TomParsons Certificates/Ratings/Crew Stations: 13. "RE: Primary or Sportsman?" 05-13-02, 19:16z  Rick- >In figure 5, the 1 1/4 turn spin, I assume the spin is a >normal, or upright spin, why is the vertical line drawn >dashed, or inverted? I hope someone smarter than me also answers this question, but I'll take a crack at it. I believe the line is dashed to indicate the change in G loading on the airplane/pilot between the level portion of the maneuver and the vertical portion. The catalog of figures shows the opposite thing with spins entered from inverted; i.e., dashed line on the level entry portion, and solid line on the vertical portion. >Also, can you please walk me through the second figure? Is >that a "pinched" Cuban 8? Is the radius at the top >supposed to be the same as the radius at the bottom of the >vertical? That figure is called a "reverse wedge" or "reverse shark's tooth". The figure starts with a 45 degree upline, with a roll to inverted, centered on the upline. Then there is a pull to a descending vertical line, followed by a pull out to level flight. There are three radii in the figure; on the initial "1/8th loop" up to 45, the "3/8th loop" over the top, and finally the "1/4 loop" pull out to level. Each of these radii can be different, and the notation does not mean to imply that these "corners" must be sharp! This figure is different from a reverse half cuban eight because you are expected to draw a definite vertical downline. Hope this helps! Tom P. Remove | Alert Edit | Reply | Reply With Quote | Top
