Wayne,,
WHERE do you find this...?

I looked at the mini-iac page and could only find
seq's and the aresti's diagrams...

Thxz,

[loan4utoo]

Thanks Wayne, that's some great info.

[Carlos Vargas]

thanks wayne

[Wayne]

Robby,

I typed it out myself.
Now go out and learn to read the Aresti so you dont need a written description.

[bodywerks]

LOL!
I will be getting back into IMAC this year I think...I have the intermediate sequence in front of me now. Back in the day, I may have been able to do advanced, but with rules similar to pattern now (it used to be based on IAC, right?), and snaps (the right way) being such a HUGE deal, I figured I better take a step back. From what I understand, you can always move up, but never back in class, no?
Also, Wayne, wher do we find the criteria for what judges are looking for for each maneuver and the lines formed, etc.? I know that a snap has to have a pitch departure from the direction of flight, roll rates for other maneuvers have to be the same, as well as radii, but I don't know if they had thes "shark's tooth" maneuvers back in the mid-early 90's...are they looking for a dramatically sharp pitch angle, or just a similar radius to what we use to, say, exit a downline? That's the kind of info I need...

All the rules are on this page.

On the sharks tooth. All corners must be a flown radius, none of the 3 corners have to be the same radius.

I think the rules are closer to IAC then pattern. Figures in IMAC are wind corrected, this would not work with IAC. Even though roll rate is not a criteria, IMAC judges seem to judge the slower rolls better then the fast rolls. This is another area that pattern has influenced IMAC.

In pattern you have to show the break before a snap. IAC and IMAC the break and autorotation can happen at the same time. This is another area where some IMAC judges don't seem to know the rules. Snaps seem to be the cause of more aurguments then any other topic in aerobatics. The rules seem clear to some but not to others, things like the showing the break, displacement, loaded or unloaded snaps (oh I mean loaded or cheater snaps,lol). Lots of discussion but nothing is ever resolved, it is like a red state/ blue state fight.

[wmat7039]

6- 1-1/4 negative spin, vertical downline, 1/2 inside loop (X-Box), vertical upline, 6 points of an 8 point roll, push to upright exit.

Hey Wayne..... It should be (Y -Axis) instead of (X-Box)

Thanks! That's what I mean about it being more like pattern theses days: snaps and the way they're judged (or improperly judged!), lines being wind corrected, and roll rate having an influence on the judges...sometimes I think you have to know someone or be known to do well in these competitions...

If I may so bold as to point out. . . Figure #4 is NOT writen correctly. . .

figure#4 is a Down LOOP, and the plane must follow the radius of the loop throughout the maneuver. As it is written in this nomenclature, it is separated into 2 half loops, with a joining 1/2 roll/opposite full snap.

To properly fly this maneuver, the plane must maintain a constant AOA change throughout the maneuver, prescribing a round loop, with the 1/2 roll/opposite snap CENTERED on the bottom of the loop. This means, if you start the 1/2 roll at 7 o'clock (flying counter-clockwise), the Snap must end at 5 o'clock, with the 1/2 roll ending before 6 o'clock, there being a short pause wings level across the bottom of the loop (I mean SHORT. . 3-4 plane lengths maximum), then the Snap is initiated and ends at 5 o'clock on the curvature of the loop, and then the plane continues that arc until it reaches the original starting altitude and position l-r in the box.

[Judge]

Almost correct. The starting at 5 o'clock and ending at 7 o'clock is fine. The where stuff happens on that segment is wrong. There is absolutely NO REQUIREMENT for where the internal roll elements occur. ALL that matters is that the line segment described by the roll element segment is centered on the loop. In other words, say the roll element segment require 40 degrees of arc to complete (it could be 60 or 20 or whatever. The length of the arc is irrelevant) then you will need to have 160 degrees of arc both BEFORE and AFTER the roll element segment.

Where the roll elements occur on that internal line segment does not matter.. There is NO REQUIREMENT for the 1/2 roll to stop at a certain point or for the snap to begin. ALL that matters is that whatever length of that segment is centered on the loop.

For example say it was a 12 of 8 (1 & 1/2 8-point rolls) followed by an opposite 1/2 snap. It matters not one little bit where those elements happen on that line (loop arc) segment. All that matters is that the length of the loop arcs before and after it are the same.

This is not different than the case of a vertical upline. If there was an 8-point roll followed by a full opposite snap all that matters is that the line before and after that roll combination is the same. It would not matter where the pause between the two was relative to the overall line or the line segment they occur on.


With regard to the pause between the two roll elements, the rules are a bit vague saying only that there be a momentary or brief pause. I downgrade this like an Immelmann. If there is any visible line I give a 2-point deduction. Longer and I take more points. Also, the rolls MUST occur on an arc line the same radius as the loop. There is a MINIMUM 2-point downgrade for flying them on a flat line then continuing the loop.
