IMAC maneuvers
Hello,
I'm just starting to get more into pattern flight and was wondering how to determine the center line when looking at the IMAC sequence diagrams. For example, what orientation should the plane be in between maneuvers or within a maneuver when it is dead center of the pilot and jugdes. The NSRCA diagrams clearly show the orientation and position of the plane at dead center.
Thanks.

RE: IMAC maneuvers
You're not going to like this, but there is no "center" in IMAC. Figures get placed where they are in the flow of the sequence and may, or may not, be "on center". There is no criteria to "center" as in pattern. Go to the AMA website and download the Scale Aerobatics rules. Read the section on the Airspace Score.

RE: IMAC maneuvers
You will learn that IMAC gives the pilot the freedom to present the entire sequence in any position relitive to the judges. Depending upon the sequence some are best started in front of the judges and others may lend themselves to beginning at one end of the field. In IMAC its up to the pilot to present the sequence of manuvers to the judges so that each manuver may be easily viewable and thus judged. This year the guys at IMAC did a great job putting the class knows together and they are easily presented. The ACS score is "Airspace Control Score" and is a 0 thru 10 score based upon how well you present the sequence to the judges. You will find all this information on the IMAC site. What class are you flying and where do you live? Tulsa is having its contest May 15th if you can make it.
Here is the info from the IMAC site.
"The following standard will be used for assessing the pilot’s performance in maintaining control and awareness of the aerobatic airspace and placing figures in the airspace in a manner that allow the figures to be optimally judged. vThe HIGHEST standard for Airspace control: vThe pilot that exhibits a significant ability to control the location of the aircraft inside the Airspace, relative to the Judges, resulting in a tight footprint and locates the aircraft that it can be optimally judged at all times should receive a TEN (10). v vThe LOWEST standard for Airspace control v vThe pilot that exhibits a poor ability to control the location of the aircraft inside the Airspace, relative to the Judges, resulting in an excessively large footprint and has the aircraft consistently so far away as to be difficult to properly judge. This pilot exhibits a very poor Airspace control and should receive a zero (0).
vPilots exhibiting Airspace control within the range of these two standards will be graded with a range of possible scores from ten (10) to zero (0) in whole point increments.
vK factor for the Airspace Control Scores for Sportsman class is 6K"

RE: IMAC maneuvers
Thanks for the information guys. I'm practicing intermediate in both IMAC and pattern.
I'm out in HI and unfortunately we don't have any contests out here nor is there a big community of pattern fliers.

RE: IMAC maneuvers
Yes!
when I practice....
I'll go through the sequence a few times... then go back and work on specific maneuvers....
if while I'm doing a sequence, I really flub a maneuver, I'll bail and and do it again.....
then I'll just practice various maneuvers that I have seen and had troubles with in unknowns..... and try and tie several together...

RE: IMAC maneuvers
Take special note that you need to be very proficient with the high K factor manuvers since they have a huge impact on your score. Hammerheads, snaps ect.
I practice the full sequence as well as each manuver and specific elements of said manuver, such as point rolls, snaps ect... That said, if you are flying a specific manuver, try to practice it where you will present the manuver within the full sequence. This way the sight picture is the same.

Bill not true.
You need to be a paid IMAC member to view the training library.
Which is a pile of crap as new flyers need this info.

RE: IMAC maneuvers
Where can one find clear explanation of the Aresti System symbology? I saw a link on the IMAC site that involved down loading Flash Player which I would rather not do. I come from three decades of AMA pattern, clear drawings of aircraft attitude etc. Would appreciate some advice as I am considering the jump to IMAC, thanks.

BAH!! RCU blocks out the domain!
Do a google search for Aresti Made Simple and that should get ya going....

They are a tiny bit dated due t the addition of 45 degree entry and exit lines on Hammerheads, but they are more than fine to get people up to speed.

RE: IMAC maneuvers
from a level horizontal line
Pull to a wind corrected, wings level vertical upline
Pull to a wings level inverted 45 degree downline
execute one half roll to upright
Pull to a wings level, wind corrected horizontal line
Things to look for
The pulls must be the same radius with the first pull dictating how the rest of the pulls should be done, the half roll must be centered on the 45 degree line
Sharp pulls are a no-no
and will get points taken off
The vertical line can be as long as you like, same as the 45 degree line, just make sure you have a line before and after the roll on the 45 and that line MUST be equally, this is the biggest points killer of them all.
Most important, you wings MUST remain level at all times and the proper amount of wind correction must exist at all times.
You are not judged on the "look" of the plane, you are judged on the track of the plane, which means the CG must remain on a given line at all times. You could be pulling a vertical line, yet be yawed to one side 30+ degrees and that would be perfectly acceptable as long as the CG is tracking a perfectly straight line

Family 1.12, Page 15 of the AMA rule book (on the IMAC site), SCA-15, Figure 17. Radii A, B, and C may all be different.
Hope this helps,

RE: IMAC maneuvers
BTW, you answered my question on the Cap the other day and to let you know I flew it last night and OMG what a puddy tat she is. I used 1 degree positive, balance on front of the wing tube and just perfect for my style of flying. Absolutely no elevator trim, hands off inverted 45 degree upline pulls to the nose ever so slightly. Weight is roughly 39lbs on a DA170 on MTW110K cans and yes I am still able to get to the front wing bolts, I used a set I had for my Jtec 330L and just leave it in the fuse with the threaded part hanging out and I can just get my hand down between the can tunnel and fuse side
Now I remember what I was missing when I lost my last Cap. This one and I will have a very long relationship in IMAC....
Thanks again for the help on that one

RE: IMAC maneuvers
Bill: I'm from the "school of hard knocks" with the Caps. Flew three of them in Unlimited, had some very special trimming and mixing going on to keep er' straight. I loved my Caps, they freestyled the best. Glad to help out,
Dan,
