TomParsons Certificates/Ratings/Crew Stations: 10. "RE: Primary or Sportsman?" 05-13-02, 15:05z  Ben- I was about to talk about your specific questions, but I thought it might be helpful to back-fill with some basic information first. Competition aerobatic sequences are drawn using using Aresti notation, which is named after the aerobatic pioneer Jose Luis Aresti of Spain, who developed the basic notation. Each figure is composed of (usually) two or more parts: one basic maneuver (loop, hammerhead, half cuban eight, etc.), and (usually) one or more specific rolling maneuvers added as "garnish" to the basic maneuver. So for example, in the Sportsman sequence shown above, Figure 2 is a "reverse wedge", with a half-roll as the specific rolling maneuver. The roll could have been two points of a four-point, or a one-and-a-half roll, but here it is specified as a regular ol' half roll. As the level of competition goes up, the figures often have more (and more difficult) rolling garnishes added to spice them up. For a given aerobatic sequence, there are three sheets, or forms, on which the sequence is drawn: Form A, Form B, and Form C. Form A lists each figure in its own little section, complete with the official catalog numbers and difficulty, or K, factors for each part of the figure. Forms B and C show the figures strung together in the sequence, and look like mirror images. The only difference is that Form B shows the sequence oriented for wind from the right, while Form C shows the sequence as flown if the wind is from the left. You're right about the dots. One difference is that on Forms B and C, the dot on the first figure has a little extra circle around it, and the line after the last figure is actually a double line. The arrows are not intended to specify the exact direction of a roll, although in some cases arrows shown next to each other, and in opposite directions, indicate that two closely-spaced rolls must be in opposite directions. That's it for now- I gotta do some work! Tom P. Remove | Alert Edit | Reply | Reply With Quote | Top
