[simpits-tech] Circuit Breakers

[Cris Harrison]

Jay --
you realy have to define fast..  is it seconds, milliseconds, microseconds,
or nanoseconds....
lets start with the fastest..
nanoseconds TTL (gates switch at 2-5 ns. (realy fast)
microseconds instruction time of a microprocessor.
milliseconds times fuses and circuit breakers pop (it has to heat up)
seconds oh i wish i had a 11 second 1/4mile car :)
so
in old semiconductor amps the joke was the finals blow faster than the
fuses!!
last thought..
most of what you have in the cockpit is SIMULATED! ie what do you have to
protect?
In my cockpit i have control heads which have micros in them and my whole
project is running on
message passing via Ethernet

A simulated crash is the ONLY crash you can walk away from...
