[NSRCA-discussion] Safety Proposal amended

Where do you find this interpretation?

 "A disarm plug is NOT allowed to demonstrate a disconnect - there has to be a physical disconnect of the wiring and must be seen by an official." 

This was not the case for the 2011 WC. I participated in the TM meeting where it was initially stated that both battery leads would need to be disconnected. After some discussion the jury, ED & TD (me) determined that one lead was sufficient and it didn't matter if it was internal or external. Most of the E competitors made the connect / disconnect internally, often with the person doing it exposed to the prop arc. Models were also removed from the runway, so as not to impede the next competitor, before making the EoF disconnect (before returning to the pits). I was one of the officials watching for this.

If the quoted interpretation is official, then so be it - but I'd like to see the publication.

  With a passing vote of the NSRCA BoD, we respectfully submit to you the new Safety Proposal.  Essentially, the Safety Proposal that is currently with the AMA is being retracted and two new proposals put in its place.  The first one is simply the Fail-safe proposal that was part of the submitted Safety Proposal.  Then, the second new proposal will replace 6.9(a) as 6.9.1 and directly quoted and out of the current FAI Sporting Code.  The referred section is on page 16 in 5.1.11 of the FAI Sporting Code for 2012.  Please note that in FAI, in order to follow the rule, the disconnect must happen right after landing before the helper picks up the plane.  A disarm plug is NOT allowed to demonstrate a disconnect - there has to be a physical disconnect of the wiring and must be seen by an official.  Interesting huh!


  Before anyone says it, I disagree that the arming plug does not constitute a physical break in the wiring.  Through some consideration and advice from people that have run the Worlds, the plug is external and does not constitute proof that the physical connection internally has happened.  That's the FAI rule.  As submitted, that part is not written into the proposal.  It is simply the direct quote from the FAI Sporting Code.  Here is the exact verbiage of the new proposals as submitted to the AMA.  I don't know when AMA will get the physical proposals up on their site.


  New Proposal for 6.9


  6.9 – Propeller safety - All contestants using radio equipment with a failsafe function shall be able to demonstrate that propeller rotation will either stop or reduce to an idle RPM when the transmitter is powered down while the aircraft receiver system is powered on.  Idle RPM for this purpose is defined as an RPM during which the model will remain stationary when already motionless.


  New Proposal for 6.9.1


  6.9.1 – For electric powered models, the electric power circuit(s) must not be physically connected, before the starting time is begun and must be physically disconnected immediately after landing.
