Keel effect[edit]

Dicdef, only one source, unlikely to be expanded. Full of buzzwords and techincal terms, doesn't seem notable. Prod declined without comment. Ten Pound Hammer • ^{(What did I screw up now?)} 19:06, 28 August 2017 (UTC)[reply]

Delete: Stated to be an aeronautical term but it is definitely not in use in mainstream aeronautical literature. This article was initiated nearly a decade ago but has since been abandoned in a poor state. Dolphin (t) 22:07, 28 August 2017 (UTC)[reply]

Keep The article may have been in an imperfect state since 2007, but this discussion on StackExchange demonstrates that it has been useful to others. It gets 600 visits a month, which is not bad for such a specialised topic. The effect is real, non-trivial, of interest to a wider audience - [1], [2], and the information can be verified in reliable sources. The current wording may be a little technical, but we don't require every article to accessible to general audience. A quick search shows that the term is commonly used by aviators.

Relisted to generate a more thorough discussion and clearer consensus.

Keep it has potential to be expanded beyond being a DICDEF. A Guy into Books (talk) 07:57, 5 September 2017 (UTC)[reply]

@Aguyintobooks: ^{[citation needed]}. Where is the proof that this is a notable topic? Ten Pound Hammer • ^{(What did I screw up now?)} 00:46, 7 September 2017 (UTC)[reply]

@TenPoundHammer: It is a specialist aviation topic, so you won't find it in general news. Some specialist publications use it as a term, some have more detail, I would compare this to a mathematical topic. See.^[1]^[2]^[3] Note also that this topic is referred to as 'pendulum effect' or pendulum 'stability'

Keep - This is an aeronautics engineering topic. WP:NOT#DICDEF does not apply. ~Kvng (talk) 15:31, 5 September 2017 (UTC)[reply]

@Kvng: So being a topic means WP:NOTDICDEF doesn't apply? That makes sense. How is this a notable thing? Ten Pound Hammer • ^{(What did I screw up now?)} 00:46, 7 September 2017 (UTC)[reply]

Significant coverage in multiple reliable sources: [3] ~Kvng (talk) 02:33, 7 September 2017 (UTC)[reply]

I've been an aeronautical engineer and pilot for close to four decades and I've never heard of it. It's probably notable in naval architecture, but it isn't in aeronautics. Dolphin (t) 01:11, 7 September 2017 (UTC)[reply]

It does show up in a lot of books written for pilots. ~Kvng (talk) 02:33, 7 September 2017 (UTC)[reply]

Keep or merge. This is a basic topic in the the design of lateral stability of an aircraft. It is also called the pendulum effect. See for instance, training materials describing lateral stability for an FAA test, a a flight tutorial, and all the aviation manuals Kvng pointed out. It is often discussed along with dihedral or anhedral configurations, so it would also be fine to merge into Dihedral (aeronautics)#Vertical position of the center of mass. --Mark viking (talk) 05:39, 7 September 2017 (UTC)[reply]

Thanks Mark viking I have created a Pendulum effect redirect. 15:06, 7 September 2017 (UTC)[reply]

Keep or merge to the section highlighted by Mark viking. I lean towards merge. Burninthruthesky (talk) 15:54, 7 September 2017 (UTC)[reply]
Weak keep As stated above, a merge would likely be best, but if not accomplished I suppose it wouldn't hurt to keep - that is, with proper upkeep. This article seems to have been left for dead, but I can see it having its uses in some medium! Bryan C. W. (talk) 19:28, 7 September 2017 (UTC)[reply]
