[NSRCA-discussion] unknowns

[J N Hiller]

Thanks guys that will make it a little easier.  I will then assume that the slash marks through the loop only indicate centering the rolling element.
It looked nice through 90 degrees of ark with a very slow rate but I only got one out of maybe a dozen attempts that looked decent.

Another of the differences between IMAC and pattern.  No roll rate is specified and no arc is specified.  The requirements are that the roll be in the arc and be centered at the top so most pilots do a fairly quick roll across the top of the loop.

This has been an informative discussion. I started trying to fly the Sportsman sequence yesterday. Maneuver #3 is an inside loop with a half roll over the top, exit inverted. This appears to be an integrated half roll through 90 degrees of arc. 
Am I reading this correctly? 
Is the maneuver flight detail spelled out somewhere that I could reference?
Thanks

Doug,
 
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:
 
Slow rolls 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. This requires constantly changing rudder and elevator control inputs throughout the roll. 
 
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.

Vince,

The "Slow Roll" in IAC does not equate to a pattern slow roll. The IAC 
Slow Roll is just a roll, and the term slow is used to differentiate it 
from a point roll or snap roll. In truth, the IAC slow roll is never 
flown at anything but maximum roll rate available.
