Distances

[Jim_Woodward at beaerospace.com]

Regarding distance, model size, velocity, maneuver size:  The larger 
fuselage style planes (Smaragd, Lazulite, Partner, Vivat, Eclipse), make 
it easier to fly close.  These type of fuselages allow the pilot to 
perform higher quality rolling elements at lower horizontal velocity's. 
Flying at lower horizontal velocity's give you plenty of time to fly a 
medium maneuver set over the poles or slightly further out - if you have 
the power setup correctly.  Select a prop and throttle curve combination 
that gets the right power setting at the stick position you fly most of 
the horizontal maneuvers.  The closer you fly, the easier it is to see and 
control the model.  Given the new designs, with the right power setup, it 
is probably easier than ever to fly between 150-175 meters without looking 
rushed.

A lot easier to speculate and postulate than execute! But this is a good 
discussion, anything that ensures accurate judging and good flying is good 
for the game.

Earl, seems like there are three ways to get the distance:1 Judge guessing 
based on experience/visibility,2 Setting someone off each of the box 
boundies at 180M, or 3 Measuring, in real time what it really is.
Most of the FAI judges are older,more experienced, may be able to guess 
accurately, but also eysight problems can creep in.Trying to see what is 
going on ,due to distance, really adds to the load of evaluating all the 
other things that are more "judgeable ".
Putting a couple folks out of the box like we do in pylon racing is fairly 
easy to do, logistically, and reporting wise. Would also need a "distance 
judge" seated with the others to provide them guidance on where the plane 
was.(hard to do real time). Could also be done post flight as an added 
downgrade column for each maneuver that is imposed across the board 
against the "judged" value, where the pilot violates the "distance box". 
Then there is the "hi-tech" answer of a "two distance judges" that have 
range finder lasers that track and report/record the distance out. Two to 
give added credibility/ consistency to what is "seen".ORRR-install a 
transponder in the planes that would automatically give you position data 
-related to the box "limits". I have no doubt that there is a tiny device 
/system that is capable of this already available somewhere.Then there 
would be no doubt on ALL box violations,only the "degree" of the 
violation.
This would require software to accommodate the "end of box " distances 
,versus centered distances, but that would not be too tough. Also could be 
more sophisticated to add triggers for "over distance" reporting only, 
recording of data in real time on a comparable judging form, or some form 
of input to the judges in real time (beeper) or post flight for added 
downgrades.
All this is somewhat academic, since it behooves the pilot to "present" to 
the judges his best , and observable performance, to get the best scores. But maybe helping the judges have a better/prcise observation data base 
might be a step forward to him getting more exactly "what he deserves".
Ain't this more fun than sitting out in the sun and baking, while trying 
to do the best you can to observe, evaluate, and score?
