| Subject: | Smallest possible slip-ball ? |
Hi all,
My building partner is looking for a really small footprint slip-ball
for his panel.
To this date he only found something 65x29 mm (2.56" x 1.14").
Anyone around has a suggestion as to a possible source for a smaller
slip-ball ?
Thanks in advance,

"Failure indications" are not normal
operations . . . and yes, crew are
sometimes advised to pull breakers
for duration of flight as response to
a failure; implementing Plan-B for
comfortable termination of flight.
But I'm curious as to the design of
any ignition system that is not effectively
shut down by simply turning it off.
Was the pulling of a breaker intended
to 'reset' the failure or was the
breaker pulled to prevent a malfunctioning
ignition from causing more mischief
even tho it was commanded OFF by normal
positioning of controls?
I'm aware of no electronic ignition
system offered to the OBAM aviation
market that would require such an
action . . . setting the panel control
to OFF does what the label implies.
Do you recall what make/model of ignition
system suggested this procedure? Was
it to 'reset' the light or simply
disable the system for duration
of the flight?

If he has an artificial horizon in his panel then perhaps he can
piggy-back a slip ball onto that?
Something like this:

Rob,
Thank you for responding.
Interesting device to mount on the horizon.
Unfortunately my buddy has no artificial horizon, and he insists on
mounting his slip ball in the middle of his annunciator panel, hence the
search for as small a part as possible.
Thanks all the same,

The plane is a Twin Commander with TPE 331-10s. The specific failure is t
he 50% speed switch. There are 4 or 5 operational items that happened at th
at time. If any one of them fail the ignition indication will remain on.
Resetting the breaker will reset all of the thing that happen at 50%. Inte
restingly enough this procedure was "Tribal Knowledge" on my model, the nex
t model the procedure was documented in the POH.

Bob,
Have you ever commented on these little guys. They are resettable breakers that
fit into an ATC slot.
http://tinyurl.com/n4fem4d
I used fuses in my first build and also in my second build. I have looked at these
as a natural fit for alternator field power.

OK - I give up.
I cannot find the meaning of "OBAM" anywhere, but I see it used
frequently in this list. What does it mean?
Thank you.

I don't think that inclinometer necessarily HAS to be installed on the
artificial horizon - it would just require two tiny screws to mount
anywhere on the panel. Unlikely you'll find anything smaller.

I coined the phrase many moons ago after
having worked decades with one foot in
TC aircraft, the other in 'experimental'
aircraft.
While 'experimental' is the official
designation for giving a builder something
that amounts to a permanent, unbounded
ferry permit, I thought the term inadequate
and misleading. While we are indeed free to
EVOLVE our aircraft, the vast majority of what
gets licensed every year is anything but
and experiment.
The OBAM aircraft industry has at least
met and perhaps surpassed the quality,
utility and reliability of the TC
aircraft. I am loath to debase our
craft with a term that does not comport
with reality.
