I dont have a PTS in front of me, but I dont think they are required anymore, however they are great for developing a good scan.
Basically, the vertical S, Pattern A and B (I learned S1 and S2) are a series of climbing and descending turns. For the S1, you would climb and descend turning in one direction, but for the S2, you would change the direction of the turn each time you reach the top of the climb and the bottom of descent. Also, each time you climb, you go 100 feet less than the prior climb. If you started at 3000, you would climb to 3500, descend, then climb to 3400, descend, and so on and so forth, down to 3200. You dont do a 100 foot climb if memory serves correct.
hope that helps

I'm an instructor at USAF pilot training, and we use the vertical S. We have four of them A,B,C, and D. Basically each one is a 1000 VVI climb for 1000' followed by a 1000 VVI descent for 1000'. (So you start at for example 5000 MSL, climb to 6000 MSL in one minute, and then descend back to 5000 MSL in the next minute). Repeat as often as you like.
Vert S. A- Hold a heading, 1000 VVI for 1000' up, and then down (or down and then up).
Vert S. B- Same thing, except in a 30 degree left or right bank the whole time- At the speeds we fly, that's a standard rate turn, so you do a 360.
Vert S. C- same thing, except now you reverse the direction of the 30 degree Bank at the top of the climb
Vert S. D- same thing, except now you reverse the direction of the 30 degree bank at the top AND bottom of each leaf.
See AFMAN 11-217 vol 1. (Air Force's instrument reg). linked here: http://www.e-publishing.af.mil/pubfiles/af/11/afman11-217v1/afman11-217v1.pdf. Refer to pages 32-34.
BTW the file is pretty big. 34.50 Mb! Dialup users plan accordingly--go get a sandwich! (Across state lines, maybe?)
