In flight recorder

"Lou" wrote

Ok, Ok, I was just thinking the worst possible ending of a flight.
The
safe was to protect the recorder from fire.

So I watch too much tv.

IF things did go really badly, and you WERE killed in a crash, I don't think
I would want the survivors in my family to have a tape of my last flight,
and dieing words and painful screaming.

If it did go badly, let there be no record of the end; only memories of the
good times. That is just me, though.

Thats perfect. It's a long way off, but when I finish my plane I
thought it would be cool to
record the first flights.

P.S., the safe was incase of disaster.



I have no problem with the idea of a recorder in the cockpit. I just see no
use for the safe.

Has anyone ever made their own in-flight recorder? I'm curious how
this would be done. I don't think it would be that difficult if you
use a regular cassette in one of those small fire safes. Just
drill a small hole to accomadate the mic wire. But how would you hook
it up to the intercom?
Or would you have a small lapel mic attatched to your headset? Anyway,
has anyone tried this?

I just bought a 72 digital recorder from Radio Shack for $69, weighs about
2.5 ounces and half the size of the old micro cassettes.

Seems very unlikely you would need fire proofing, but if so:

Grab some 1/2" or 1" thick ceramic fiber blanket from a local industral
gasket company. Use it to wrap or bag the recorder somehow. A bank bag lined
with the fiber and a plastic bag inside it, to keep the recorder out of the
fiber might do.

You could probably do it all for less than a pound.

My understanding is that fire safes are designed to protect documents.
They are lined with a chemical which produces water when it is heated,
which stops documents from lighting on fire. Water probably won't do
a lot of good for electronics.

Lining produces water? Where did you hear that poppycock?

They insulate, plain and simple, to keep the document below ignition
temperature.

I use that technique on all my dual flights and give to the student
for review. A couple of years ago I wrote it up as an article and sent
it to AOPA Flight Training magazine, but they did not seem very
interested. Here is a copy:

small recorder in our pockets. It worked really well at catching
everything that was said through the intercom.

It's not a "fireproof" solution, but hopefully this might get you
thinking in other areas.

Nice Article , Wish I had read it as a ppl student. I'm going to use
this technique for my IR rating

I hooked up a video camera to the intercom. I made up a special cable
with a potentiometer in it to attenuate the level coming out of the
intercom - it was massively too high for the camera's audio input, and
that worked fine (the proper way to do it would probably be an impedance
matching transformer).

Good article, why did you stop with AOPA?
There are other aviation publications.
