OK not to hijack this thread, but what you and Peter are saying about ELT's
has me confused. I assume the OP is talking about the standard,
been-around-for-twenty-years, 121.5 MHz ELT. How in the world would a
satellite orbiting thousands of miles above the earth pick up this signal,
let along get a fix on it? This is something I have never heard of.

dopler effect; the thing goes biiiiip biiiip biip bip then back to biip
biiip biiiip again :-) when it is at bip, you mark a line on the map
perpendicular to your path; repeat from a few different directions --
these satelites have polar orbits -- and you got a fix.

I just wrote a little bit hastily:

ok, it's a lousy explanation; but Doppler effect it is
(with two ps);

So, it's really that it goes "biiiiipp biiiipp biipp bipp then back to
biipp"?

Just trying to make sure we've got it straight here.

3- Regarding the ELT. While surfing the internet, not only didn't I
find the answer to this one, it only netted me more questions. This
pilot has a Piper Malibu airplane (the name is not specified in the
story because I'm really not interested in getting sued, but that's the
model I'm using).


Surf some Malibu ads to see if you can find out what type of ELT your
'plane' might have in it.

Did you see the '5 Minute Rule' for testing?

Good luck.

need to accomplish ... That airplane cannot be found before 24 hours or
it'll mess up the rest of the book.

ELTs also frequently fail to work.

4- What position does the ELT have to be at in flight, for it to go off
by itself when it needs to?

"Armed."

5- Here are the extra questions that came up when I was looking for the
answer to the previous one. I found a .wav file of what an ELT sounds
like when it goes off. Is that an audible noise? How long does it
last? That would drive my pilot batty if it goes on very long.

Your file probably is that of what you would hear on the radio on frequency
121.5. Some ELTs do have an audio feature which is intended to alert the pilot
if it is activated unintentionally. The one I had in my Maule could be
deactivated by removing the ELT from its holder.

"A Columbia 400 impacted a mountain ridge Monday around noon, 50 miles east
of its departure airport, San Diego's Gillespie field. The aircraft was
bound for Scottsdale. The event may mark the first fatal crash of a Columbia
aircraft. Three people plus one dog aboard the aircraft were killed. The
aircraft's emergency beacon was not active when the aircraft was found
Wednesday. Columbia aircraft sent an official release Wednesday

Some of the newer units do an electronic self-test with a time-delay
before transmitting the 406 signal. From the Artex 406-1
installation/maintenance manual:

1. Always perform the tests within the
first 5 minutes of the hour (UTC) as re-
quired by AC 43.13-1B, 12-21 & 12-22
Note 3. Be sure to notify any nearby
control tower of your intentions.

2. WARNING!
Do not allow test duration to exceed
5 seconds. The ELT will transmit a
406.025 MHz signal after the ELT is ac-
tive approximately 47 seconds, the satel -
lite system considers the transmission to
be a valid distress signal.

We had one that liked to activate itself shortly after giving the
'plane in question a bath. Typically got a phone call from the USAF
shortly thereafter (unless I called them first). When you're
transmitting the aircraft registration number and the last known
lat/long, makes it real easy for them to figure out who's making the
little "beep beep beep".
