The 10-30 microphone is a 'dynamic' type, and David Clark does offer an
upgrade kit to convert it over to the superior electret version.  That kit
retails for between (choke) $80 and $90.  The hum you are experiencing is
probaly being picked up from your overhead fluorescent lighting, since
there is no 50 Hz signal available from the headset... I assume your local
power is at 50Hz, powering your fluorescent lighting.  Finally, the
microphone problably has an open winding on the coil, try measuring it with
an ohm meter. In which case the only option is to replace the microphone
itself.

Sounds like an expensive collection of DC's, repair-wise.  Good Luck!

I used to work with the guys who STC'd the TKS system for the Bonanza and
Mooney 201, etc.  I didn't work on the project, we just worked in the same
building.  From what I heard, the reasons they didn't certify for
flight into known icing were 1) expense and 2) liability exposure.

The solution can be found in rec.aviation.answers, specifically Geoff's

your answer is longer than the quotes.  Summarize where necessary.  Delete

I think the only FBO at Kennedy is Total Aviation Services.
He should phone before arriving to make sure there will be parking space
and to arrange for fuel.

If you land or takeoff at JFK during its rush hour, which is 3pm-10pm,
there will be a surcharge of more than $100 (I forget the exact price).
The regular fees are $25 to land of takeoff for a plane your size,
and parking is $15/8 hours.

I haven't looked into this for a long time, so you should call
up (718) 995-9760 to get the latest information.

Spare me the high and mighty attitudes.  I actually asked the "groundhogs":

   Hi Folks:

   This came up on another bboard; I'd appreciate answers to the following:

   You're considering going flying in a small plane for a trip around the
   Bay Area, but are a little concerned that it isn't safe.  Would you be
   more comfortable with a senior pilot from United (i.e., a proficient
   747 pilot), or with a member of the U.S. aerobatics team (a proficient
   stunt pilot)?

   No need to justify your response; I'm just trying to take a poll of
   people who aren't part of the aviation community.

   Thanks!

19 people indicated a preference one way or the other.  The score?
Aerobatics pilot 14, United pilot 5.

The people responding who explained their answer seemed to believe
that the stunt pilot would be better at coping with emergencies, but
also might be a bit more likely to get into trouble in the first
place.  Both of those views strike me as eminently reasonable.

I have through a stroke of luck come across a collection of
David Clark H10-30 headsets in various stages of (dis)repair.

Unfortunately I don't have a tester handy to see what works on them.
The earphones are ok, I've got a signal gen. BUT, what exactly does
the microphone produce? I can see that it's a coil, so it's some
voltage, which I perhaps should be able to see on a CRO, right ?

Only I don't. Just scads of 50 Hz hum. Has anyone played with looking
at the output of one of these things before ?

The other thing is that in Geoff Pecks FAQ he mentions the H10-30 as
having an inferior mike. Is it possible to replace the mike with a better
one ? IE are the DC parts interchangable ?

Thanks for any help you can offer.

There are a number of equilateral triangle shaped airports in the midwest;
hard to have too much cross wind with that configuration.  And you don't have
to pay much for an airport architect...

Perhaps you saw one of these that has since been abandoned.

Wow!  No wonder I was having problems!  I've been trying to do it in a
*stiff* crosswind.  :-)  :-)

All silliness aside, shooting an IFR approach can be extremely
difficult.  Consider a plane covered by 1 inch of ice, partial panel,
trying to do an NDB approach in the rain at night.  Not so easy, huh?

Since I know how to land in xwind with a taildragger (never landed one
of those nose dragger things in my life :-), but do not as of yet have
the instrument rating, it appears to me that the IFR approach is far
more difficult.  Hopefully this will change with experience.

Academics, MDs, engineers, anyone....."ain't" always what you expect. 
When I ran an engineering group that fixed nuclear reactors for a
Pittsburgh based big time company (logo is Circle Bar W)....first time I
had a chance, I'd ask a new hire "what class thread is on that bolt?"  I
was always amazed how many degreed mechanical engineers couldn't answer
that question....didn't have a clue what I was talking about.  When
dealing with 2,000 psi systems containing tons of radioactive water,
nuts and bolts are important.

At the other end of the spectrum, I got my instrument instruction from a
layed  off truck driver who's hand shook from a nervous condition when
he wrote.  He was a saint, and a wonderful teacher.  Every almost
illegible line he wrote in my log book is cherished.

tha the scariest solo of all is that first instrument flight alone.

I'll second that.  (And even third it!)

I distinctly remember mine.  I was coming back from Truckee to the Bay Area
and had expected to have an uneventful VFR flight.  Well, guess what.
After picking up flight following, **poof**, I suddenly went into
instrument meteorological conditions.  No sweat, I thought.  Use those IFR
skills to get yourself out.  Well, mountain clouds are devious.  I tried
for a little while, and then informed Center of my predicament.  Fine, they
said, you really should have filed a flight plan while you were on the
ground, but cleared to ....

And off I went.  Naturally, my favorite nemesis, airframe icing, reared its
ugly head.  For the very first time.  I'd never seen it during training.
(I guess my ice magnets weren't working, or my instructor's anti-ice
magnets cancelled them out!)

After descending from the lofty altitudes required to cross the Sierra into
the Sacramento valley, I fully expected to pop out of the clouds.  No such
luck.  On and on I and the Archer went, alone in the wet stuff.
Fortunately, no longer the icy wet stuff.  And I thought "gee, it's always
worked with an instructor on board.  I _think_ I know where I am.  But what
if all of this is a big joke?  I could land in _Bakersfield_!  Gasp!  And I
wouldn't know until I got almost to the ground!  What an awful trick!"

Naturally, the flight ended uneventfully by breaking out as I approached
the Bay Area.  My faith in the system had been restored.

I could tell you about my first ILS at SFO in nasty bumpy actual, my first
ILS with a (gulp) _passenger_, which was to minimums in snow at Binghamton,
NY, ...  It's amazing how much of an impression those early instrument
flights make.  And how totally _alone_ one feels up there.

My flight instructor, who used to fly 747s for Pan Am, once told me that
in his opinion the most difficult thing about flying a 747 is remembering
to turn off the autothrottle after touchdown.  Otherwise, you'll go right off
the end of the runway at exactly 150 knots.
