<p>Doug,</p>

<p>You are correct. I just wanted to say that there is a maneuvers
called slow roll that is not mention in the IMAC rule book. I got the
description from the IAC web site. Here the description:</p>
<p> </p>
<font face="FranklinGothic-Heavy" size="2"></font>
<p align="left"><font face="FranklinGothic-Heavy" size="2"><strong>Slow
rolls </strong>have to be flown normally on a straight line (exception
is the avalanche). The roll rate has to be constant and the
longitudinal axis of the plane has to go straight. <strong>This
requires constantly changing rudder and elevator control inputs
throughout the roll. </strong></font></p>
<p align="left"><font face="FranklinGothic-Heavy" size="2"> </font></p>
<p><font face="FranklinGothic-Heavy" size="2"><font size="3">I wonder
how this maneuver is judged. Base on the description it is required to
use rudder and elevator. I suspect that the judge has the authority to
downgrade if the pilots is trying to avoid using rudder and elevator
during the roll. I really don't know how this is done in the real
planes but I will guess that a pilot will try to do slower roll rate to
get maximum points. Again, I could be wrong in my interpretation and I
am sure that you will know more details. </font></font></p>

IAC does have a "slow roll" in the glider catalog. As Doug said, the
traditional "slow roll" merely means a normal aileron roll without any
hesitations (points). Nothing in the description you quoted mentions a
particular roll rate, only that the rate must be constant.<br>
<br>
As far as control inputs go, if you want to see an IAC judge laughs
themselves unconscious tell them that you think a figure should be
downgraded because the pilot failed to use the rudder or what ever.<br>
<br>
In IAC and IMAC it does not matter how a pilot achieves the criteria,
all that matters is how well those criteria are met. Period.<br>
<br>
And Doug is right about the IAC roll rate. They will roll as fast as
the plane is capable of rolling. <br>
