<DIV><FONT face=Arial size=2>Earl... this is a post I was going to
send yesterday also. Kind of supports what your
saying.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Seems if it really was a good snap that the
airplane would naturally be slightly off track at the end of the snap from the
original heading. SO... in theory... if the airplane was right on track
after the snap then it must of been either 1) cheated on the entry or
exit or 2) not really snapped.</FONT></DIV>

<DIV><FONT face=Arial>Posted this as a reply yesterday but it got snagged as
too long with the ongoing thread attached - started a new
thread.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>

<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Don't think that'll work very well. Let's take the
analogy of a car moving in a straight line slowly - turn the steering
quickly and the car will turn - changing "track". Do the same thing at high
speed and the car will skid - track stays mostly the same and only attitude
changes. Entering a snap is similar - establish a "skid". In both cases
there will be a minimal departure from the original line until "traction" is
lost and the skid occurs. </FONT><FONT face=Arial>Consider that the
faster the pitch input the less AOA increase will be needed before rudder
application. This is where we get into trouble trying to define a "break"
into a snap, some visualize this as needing to be huge while, in reality, it
may only be a few degrees. </FONT></DIV>
<DIV> </DIV>
<DIV>Also - with regard to the departure from track before the "skid". F3A
rules require a "separation from the flight path" and AMA rules allow it
"track closely maintains the flight path". Numerous things will define the
amount of "separation" including rapidity of pitch / yaw, mass of
airplane, wing loading, etc. The separation may be a few inches to a couple
of feet and is not to be downgraded as long as the aircraft "closely
maintains" track. So - if the snap (skid) progresses more or less parallel
to but slightly offset (maybe in both pitch & yaw) it's not only OK, but
a pretty good indicator that the snap isn't an axial roll.</DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Use the description to think through set-up and
control inputs. Recognize that a properly done snap entry takes only a
fraction of a second (if you have time to see exactly what's going on you'll
be getting downgrades for track changes). With the proper set-up and
practice a snap entry can be perfect almost every time - that just leaves
the exit to deal with. Finish wings level and enjoy the 10!</FONT></DIV>
