How we check what we publish

The rule that governs everything else

We do not publish a number we cannot source. Not an approximate one, not a reasonable-sounding one, not one carried over from another website. A specification we do not hold is shown as not recorded, and the database stores it as null rather than as a zero or a guess. This is why some pages look sparse. Sparse and correct beats complete and invented.

Aircraft listings

What we check and what we do not

Listing content is written by the seller. We check that a listing is for a real aircraft type, that the images are not obviously reused from another advertisement, and that required fields are present. We do not inspect aircraft, verify logbooks, confirm hours, or assess airworthiness.

Prices shown are asking prices as entered by the seller. They are not valuations, not transaction prices, and not evidence of what a type is worth. Where a brand page shows a price range, that range describes the listings currently on this site and nothing wider. We suppress the range entirely when fewer than three listings exist, because two data points are not a market.

Manufacturer records

Manufacturer details come from the manufacturer's own published material or from a civil aviation authority register. Each brand record stores the source URL and the date it was last checked, and both are shown on the page. A founding year we cannot source is left blank rather than inferred from a company registration or a magazine article.

Training schools

Approval references

We reproduce the approval reference a school publishes about itself. We do not confirm that the approval is current, and we are not a regulator. A school appearing in this directory is not an endorsement and is not evidence of anything. Check the school's status with your national civil aviation authority before you pay for training.

Articles and authorship

Attribution

Every article carries a named author. The author record holds the year they became active in the industry, and the years-of-experience figure shown on the page is calculated from that year rather than typed into the copy, so it cannot silently go stale. Where an author holds licences or ratings relevant to what they are writing about, those are listed, and only when they are held.

Review

Articles covering airworthiness, maintenance or flight safety carry a named technical reviewer and a review date. Both appear on the article. Safety-relevant articles carry a scheduled next review date, and the publishing system tracks it.

Structure

Articles run between 750 and 1,250 words, use heading levels in sequence without skipping, and break up long stretches of prose with a comparison table, a decision matrix or an expert call-out at least once every 300 words. These are enforced by a publish gate, not by good intentions. An article that fails any of them cannot be moved to published status.

Sources

Claims of fact are cited to a numbered source list at the foot of the article, with the publisher and the date the source was retrieved.

Corrections and complaints

If we get something wrong, tell us and we will correct it. Substantive corrections are noted on the article rather than quietly edited away. Send corrections to the postal address on our privacy page, marked "correction". Tell us what is wrong and, if you can, where the right figure comes from. We would rather be corrected than be consistent.

Commercial relationships

Nothing on this site is currently paid placement. Manufacturer listings, the training directory and the order things appear in are editorial, and no brand has paid for position in any of them. If that changes we will say so here and label the paid item where it appears, every time. A directory that sells position quietly is worth nothing to the buyer using it.
