I agree with you Owen. The accident in question had a lot to do with the
ignition system. Old Murphy's law rules the rocket range. If anything can go
wrong, it will. There were a number of factors that lead up to the accident
such as poor ignition system and extra people in the area . I think the new
rules are attempting to eliminate any of these factors from happening again.

The change seems specifically targeted at what you can use to light a motor and
it makes sense. It seems to me that (although I would say it's still dangerous)
you are also still allowed to use those switches to activate recovery
pyrotechnics or anything else so long as it isn't lighting a motor.
It's a shame someone had to get injured to call attention to the hazards of
this type of ignition system, but, really, it is a dangerous way to light
motors and I think it's a good rule change.
OTOH, the updated spectator rule is unnecessary and I believe the existing
rules were adequate and had they been followed, there wouldn't be an issue with
"someone riding a bike that had no business being there just stopped by to see
what was happening".
Just my $0.02.

That is a good question. I would say that you could still use a breakwire for
timer activation. And in my opinion this is a more reliable method than the G
switch for what it's worth.

Would this include activation of avionics using a breakwire for low
speed/g-force launches, or just using breakwires for lighting motors?

Yes these are switches used to for launch detect to start a second stage.

I think a launch controller is a type of ignition system. They may
be referring to cluster and staging ignition? But yes, the TCC controller is
great as is...

I still haven’t read it all but either way our launch system does not use none

It references the switched in regards to motor ignition and seems to refer to
the launch controller:
2-12.6 A rocket motor shall not be ignited by any of the following:
a. A switch that uses mercury.
b. “Pull wires” that disconnect or complete a circuit.
c. “Pressure roller” switches
----
It does not make reference to av-bar arming switches.

Hey All I have attached the 2012 Tripoli sanctioned rules and we are a Tripoli
club so everyone needs to read them, print them carry them or however you want
to help enforce and use our newest rules, I will get time this week to really
study them but I noticed a couple of quick ones like
Section 2-18 Participation now reads in part:
"Non-HPR Fliers are allowed in the High Power Launch Area if escorted by
a HPR Flier. A HPR Flier may escort and be accompanied by not more than
two (2) non-HPR fliers in the High Power Launch Area. The HPR flier
escort is required to monitor the actions of the escorted non-HPR
fliers, and the escort is fully responsible for those actions and for
the safety of those escorted."
There are other changes. For example, the use of mercury switches, pull
wires, and roller switches have now been banned. This means there are
various products by different manufactures that can no longer be used
for air-starts.
I don’t want to due a review until I have had time to look the complete pages
over.
