[NSRCA-discussion] Questions for the judging experts

Tue Apr 4 18:51:42 AKDT 2017

Harry thanks this is very helpful and clears that one right up.  The recommendation from those attending the clinic was to see if there is a way to make AMA rules more consistent with FAI for definition of radius for entry radius, stall turn, and double I  deductions and maneuver descriptions and for these maneuvers, etc.  

A couple other question for the experts.  This question came from a pilot who got both a zero and a 5  from the two judges on a particular maneuver- vertical upline with half roll.  He hesitated in the half roll, essentially doing what appeared to be a 2 of 4.  One judge zero'd the other severely downgraded the maneuver.  If someone could point out the specific rule on that one, would appreciate.  One location I believe calls for 1 pt per 15 degrees (6 points off) the other could be interpreted as "wrong maneuver".    He did fly it with a hesitation (unintentional) so it technically stopped rolling momentarily at the 90 degree point, then proceeded to complete the other 90 degrees to complete the half roll (or 2 of 4 depending on judges interpretation).

Final question that came up was a pilot's plane got stuck in a rut during takeoff and the helper had to go out and move the plane.  He got zero'd by the judges since he called takeoff and the plan moved slightly then got stuck.  However he pointed out that the rules state an example of an engine restart upon failing on takeoff (for zeroing the takeoff) which does not apply to electric planes.  I believe the intent is zero if someone touches the plane after takeoff is called and before it becomes airborne, but pls clarify.  NOTE:  in many contests with rough grass fields a CD may elect to not score takeoff or allow for this situation if announced at the pilots meeting but apparently this did not happen at that particular contest.

I am reviewing my notes to see if there were other questions, but I think this is about it!

Thanks again,
Don

Hope this helps Don.

5B.8.4. LOOPS 
A loop must have by definition,a constant radius, and must be performed in the vertical plane throughout. Itis entered and exited by a well-defined line which, for a complete loop, ishorizontal. For a part-loop, however, such lines may be in any other plane offlight as required by the particular manoeuvre. 
Loops and part-loops within onemanoeuvre must have the same radius. 

Each occurrence of aslight difference in radius must downgrade the manoeuvre by 1 point, while moresevere deviations may downgrade it by 2 or 3 points for each occurrence. 

Theradius of the first loop or part-loop, determines the radii of subsequent loopsor part-loops within one manoeuvre. 
Every loop or part-loop must beperformed without interruption to the circular flight path. Every visiblesegmentation must be downgraded by 1 point. 
If the loop is not performedentirely in the vertical plane ie it drifts closer or further from the judges,minor drift must be downgraded by 1 point, while more severe drift must bedowngraded by several points. 
In three-, four-, six-, andeight-sided loops, the main criteria are that the loop must have the sides atthe same lengths/correct angles for the defined number of times, and allpart-loops must have the same radius.

Questions for the NSRCA judging experts for 2017:  

Is the correct answer for clearly seen significant flat spots, take 2 or 3 points off  (test question)?  Or, should the answer cite slide 42 of maneuver execution guide which shows 1 point per (as shown in the picture) significant flat spots for consistency in judging this defect?

Is the intent of the plane being inverted for reverse top hats for unknowns, but the new sequence has a knife edge at the bottom of the reverse top hat so its neither upright or inverted technically speaking?

Does the first radius define the rest of the radius segments in F3A maneuver? It does state that in FAI regulation rules for F3M, but I could not find any reference to this in section 5.B.8.4 for F3A.

Latest rules for F3A is February 2017.  By the way, check out the new FAI rules for drone racing that came out this week (unrelated, but organizations are certainly pulling international interest in that direction).

No comments or questions on the AMA test.  Appears straight forward.

Thanks in advance,
Don
