message: What is are the "five year plans"? GregInCanada 03:25, 4 April 2007 (UTC)
replies: text: Try Five-year plan, and then Five-Year Plan (USSR). The plans in China are based on that developed by the Soviet Union, so that article should explain the basics. That's really all I know, or else I would try to elaborate, but it should give you a start. - BillCJ 03:39, 4 April 2007 (UTC)

message: This article lists the engine thrust as 15332 lb.  However, the Aviation Week & Space Technology issue for 29 October, 2007, p. 64 lists the engine thrust as 18500 lb.  Somebody should make the effort to find the correct rated power for this engine type.  Any help would be appreciated. Raymondwinn 10:59, 16 November 2007 (UTC)

message: What's with the inconsistent order totals in the table? If you add up the orders, you get 248, which is what it says in subtotal, but under totals, it gives 208 total orders, which isn't even consistent with the reference it cites.  Given this, it seems like the total should be 248, plus 20 options, which also seem to have disappeared.  Could someone fix that, please? I'm not good with editing tables, so I'd rather have someone who knows how fix it.C628 (talk) 16:26, 21 December 2009 (UTC)

thread_title:  Development 

message: The phrase "geometrical determination" (as in a service Antonov provided to the development) is, in American English, a non-standard phrase, at least in my many years of exposure to aviation development. It reminds me of reading English translations of Russian texts. The words are proper English but the meaning and intent are often unclear. In this case, it comes across as somebody from Antonov said, "Yes, that's the shape of an airplane" or "Yes, the actual dimensions of the airplane match the numbers on the blueprints." Can we have a better description of what this phrase is trying to communicate? HatCat (talk) 13:32, 24 August 2011 (UTC)

message: "...ARJ21's wing became damaged during static testing..."
This statement sounds a bit disingenuous. It makes it sound like there was a mishap (for instance, a dropped tool) that somehow damaged the wing. In fact, the wing failed below specification during an "ultimate load test" designed to prove the strength of the wing. See Aviation Week & Space Technology, 2011/09/12, "Plan For China C919 Airliner Hits A Snag" (online at AW&ST website).  — Preceding unsigned comment added by HatCat (talk • contribs) 20:19, 9 September 2011 (UTC)

If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting.
If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page.
If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request its removal, or alteration, at the request page on meta.
When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags.

thread_title:  Source of truth for orders 

message: I have tried to verify the claims of the airplane being a derivative of the MD-90, but the sources used in the article are merely speculative. Given the lack of reliable sources that directly state that it was a copy, and that the sources in the article don't claim that, I've gone ahead and removed it from templates and infoboxes, as this is a clear violation of WP:UNDUE, where the prominence of the assertion isn't matched by the strength of evidence. Does anyone have any actual sourcing for this? At this point, even the citations in the article doesn't even verify, so I'm not sure that keeping the allegations later in the text even meets guidelines Acebulf (talk | contribs)  06:17, 3 March 2024 (UTC)
