Talk:Slip (aerodynamics)

message: The 2nd paragraph under "Sideslip angle" needs support, either by explanation or citation.  The first sentence could be describing angle of attack as well as sideslip angle.  As for the second and third sentences, I don't understand why these would be true, or why turning is relevant to the sideslip angle; this should be explained.     — Preceding unsigned comment added by BobSundquist (talk • contribs) 14:08, 2 August 2013 (UTC)

message: The graphic that is currently used gives a false impression of the definition of beta: for positive angles beta, the relative velocity vector points to the right of the nose, not to the left as currently shown. When looking from the top on an aircraft flying horizontally, the angle of sideslip is defined positive clockwise. Refer to the first page of this for details:  Hopefully somebody can adjust the graphic to show this.  — Preceding unsigned comment added by 2A01:C22:7A3F:4D01:DDB5:8516:4405:DD0 (talk) 07:53, 18 January 2022 (UTC)
thread_title:  Direction of positive sideslip angle beta 

message: I think that the page sideslip angle should be merged into this article, seeing as it is a part of the sideslip itself and the sideslip angle page provides information on calculations that I think should be included in this page.

thread_title:  Merge? 

message: Whoever wrote this page, you are confused between sideslip and forward-slip. Definitions are correct though, it is just the names. If you think I am wrong, do some research or leave a message and I will quote you the definition form a book. En51cm 02:12, 7 November 2006 (UTC)
thread_title:  Older talk comments 

message: This reader also confused .. the first sentences of Forward-slip and Sideslip appear to describe exactly the same procedure.  Track and Heading are surely the same thing, in this context, both being relative to the ground?  That is, the track is the vector over the ground that the aircraft is following, and the heading is the bearing (direction) component of that track (as opposed to where the nose of the aircraft is pointing).
Some clarification is needed, one way or another... quota (talk) 17:39, 2 December 2008 (UTC)
replies: text: Under normal flight conditions and with zero wind (or direct headwind or tailwind) heading and track will be identical, heading being the direction the nose is pointing and track being the direction the airplane flying. It is possible to set up the aircraft so that it will not fly in the same direction in which the nose is pointing. For example, if the pilot applied right rudder (while countering the effects of roll produced by the rudder) the aircraft will have the tendency to remain on its original track even though the direction of the nose has been yawed to the right. The aircraft is indeed turning, but only slightly. It is essentially flying somewhat sideways and its track is largely unchanged by the yaw. When the rudder is released, the aircraft will have the tendency to have its nose swing back to the direction of its track. Another example of this is the forward slip. On final approach, the pilot may judge that the aircraft is too high and may want to bleed some altitude. The pilot will yaw to the right and maintain right rudder throughout, and then roll to the left (in that order) while pitching down slightly. The pilot is now in a forward slip and will notice that although the longitudinal axis of the aircraft is not inline with the runway, the direction in which the aircraft is flying is still parallel to it. Hope that clarifies things a little. Perwisky (talk) 21:14, 4 June 2009 (UTC)
thread_title:  Forward or Side 

message: I've noticed this is written from a "pilot" point of view (mostly).  That's okay, even good, because a "slip" is more pilot language while "sideslip" (see Sideslip angle) is more aeronautical engineer language, and the name of the article is "Slip" after all.  :-).  
I would like to make it more explicit about what is "pilot speak" and add a little "engineer speak" with references to the Sideslip angle article.  That way we can clarify things like:
*In the pilot world a slip and a skid are different, but they are the same to an engineer.
*etc.
I'll take care of those changes "sometime soon". :-).

thread_title:  Written from a Pilot POV 

message: This article is all over the place.  It covers things that are off-topic.  It covers things that are covered elsewhere in Wikipedia.  It is incorrect on many points.  It is haphazard in organization.
I'm warning anyone who cares that I'm gonna tear it up and put it back together right.  :-).
I'll try to "be nice" and post big changes for comment.
It might end up much smaller than you're used to.
It'll be MUCH BETTER.  Trust me.  :-).
Anyone got any problem widat?
Anyone wanna help?
Speak up!  :-)

thread_title:  Needs major reorganization. 

message: I am a pilot as well as an aeronautical engineer.  I know that often "pilot speak" is different than "engineer speak".  It is frustrating sometimes to see something so gosh darned simple as Angle of sideslip be made so complicated when put in the required language of traditional pilotspeak.  Even so, I do understand the "pilot's eye" differences between:
* Forward Slip
* Side Slip
* A turning slip
* A turning skid, and
* An uncoordinated "turn" (or better, "uncoordinated roll")
Even though these are all almost exactly the same gat-danged things, the differing contexts make them different things to a pilot (or to an easily confused layperson).  It shouldn't, but it does.  Pilots are taught wrong about this in my opinion.  For historical reasons, they're taught that way and I can't change it until I start a flying school and write a great book like Langewiesche or Kershner.
Anyway, I know what all those things are even in pilotspeak, but I don't know what the current Forward Slip and Side Slip text is really trying to say.  It's written like a Pilot "How-To" manual, but I don't think that's what we need.  I think it has the hand of many authors trying to fix it little by little.  It darts about , changing subjects quickly while it tries to talk about everything. I'll fix it up better.  "Trust me."  :-)
Hmmm...  It seems that a FS, and a SS, and a turning slip, and a turning skid are pilot maneuvers where a pilot gives the plane some amount of sideslip angle in one direction or the other either by mistake or for some operational purpose.  Hmmm... maybe I'll put things in that context.

replies: text: I am also a pilot (private and glider) as well as a mechanical engineer and I have to disagree with you about all these types of slips being "almost exactly the same gat-danged things." They are only slightly similar in that the aircraft in all these scenarios is "slipping" to one side (ie. the velocity of the aircraft has a component in the direction of the lateral axis). However, forward slips and side slips are initiated differently and are used for different purposes. Moreover, they are essential in the pilot's arsenal of maneuvers. I've heard many people (including some pilots) refer to both maneuvers as side slips, much to my dismay. I am happy to see an article on the net that differentiates the two. I agree however that it is somewhat lacking in certain areas, but wikipedia is an encyclopedia, not a flight manual. Perwisky (talk) 22:10, 4 June 2009 (UTC)
thread_title:  Forward Slip and Side Slip - Hard to figure out. 

message: Removed part of sideslip section due to incorrect information regarding side-slip for altitude bleed in sailplanes... A forward-slip is much more common.  —Preceding unsigned comment added by 76.64.125.111 (talk) 02:49, 4 April 2010 (UTC)

thread_title:  External links modified (January 2018) 

message: Over 50 years around and in aviation, and I've never known the mastering of slips being required before a student solos. Perhaps this is something new, or something required in countries other the U.S. 
Forward slips are usually used in aircraft that don't have flaps, and have little practical application in modern aircraft. Some pilots like to do them to impress observers. There's always been too much similarity between forward slips and cross control stalls to suit me. Something you don't want a 10 hour student pilot messing around with, especially on final at low altitude. ~eelb53
