ACM... the Elbow.. (Attn Andy)
« on: January 11, 2001, 11:16:00 AM »
Halloo

I've read many articles on ACM, as well as R. Shaw's book.  I recently read Andy's articles at SimHQ.  I am a little confused as to the application of the Elbow.
In an engagement, should I pulling for the Bogey, or for the elbow?  
I engage a bogey, let's say a headon pass with very little separation.  Should I be lead turning the "elbow"?  or the actual bogey itself?  Should I be always delaying my pull slightly to position myself in the elbow?
I experimented briefly last night pulling for the elbow, and it seemed to work, though the only enemies I encountered were not names I recognize, so I assume they were newbies. (With the exception of catching Frenchy too low for his own good   while I had friends alongside)

I find Mouse's text difficult to apply, perhaps it is just my understanding of the text, and if i read it another 5 or 6 times I'll start to understand it better.  The ribbon diagrams while nice to look at seem narrow focused.  His chapters on the energy fight have helped immensely, it is in the angles fight that my weaknesses lie.

Advice?

Excellent question. This is something that I have to continually remind myself to think about when flying AH.

'Flying to the elbow' is a lag pursuit technique useful when attacking better turning targets when you are at relatively high angle off (or aspect angle). The idea is that the lag pursuit gives additional turning room for you to make the corner when converting to the target's six. It's important to note that this technique is used when your objective is to maneuver to the six o'clock of the target. If that is not your objective (let's say you want to go for a high deflection shot and then separate), then the 'elbow' technique is not the thing to do.

In AH, I see this most often when attacking a furball. I pick out my target and then visualize a point in the sky behind and above him. How far? Pretty far...a good twenty fuselage lengths, or about 1/4 of the width of the monitor screen. The more overtake (closure) you have, the more separation you will need. This maneuver looks like a High Yo-Yo flown at long range.

Turn to point your nose at your estimated six o'clock point. The target will likely be moving rapidly towards your monitor edge, so be ready to switch to a side view to keep him in sight. Now, if the target is still flying in the same general direction, roll your lift vector towards him and switch to a top (up) view or up 45 view to regain sight of the target. Now play your back pressure to pull the target down into your forward view.

If the target has changed his direction, you may want to continue your initial pull to the elbow (the 'yo-yo') while you watch him in your side view. You may not want to commit yourself towards him if he is taking away your turning room. In this case, you repeat the process over by turning towards his six while keeping your separation.

The following picture shows the point. Disregard target range...by the time you got to this range, you should have already pulled off to the elbow!

Ahh.... Lag Pursuit, one thing that marks the difference between an average pilot and an excellent pilot!

But its also one aspect of ACM thats the most difficult to learn.

I just love it when I hear... "How did your Pony (or Yak or anything) out turn my Spitfire !!!"

When actually the Spit pilot was just pulling the stick back into his stomach for a 9 G flat turn, when all I did was pull up into the "elbow" as you are calling it, drop my nose, and use my roll rate rather than my turn rate.

A very effective technique!

I suggest you begin with the "Its All a Matter of Perspective" series.

Additional info (some repetitive) is in the "BFM101" series, but not as well illustrated.
