I was originally thinking, yea, blinking lights might be more
of a problem than help, could be the FAA folks were thinking.
Then I went to work, started reading the spec's for some new
FAA software I am working on, and holy cow! talk about blinking.
It is their CHI (Computer Human Interface) spec, and they
got all kinds of stuff blinking, and at different rates! You
do a hand off from your sector to another sector, it blinks
the datablock at one rate. A flight is transitioning your sector
to an airport to land, but is controlled by another controller, the
datablock blinks at another rate. It seems everything has a
possible different rate (configurable software).
Then thinking about audio alerts. We had a controller tell us
about a cessna 337 that landed gear up a couple years ago. The
controller called 'em several times on the radio, "your gear
is up, go around". After they ground to a stop, the controller
got a chance to talk to the pilot, "didn't you hear me tell
you your gear is up?". "We couldn't hear nothing, there was
a loud buzzer going off".

--> AeroElectric-List message posted by: "Charlie Burton" <notrubce@hotmail.com>
I'm converting a single panel mounted Ray Allen trim switch to two stick mounted
hat switches. I realize I need a relay deck to convert the SPST stick switches
to DPDT but do I need to install two relay decks, one for each stick switch,
or can I simply joint the wires from each switch together before they connect
to the relay deck?

Yes. Its a stupid buzzer. If the light comes on the buzzer comes on too. I
turn the master ON - yell CLEAR - and turn the key to start. The EIS takes a
few seconds to boot up so no beep. I also have an "ice cube" relay in
paralell with the starter solonoid which disconnects all the electronics for
protection during the start. NC contacts rated at 40 amps. which restarts
the EIS at switch release. Its only a couple of seconds and then the EIS
senses 20 psi. oil pr. and stops or never starts the light and beep. Then I
turn ON the radios.
Works great

First, know that the "6-inch rule" is a hand-me-down from
the darkest ages of electrical systems installations in airplanes.
I recall statements at Cessna in 1964 that short wires tied to
the bus behind the breaker panel did not need to be protected
because they were less than 6" in length.
Now, where did that number come from? The folks who thought it
up are probably dead. Was there some careful consideration of
the amount of smoke one could expect from then popular nylon
over PVC wire? Hmmm . . . if tefzel smoke is more/less, unpleasant/
hazardous then perhaps the rule of thumb should be 4 inches/10 inches.
I'll bet we could get them to debate this for at least a couple of
years before generating a new rule.

Run a solid piece of wire for whatever length it takes to do the
job neatly and with good craftsmanship.

Good advice. At some point, you can't protect everything. The
probability of a wiring short is proportional to the number of
connections it makes, the number of corners it turns, the number of
adjacent wires in the bundle, and the vibration it is susceptible to.
I don't think length matters in this equation.
Murphy will get you, though... at some point you'll drop a wrench across
two terminals. I did this on a 200V battery pack for an electic
vehicle. It's a good way to cut steel and burst your eardrums in one
move.

If this is the pump I'm thinking of, the hi/lo power wires are taps
on a series wound motor. Tying them both together would get you
high speed and powering just the low speed wire would get you
low speed. The wiring for a 2-10 switch to power one wire at a time

Bob I think that drawing may be incorrect Should not #5 be jumped to #1
instead of #3.
While I have you how would you wire a pump on light to show pump on in both
high and low configurations. One Light on with either high or low? Thanks
