Default 2018 IAC Proposed Knowns

From the IAC site -

The IAC Known Sequence Committee, consisting a highly experienced pilots in a wide range of aircraft, have issued their recommendaitons to the Board of Directors for the 2018 Known compulsory sequences that will be used in both power and glider categories next season. Those proposed sequences are available below in a downloadable PDF.

Comments on these sequences can be directed to the IAC Director who represents your region and iacrulescomments [at] gmail.com. Comments should be submitted no later than 1 November 2017 in order to be included in the Board's agenda packages.

The Board of Directors will meet in Oshkosh on 10-12 November and vote on these selections.

Noticed the K for sportsman is lower this year, 121 vs 133. Even more reason to design your own sequence.

Hope to get some wx and fly sporty this week. I like last years better.....

Although..... soon as I get these snaps figured out intermediate looks pretty fun to try out and seems well within the capabilities of the ASIIS.....

Very little negative G in the Advanced sequence. Even the Unlimited sequence is a little sparse on the negative G side of things. As we all know I'm a big believer in lots of negative G in Unlimited.

Hopefully the new sporty will entice more newbies to give a contest a go.
Definitely time to build your own free if you want a top finish, but I'm in favor of the new direction.

IMO, the 2018 Sportsman proposal is a fairly typical sequence and no departure from the past. Compared to this year's Known, this 2018 proposal is actually more friendly to pilots who do not have a Free. That 27K laydown 8 in this year's Known was a killer for those who did not have a Free. I gave lots of 6's on that figure not because they were badly flown, but because there are so many opportunities to make small deductions that add up. This year's Known required a little more attention to box position for those flying low performance aircraft but was perfectly flyable. The 2018 Proposal just has no Humpty and a slightly easier spin. Nothing unusual or problematic with the Intermediate or Advanced proposals IMO. In Unlimited my S-1S will have issues flying off the top of Fig. 2. Fig. 3 will be interesting and snap speed on top of Fig. 5 won't be too impressive. Those neg snaps from +G lines (and vise versa) are a little annoying. Look forward to giving it a try.

Yeah, I can say with great conviction that I really disliked those,,,, OK, I hated those. Very awkward maneuvers to fly and when you were practicing them you just knew they looked awkward from the ground too.

Yeah Eric Muller once said something to the effect that those snaps were about as elegant as smashing a Ming vase.

Flew 18 sporty today in the ASIIS. Way easier energy managment from 17 but i like flying 17 better. Just sorta boring to me with no cross box figures. Everything flows very well and its easy to fly figure to figure keeping it tight in my non existant box. Flew it 3 times. There is alot of focus on 45* lines which is good cause its something i need to work on. Figure 9 is fun. I like the 1 1/2 spin better than this years but it would have been fun if the put a 1/4 roll in the hammer and then followed by something else with a 90 deg turn. Seems a great sequence for decats and rv’s though so hopefully some good turnout? Anyways, seems a good reason to design a free for next year and looking forward to my first competition!

No cross box figures may seem boring, but if there is a strong wind towards or away from the judges, it will get exciting very quickly.

Figure 9 is fun, but make sure that your drive figure 7 all the way into the wind because that downwind 45 on figure 9 will eat up a lot of real estate.

I always do a free in Sportsman and highly recommend it, it made the whole experience a lot more fun, from creating the sequence, to having a second sequence to practice and having something different to fly at a contest. Good to see I am not the only one practicing already......

At Nationals there was a 20KT crosswind. A flight program with no cross-box figures is pretty challenging in those conditions.

I got to be a wind dummy. Emphasis on dummy. My scores for that flight reflected that.

Best of luck,

Wes

The Unlimited Known is a little rough on altitude in my airplane. Dropped 2,000' after the first 4 figures today.

Actually 2,300' after 4 figures on some initial practice of this sequence the other day. Just the first few figures. This one's gonna be tougher to make passable than this year's Known.

Heres my rough attempt at the 2018 Advanced known, first time ever flying an advanced sequence. Side note, I gave myself a 3000' floor. Hence the rushing towards the end of the sequence but fun none the less.

Nice. (Although I had to view it twice. The first run I just watched facial expressions.)

I have an aresti question on fig 5. in the Advanced (roller) 2.2.3.1. Which of those 2 options is the right way to fly it?

A) 360 degree roll back to upright while having turned 90 degree (finish on the Y) immediately followed by a 180 degree roller to inverted while completing the remaining 90 degree of turn; I guess I'll note this 90(360)+90(180)

OR

B) 3 even 60 degree components with half roll for each. 60(180)+60(180)+60(180)

More generally, are there any roller that have none regular "checkpoint" (headed X and Y axes while passing inverted or upright), such as 60 degree or 120 degree (kind of like option B)

Thank you!

I'm certainly no certifed judge and I'm sure Eric or Wes will chime in here (please do if I get rule interpretation wrong) but the roller you speak of a 1 1/2 inside roll around 180 deg heading change. The rule is that you have to have constant heading change and constant roll rate throughout the maneuver. What you are describing above are ways judges break down the maneuver to judge weather the roll rate changes they are not supposed to downgrade you if you don't hit each break down point but they are supposed to evaluate how bad your rate changed. Here is what the rule book says on the subject:

To help visualize the execution of this figure and facilitate a way for the Judge to determine a constant roll rate, consider an aircraft performing a 360 degree rolling turn with 4 rolls to the inside from upright (Family 2.4.7.1). First, on the prescribed entry heading, the pilot initiates a turn and simultaneously begins a roll in the same direction as the turn. The judge will expect the aircraft to be inverted at 45, 135, 225, and 315 degrees and to be upright at 90, 180, 270 and 360 degrees. At these interim headings, the Judge will NOT downgrade using the one (1) point for five (5) degrees rule, but will judge changes in the rate of roll, changes in rate of turn, and changes in altitude (see downgrades below). At the end of the figure the aircraft must be wings level and on the prescribed heading.

So with that all said I would say to keep a constant roll rate you would need to fly it like you suggested in option B) Again please anyone correct me if im wrong.

What Bret said. The judges are not supposed to use the "checkpoints" for grading purposes, but if we see that a pilot is over or under one of the "checkpoints", this is pretty much broadcasting something the pilot's gonna need to do to make up for it - as in making a change to the turn or roll rate. And that's where the downgrades are made. So as a pilot, you should still make an effort to hit your "checkpoints", since you logically must hit them in order to do the roller with precision.
