You saying we cant knife edge on the top while makeing it 4 wingspan wide

So if the aircraft starts to pivot before the vertical motion has stopped,

that is not a fly over, just downgrade 1 pt per 1/2 wingspan

or the pivot radius is larger than 4 wingspans (in calm conditions), a flyover has occurred.

correct

Hey Rick

Welcome back. Looking forward to flying together again.

Ted

[Rick Kroeze]

and to discuss some of the strange rules that Ted and Dave had to contend with at Tuscon.

Ted, can you fill me in on this statement?

Hi Rick

Not sure strange is the right word. The one I am not sure about in the rule book is on the hammer. On the vertical upline into the wind with the plane wind corrected (pitch only) for a strong wind, at the point of the pivot we were required to correct the plane so the longitudinal axis of the aircraft was vertical before we rotated. Once rotated we could then pitch again to wind corect the vertical downline.

The comments on the stall you make is what we had to fly, and what I tried to relay at the meeting but didn't say it correctly. We had to maintain a horizontal wind corrected flight path and at the point of entering the spin the plane just was to basically quite flying and break in all three axis simultaneously. If the plane was seen to drop the nose before it broke in the other two axis then it was a down grade .5 for 5 degrees.

The comment on the snap entry is as you describe, a simulatneous conically rotation of the tail and the nose about the centroid of the aircraft with no noticable line drawn after the nose pitch up. Therefore the way I understood it, it was not a requirement to see the nose pitch before autorotation started, it just had to be there through the autorotation.

I am writing this response under a time deadline I got to go to a meeting, hope I described it correctly this time. I have a hard time writing and speaking english, there are too many interpretations.

Bottom line I agree with everything you said Rick, no disagreement on the judging criteria you put forth.

Glad you are back, looking forward to getting together for that half way dinner still.

Once rotated we could then pitch again to wind corect the vertical downline.

This is something that was a surprise to me. I have been both flying and judging it incorrectly. I find it odd that we are required to correct this in pitch only and not in yaw. It seems like a contradiction. It is, however, how it is stated in the book. You must stand the plane back up to vertical in pitch, eliminating the wind correction. Once back on the downline the pitch needs to be put back in to maintain the track.

There are a few things, including this one, that seems to be a north central habit. When things like this came up in Jacksonville people in the other regions had a kind of matter of fact "of course that's the requirement". They've been doing it like that all along.

There are a few more things that could be posted if there is interest. I thought maybe post them individually so they can be questioned/discussed if needed.

Some of them might not be new to you but they were an eyebrow raiser to me.

Here is one:

It's not happening yet but they are getting ready, in a future season, to add 45 lines with roll elements to the entry and exit of a hammer. They are studying the repercussions because the potential for huge K factors is very high. You could have combination rolls on both the 45 lines as well as the vert up and down lines (egad!)

This has been prompted because it has been added to the FAI catalogue which we are basing our figures on.

Hey Rick, why not start a new post on the judging aspect of IMAC and what may be coming up (with pics please ) since I only read Aresti!! :P
