[Milsurplus] APN-1 and other toys

[Michael Tauson]

Hi, guys,

In a slight departure from the usual subject matter,
however in keeping with the discussion of air
navigation, I've got some questions.

I know the Norden bombsight was tied to the C-1
autopilot.  I also know that there was provision in
the APN-1 for connection to an autopilot.  Was it also
the C-1 or another flavor ... or did it matter?

Next, what indicator was used with the BC-733
localizer receiver & the ARN-5 glide slope receiver? 
Also, were they coupled to an autopilot?

Ah, the prime question is "Where am I going with all
this"?  I think I can conjure up the big pieces of a
C-1 (and maybe an A-5, though I'm not sure) autopilot
as well as the major components of a couple different
flux gate compasses.  APN-1 components are still
available as are the ILS receivers and most of their
associated parts.  The ADF won't be a problem since
I'm sure I can find all the important pieces for an
MN-26, BC-433 and/or ARN-6.  Likewise, a marker
receiver won't be a problem though the indicator(s)
may be.  On the other hand, I think I'll skip the
Norden for now; at about $1500 a pop for a
questionable one and well over that for one that
stands a chance of working, it's a bit outside my
league for now.

I'm having a bit of a problem with connectors, mounts
and the like (as well as the ILS indicator for the
BC-733/ARN-5 pair) but this is not unique to this
project as those who've built up their own
installations of other types will attest.

The end result wants to be a navigation set as would
be found in larger aircraft.  I'm not basing on any
particular model but rather going as generic as I can,
though I readily admit I'm probably taking some
liberties I shouldn't.  On the other hand, it'd be
cool to see how it all ties together.

Oh, yes.  Any clues where to find manuals on things
like autopilots?

BEst regards,

Michael, K3MXO
