspec
An aircraft reference being rebuilt from the documents that issued the figures.
The same wrong number, everywhere
Look up an aircraft’s maximum take-off weight and you will find the same figure on a dozen sites. That agreement is not corroboration — it is one transcription copied twelve times, and when the original was wrong, or was a different variant, or was a marketing round number, every copy is wrong together.
There is a better source for almost every specification on this site, and it is public: the type certificate data sheet the certifying authority issued, and the airport-planning manual the manufacturer publishes for the people who have to fit the aeroplane onto a stand. Those documents disagree with the copied figures more often than you would like.
So each figure here is being read back to its document, and the document, revision, section and page recorded beside it. Where that has been done, the page shows a mark next to the number that opens the source.
Counted, not estimated
204 is a small fraction of the library, and saying so is the point: the rest of the figures are inherited from the project’s earlier, less careful years and are being re-sourced document by document. A number without a mark beside it has not been checked yet.
Sections that were advertised and are not built
This page used to list a fleet database, an airport database and incident reports as features, each with a tick beside it. The fleet table holds no aircraft. The airport table holds no airports. The accident table holds six records, and they cite Wikipedia rather than the investigating authority, which is exactly the kind of sourcing the rest of the site exists to get away from.
All three have been taken out of the navigation until they hold something. Their pages still answer, and say so.
What is real: 352 aircraft types and 18 airlines, with 297 photographs, each carrying the photographer, the licence and a link to the original.

Which is why the fields are the ones an operational reader actually looks up — wake category, approach speed, runway length, ICAO type designator — rather than whichever ones a data vendor happened to sell.
Found a wrong figure?
That is the most useful thing you can send. If you have the document that contradicts it, better still — it goes in with the correction.
