Some years ago _Road and Track_ magazine tested a Ferrari Superamerica that
lived in Bill Harrah's collection. The staff instrumented the car and took it
out into the Nevada desert. The car, with a 5 liter V12 engine, would do
something like 180 mph in fourth gear and only about 120 mph in fifth, but
fifth was something like a 1:2 overdrive and at 120 mph the engine was
spinning at about half redline - 3200 -3500 rpm. At that speed the fuel flow
meter indicated that the car was getting in the neighborhood of 35 mpg! Wanna
fly on the ground?

We are fortunate enough to have a magic carpet to use for vacations. Costs
are comparable if not better than driving (less motels). The major benefit
is that we spend more of the vacation BEING there instead of GETTING there.

Couple of points here:

First of all, the VOR does not emit 360 distinct "radials" - the signal
is an analog sine (redundant, I know) wave offset from a reference
sine wave according to the direction in which the directional antenna
is pointing.

The easiest way to see how the system works is to explain how the FIRST
VORs worked.  The very first VORs consisted of two antennas:

1.  An omni-directional antenna
2.  An extremely directional antenna rotated, on a platform, by an electric
    motor at 600 (I believe) RPM

The omni-direction antenna transmitted a reference sine wave all the time
and in all directions.  The rotating antenna transmitted an equivalent
sine wave, except that it was phase offset, relative to the reference sine
wave, according to where the antenna was pointed.  If the rotating antenna were
pointed right at magnetic north, both the omni-directional and rotating
antenna transmitted equal signals.  If it was pointed due south, the rotating
antenna's signal was 180 degrees out of phase with the omni-directional
antenna's signal.

Airborne equipment then only needs to do a few things to get a bearing
from the VOR:

1.  Receive the omni-directional reference signal and
2.  compare its phase to the directional signal at max amplitude.

The difference in phase is the bearing from the station.

BTW:  Each of the signals from a VOR is nominally 250 watts.

There are, actually, quite a few of the old "rotating antenna" VORs
still in the country.  Modern VORs rotate the signal electronically (doppler
VORs) but both types look the same to your VOR receiver.

Reading about people in high density altitude situations "feeling" like
they were too fast on final reminded me of another illusion.

I had the opportunity to go into a private strip downstate a few months
ago.  The strip was 1300'x10' and paved.  Yes, it was ten feet wide, although
there was smooth grass on either side of the pavement.

I set up for a short-field approach, naturally, maintaining about 55-60
KIAS on short final with 40 degrees of flaps.  Chopped the power just before
the threshold.

Crossing into the runway environment I was startled by the impression
of speed that I had.  My brain began telling me that I was MUCH too
fast while, at the same time, the stall warning was sounding.  In my peripheral
vision I could sense grass, trees, etc. just whipping by.  Very
confusing.

Unknown, but many reasons are possible/probable:

1) Not all aircraft were restored to flying condition (don't know).
2) Not all aircraft were currently airworthy. (maintenance?)
3) No available pilots (there aren't many).
4) Andrew not expected to be so fierce in that locale.
5) Belief that structures could withstand the winds.
6) Not all could be removed in time.

Lots of possibilities, but usually comes down to a combination of many.

On a recent trip to Oregon (Scappoose--1S4) from Camarillo, CA (CMA),
my girlfriend and I (and two passengers we picked up in Oakland [OAK])
made good use of the audio input to my SoftComm intercom.  I was
surprised at two things:

	o The sound quality of both the intercom and my headset (Peltor
	  7003).  The music source was an incredibly cheap (read: $10)
	  cassette player.

	o The music didn't distract me.  Since I hadn't tried flying
	  with music before, I was concerned about that possibility, so
	  I thought I would just experiment and see what happened.  I
	  was quite prepared to find that I simply couldn't fly
	  effectively (maintain traffic and instrument scan,
	  position/altitude awareness, etc.) with the music going, and
	  for the first 15 minutes, had one hand on the isolate switch
	  (figuratively).  But I didn't notice any degradation in my
	  flying, scanning (was finding traffic just fine, thank you)
	  or navigating, and was glad to have the background music.
	  Now if I could just figure out how to get Oakland Center to
	  shut up long enough for me to listen to a whole verse of a
	  song, I'd be happy.  :) :)

I wonder whether having a little background music doesn't actually
enhance safety.  The music certainly didn't have the lulling effect of
the engine droan.  Probably depends on the music, I guess...

By the way, if you do go to off on the mags during a check, pull the
power back towards idle before you switch back on, and you will avoid
the boom.

Not an expert but...

During taxi, the engine is producing relatively low power and temperatures,
so aggressive leaning (to stoichometric mixture) is generally not a problem.
Fuel metering systems are designed to put a significant excess of fuel
at FULL RICH to help cool the engine during periods of high power and
low airspeed, e.g. takeoff and climb.

Now don't take this to mean lean to sputter... use common sense.

Remember to enrichen for the runup.

   The same problem happened to my father in our 172RG.  He was
flying from Champaign, Il to Lake in the Hills (3CK), where the
aircraft is based, and became aware of the problem when reducing
power from cruise.  He simply flew a semi-fast pattern, and when 
he had the field made, he pulled the mixture and made a normal 
power off landing at fairly normal speed. As the airport only has
a CTAF, there were no ATC problems.  The airplane was towed by a 
ground vehicle and repaired without much difficulty.... for him, it
really wasn't a serious problem.  :)
