Anyone know if there is a video of the 2007 Sportsman Sequence? I am a newbee and there are some parts of the sequence that I don't understand ie. is there an exit and enter the box after #6? What is the maneuver after the vertical upline to set up for the split S? How do you do a double immelman?

Hope someone can help,
lee

I have been trying to fly some of the aneuvers on the sim to post, but end up fooling around. i will ty to put something together so you can see.

I've been doing the same thing but I don't want to practice the sequence wrong, that's why I need to see the correct way to fly it. Thanx for your response and I look forward to what you come up with.

Yes, you do exit the box after maneuver 6. To perform the vertical upline you will fly straight and level, pull up through 1/4 loop, fly vertical (centered of course), then, push down through 1/4 outside loop exiting straight and level. You will now be at an appropriate altitude to perform the split-s. The double immelman is like 2 half loops with flat spots at the top and bottom. To center the double immelman you'll have to go past center before pulling through a half-loop, fly inverted (not sure what the required duration is), and then pull through another half loop ending at the same altitude that you entered. Keep in mind, if flying left to right the pull for the first loop will be to the right of center, and when you finish the 2nd half loop you will be left of center in order to have the proper geometry. Hope this helps, and good luck!

(not sure what the required duration is), The required duration ( length of the inverted line at the top AND corresponding upright line at the bottom to finish the maneuver) is set by the size of your 1/2 loop which will in turn be set by the length of the beginning upright line past center to start the maneuver.
The reason I say this is because the double immelman is a square box with rounded ends(the 1/2 loops), NOT a rectangle Sooo
the distance you fly past center before you start to pull the 1/2 loop will determine your overall size. The 1/2 loop will need to be twice as tall as that line was long - then the inverted flight across the top will need to be as long as the 1/2 loop was tall.
MOST beginning flyers ( I know cause I did it) always make the top line too long and make a rectangle out of it. Quite often this is a symptom of a sport plane that lacks on vertical power to make the 1/2 loop tall enough.

Sorry this is so long winded - lots of words to describe something simple -but it's important as most ALL sportsman pilots miss this until it's pointed out to them. Check it out in the aresti

That's the description I was trying to remember, thanks swlarcham. An easier way to put it would be to say the straight line segments should be the same length as the diameter of the half loops. I agree most sportsmen miss this one. In the rounds I judged this year most of them made more of a rectangle in the middle... it ends up just looking like an extremely long oval.

Yeah but that is too easy and assumes you know the meaning of big words like segment & diameter.
I can't do anything the easy way
Anyway I thought if Lee didin't have the aresti maybe that willl help until Chuck can get the video made.

Us Loosianna boys ain't all about gettin our lern on... weez just grab tha transmitta an' fly!

UhoH Now you went 'an dun it. I tried to make dem las words widout no country/cajun slang but it musta comed across anyways[8D]
yeah yeah don read what I wrote , read what I meant.

If you were judging, what would you score lower the rectangle with perfect 1/4 rounds or box with shotty 1/4 rounds. Or would you just hit the errors the same?

It depends on the severity of the longer legs and/or the variances in the radii of the half loops. When it comes to the length of the legs or "box sides" you establish that length by how far you go past yourself before beginning the maneuver, and also the necessary radius you need to maintain throughout the loops. The downgrade is based on a percentage of how far off you are in each leg (I think), but one goofup can cause downgrades on the rest of the maneuver. Case in point: Let's say you fly 50 feet past yourself before pulling up. You have now established a necessary loop height (diameter) of 100 feet. Now let's say instead of climbing 100 feet during the loop, you top out 25 feet higher but the loop was "perfect" in that you maintaned a constant radius. You fly a perfect straight and level inverted flight 100 feet, and perform another perfect half-loop, exiting at the exact altitude at which you entered. Now, I'm just getting back into this, so I don't know what all the current standards are, but someone told me the point downgrades have something to do with the percentage you are off. Well, in this case you were 25% off in the height of the maneuver, and this should earn a 7.5. Keep in mind, that in this instance even though the loops were "perfect" they had a larger radii than were established when you began your pull-up. Now, 25 feet off isn't that easily noticable to the judge, and given everything else being perfect, it will probably score higher. The problem is, once you've completed that first half loop, your max score is established because you have already shown exactly how the other half of the maneuver should look. The best scores on this maneuver are earned by those who don't attempt to correct what has already been done wrong. You can disguse slight altitude problems by just holding what you've got and making it as pretty as you can with what you've got. If you try to gain or lose altitude while inverted, that's just going to cause another downgrade by not flying the inverted part level. Your question about a perfect box with shotty loop ends would be difficult to do (not judge, but actually do) because the box height is determined by the loop. But if this were to actually happen I believe it is a one-point downgrade for not having a constant radius to each of the loop, 2 points for more severe. I hope this helps, and I hope I'm right about the downgrades. Now that I think about it... check this out, it can answer all these questions a hell of a lot better than I can: [link=http://www.nsrca.org/competition/judging/guidelines.htm]NSRCA Judging Guidelines[/link]

OOppss.. I thought this was asking for IMAC.. Not pattern. Sorry
