Mine came with a free case, and two little earmuff thingys.  I don't
really know what they are for, since they don't seem to fit on the
peltor.  I don't know if one generally gets a free case or not, since
I also ordered another item which was backordered, and maybe they
included it like a ``courtesy coke'' or something.

What *are* those earmuff things for, anyway?

Yup, I've seen this with the PM1000 ICS.  They included instructions
on how to modify various PTT's to allow voice to get thru all the
time.  A teensy soldering job does it.  Send me mail if you need
specifics (which are at home right now).

Some of the PTT use a double pole switch that cuts off the mic
line in addition to not grounding the "key" line.  This is
needed in some situations...but darned few of them.  You can
modify your PTT, if the plugs are not molded on by jumpering the
mic line, which is the "ring" of the plug.  Connect it to the
ring of the jack.  Note - most Telex PTT-300 are wired with
the mic disconnected. On those PTT's there is a black wire that is
located in the jack shell (and insulated out of the way) that is
the mic line, unswitched.  Connect it to the ring (middle) connector,
and you're all set.  You can leave the white lead connected if you wish,
it goes to the switch and the mic lead again.

What's a good flight calculator that has RNAV, allowing you to enter
multiple waypoints?  I use to have a TI programmable with drop in rom
chips ('82) that had a navigation package.  This package allowed you
to define RNAV waypoints and store them.  Navigation was done using
the onboard VORs, providing the information manually to the calculator,
letting it then tell you position, speed, mh, time to next waypoint.

Is there anything simular available now?  I tried the Navtronic Explorer,
but this was rather week in its capablilities.  

Someone metioned the Flightmaster.  I don't see it from Sporty's.  What's
the price, where can it be obtained, and what are its uses?

What other products are out there?

The rotary knob frequency selection, in particular, is a wasted feature as 
it takes two hands to change frequencies this way, unless the radio is 
lying down or otherwise supported.  The (US-only?) National Weather Service 
frequencies are nice but not aviation-specific.

I checked with ICOM and found I can upgrade my current A20 frequency

I'm currently doing this.  (Whether the new chip includes NWS is a don't

Does anyone out there have the raw data for NACA airfoils
(or any others).  Data I need is Lift and Drag co-efficients for any
angle of attack.  I have a book with several NACA airfoils in it
(Abbott) but it contains only the graphs of this data and not the data
itself.  I need the data in a form that could be typed into a data file
or read into a program as a data file.  I would very much appreciate
this data as we are trying to compile a database of Cd/Cl vs. Angle of
attack for a large number of airfoils(not just NACA).  If you know of
someone who has this data or a way of getting it please mail me with the
info.

marv is the only way to go. his prices are reliably rock bottom. he's
located right next to myf, here in san diego. he's a real nice guy, and
a supporter of montgomery field and the politics.

i own 2 pairs of 7004. they are easily the best value in terms of
utility and noise attenuation. i mean, i've tried a pair of the active
noise cancelling headsets, and they are nice, but the difference didn't
seem that great from my peltors.

i just completed a cross country flight in a 152. i'm talking from the
east coast to the west coast. i flew 37 hours with my peltors. they
became a comfortable addition and they kept my ears warm to boot.

i cannot give a stronger endorsement. they have mondo cluck per buck.

I've had a Delcom 960 for around 18 months and it has given good
service listening to ATIS, VOLMET, various approach frequencies, all
from the ground. I haven't had any cause to need to transmit on it
other than for tests, so I can't vouch for the transmit clarity. The
receiver side seems pretty good. On the ground I can still pick up two
approach frequencies that are about 20 miles away from home - on a
good high pressure day you can even hear the planes on the ground too!

The thumbwheels are OK to use, but the last digit is done by a 4
position slide switch (.000, .025, .050, .075) which I find very
fiddley and I'm not always convinced of it's setting. I wonder
sometimes how this switch will wear after some years - we shall see!

My only comment is that in my personal opinion, headsets are not only
'nice', but if you want to KEEP your current level of hearing ability,
headsets are mandatory!!!

It's well known that constant exposure to the noise levels commonly
encountered in the commonly rented and owned light general aviation
aircraft WILL damage your hearing.  

At the very least, your ears will even load up with wax in an attempt to
protect them from these high noise levels.  After flying many hours in Viet
Nam, I noticed my hearing was deteriorating and went to the flight surgeon.
He flushed huge chunks of wax out of my ears while commenting how common
this was with fliers, cautioning me to use ear protection or headsets for
all future flights.

Good luck on your upcoming solo, and sorry I don't have a spare headset to
sell you.  Just make sure the one you buy has good noise isolation
abilities, and that you wear it!  By the way, my two headset brand
recommendations are David Clark and Peltor!

No, actually I referred to another instructor.  If DN likes his regular
instructor except for the pilotage issue, it would be sensible to use
another instructor for a few flights specifically to tune up the
deficient skills.

I wouldn't recommend that he do this with a non-CFI.  The PIC-passenger
will be in the right seat, and few non-CFIs can handle that situation as
safely and comfortably as a CFI.

Well, I did have "mic fright." (Still do, to a certain extent.)  When I
decided to work on it, I got book called Radio Communications for
Pilots (something like that, it's at home, and I am, at least for now,
at work) put out by TAB books.  I believe it's written by a
controller, but that could another book...

The great thing about it, is that it goes over just about every kind
of radio procedure you could run into.  The author talks about
controlled and uncontrolled fields, fields with FSS but no tower,
ARSA, TRSA and TCA procedures (as if I could get INTO the Boston TCA
with a fixed wing plane...), WHO you're talking to and WHAT they want
from your life.

Anyway, I found it a great reference.  It's actually where I learned
my radio technique for uncontrolled airports (I beat my instructor to
the punch, so to speak) since I fly out of a controlled field (i.e. I
had the opposite problem to what you have now.)


Oh, and about your question on clearance at controlled airfields.  Are
you talking about an ARSA field, or just an ordinary controlled field?

If it's an ARSA (or a TCA), it's ATIS-CLEARANCE-GROUND-TOWER-
DEPARTURE.  If it's just a controlled field (with ground and ATIS,)
it's just ATIS-GROUND-TOWER, since what you need Clearance Delivery
for is your clearance through the ARSA or the TCA.

You get your clearance to taxi from the ground controller, and you get
your clearance to take off from the tower controller, and you need
neither of those things until you're ready to do them.

...My friend has been taught that since he is flying at an non-towered
...airport, he doesn't have to really worry about looking for traffic or
...using any radios.  After all, it's not very busy, and the pilots flying
...the jump planes *sure* know what *they* are doing,
...
...He then described an incident the other day where his instructor had him
...back-taxi for another takeoff, but failed to see the airplane on short final.
...The student became a little alarmed, taxied off the runway onto the grass,
...and turned around to wait for the landing traffic.  The instructor still
...didn't see the problem and demanded to know why he had done this.
...Meanwhile, the landing airplane went around, probably alerted by his taxi
...gyrations.  He didn't give me the impression he was praised for his vigilence.
...
...Having learned at a fairly busy place (BED), I am left wondering if,
...outside the elite pedantic confines of rec.aviation, that sort of
...instruction could perhaps be the usual practice at non-towered fields.

Assuming that your friend related all this to you accurately, my
advice would be to tell him to:

  1.  run, do not walk, and get a different instructor, and

  2.  to conduct all future flying many, many miles away from
      wherever that first instructor happens to be flying (or
      taxi-ing for that matter).

I have yet to see a water tower in the LA basin (maybe I've been flying too
high?)
