Looks like a keeper
This is now much more than a simple definition. A bit more than a stub. --Colputt 01:44, 14 September 2007 (UTC)

"slats" being considered retractable by definition
I corrected this earlier, but it seems to have been reverted. A slat is not necessarily retractable, although it often is. The definitive difference between a slot and a slat is that a slot is a notch cut out of an existing airfoil, while a slat is formed by an add-on structure outside the defined airfoil. I need to hunt down some support for this, but I recall this being the definition used in all of my aerospace engineering textbooks.

To be clear:

 * This is an interesting issue, one that we have been around before in this article. The main problem is that there are lots of expert textbooks on this subject and they all disagree. The one I cited, From the Ground Up is considered "the" definitive textbook used in Canada and it says if they move they are slats and if they don't move then they are slots, but there are other sources that say that slats can be fixed and slots can move. There is no agreement, so I have picked the clearest definition and cited that. I think if we are going to go the route that slats can be fixed and slots can move, then the whole article should be merged into the slats article, although this was proposed before and did not pass. 00:41, 2 October 2007 (UTC)  —Preceding unsigned comment added by Ahunt (talk • contribs)


 * Just a comment several years on, the slat vs slot semantic disparity remains in the literature. I agree with the position advanced in the article and above, and the differentiator should be whether the device is movable or attached to an existing wing (slat) or conceived by the designer as integral to the wing (slot.) Whether it is a separate physical structure is immaterial. The Zenith designs for instance locate the aircraft datum at the leading edge of the device, which would indicate that he considers it integral to the wing.

What purpose do they serve?
I read this article trying to find out what slots are, but the article doesn't actually say what they are for, what is their purpose? Comrinec (talk) 19:19, 9 July 2008 (UTC)


 * You are quite right - an obvious deficiency! I have amended the opening para to be more clear - diff - how is that? Ahunt (talk) 20:22, 9 July 2008 (UTC)


 * plane does not stall on low speed (delays stall) when slots are extended during take off and during landing, especially when airport is located much higher than sea level where the air is very thin.(Avraam Antoniades Panayia Cyprus) — Preceding unsigned comment added by 213.7.224.149 (talk • contribs) 19:06, 31 January 2014‎
