[NSRCA-discussion] Emailing: Omega

George,

Do you really think that a knife edge loop is an advanced maneuver?  I like the geometry of this maneuver and your thoughts about proposing something different.  However the 1 1/2 snap on a looping knife edge really does put it into an FAI category.  

Keep in mind this maneuver may not be that difficult on a sim but factor in real life conditions and any kind of wind condition and this maneuver could be all over the place considering knife edge and the 1 1/2 snap.

  Obviously, the entry and exit radii require the same radial arc and should be no more complex to judge than the four 
  corners of a square loop.

  Eliminating the snap and a half at the top as suggested by Ramsey would relegate it to the status of an Advanced 
  maneuver. The difficulty of the KE loop is 90% in the bottom half, which is completely missing
  here and the snap is included to increase the difficulty factor by requiring the change to opposite rudder.

    No, that works for me as a flier, but a specific radius may be difficult to judge consistently. 

    I've felt for a long time that that the maneuvers in our sequences utilize three different radiuses full height and half and full height loops and small radiuses used in facetted loops such as triangle, hex, octagon and square. 

    I would not have a problem pulling a small radius sufficiently before center to intersect with a centered full size loop, the bottom of which if projected round would be at entrance or base line altitude, but again it may be hard to judge.

    My feeling here is that,..........if we now have maneuvers that make allowance for different roll rates, maybe we should 

    consider making an allowance for a maneuver with different, but specified radii. Especially if it offers up some thing new

    and a break with the status quo.

    It's probably too much to ask.......................

    George if it is to be flown with equal radiuses it looks considerably different than the attached drawing. An equal R drawing is attached here.

    In any case it would be interesting to fly.

    I've been thinking about this maneuver for quite a long time and thought I'd pass it along for consideration by the Sequence Proposal guys.

    It's meant to be a Masters level maneuver and while it contains no integrated rolling elements it has some challenging elements. It's a center

    maneuver like an M and requires a deft hand to present with symmetry and grace while still being a "safe type" execution maneuver, in that it's a

    looping maneuver performed AWAY from ground level from an upright position with an upright exit, so the pucker factor is minimized.

    It's called an Omega, which should be easily understood by it's apparent shape. Here's how it goes.  See what you think :

    We're approaching center flying from left to right. At a point before center, a distance equal to 1/4 the radius of the loop, the model pulls through

    a radius of 135 degrees to a 45 degree up line and immediately pushes into the arc of an outside loop which is flown to the nine O'Clock position

    where the model performs a 1/4 roll to knife edge and continues the radius of the loop to the 12 O'Clock position where the model performs a One

    and one-half snap and continuing the loop radius to the 3 O'Clock position where the model once again performs a 1/4 roll and immediately pushes

    to complete the remaining looping segment and completing the maneuver by pulling through a 135 degree radius to exit in upright level flight.

    There's nothing really hard here guys, but the maneuver does demand respectable concentration. Think of it as a strangely entered loop with a knife-

    edge loop across the top 180 degrees with a snap and a half avalanche at the top. Roll and snap direction are pilot's option.

    Don't be too quick to discount it. I've only done it on the Sim, but if I can do it, it should be cake for the Masters guys.
