One of th eapproved rule changes, required for the 2010 season is the
implementation of an inertia switch to shut down an electric fuel pump
in an upset condition. I think this is a greeat idea. BUt seems that
there may be some open issues with that, at least it seems that way to
me. One is what is the requirement for impact to trigger the switch? It
needs to be higher that the bump of a push car yet low enough to be
effective. Can a switch be placed in a control line of a relay or does
it need to be in the primary line? I can purchase one from Pegasus for
about 60 bucks that is for 10 - 12 g's and it is used in the circuit
course racing. But is that too much? Too little? And that begs the
question of where and to what the switch should be mounted. Chassis /
framework? Inside the cockpit area? Does it for some reason need to be
accessible to the safety crew? I suspect more questions could be asked
but this is enough for me now, lol. Have any of you chatted with club
officials as to what they might actually be looking for during tech
inspection?
Input is appreciated and no I wont bend over, lol...
