Ears popping, and potential painful reactions in some people are just
one reason good IRL pilots plan for a gradual descent. Another good
reason is to prevent "shock cooling", which happens when you pull the
throttle and dive with an air-cooled engine. The rapid cooling of the
outer parts, heads, mainfolds, etc. can cause cracking and pre-mature
engine failures.

I don't recall the GNS430 discussion.. and remember, I'm the guy who
remembers the fly backflip landings.

PS. I had the same reaction as Quilly, "Hey that's a good VC, I wonder if
it's a Dreamfleet". 🙂

Nice cockpit. Serious question, what is that display above the 430? And
what's the little gizmo with all the connectors that looks like an MP3
player? .... an MP3 player?

Even more serious question, why did Beech build that "swing arm yoke"... I
don't get why that's of any benefit.

In practice I have no idea 😛 In theory, however, your passengers should be
able to "handle" 32 feet/ second/ second until they reach terminal velocity
of around 10,500 feet per minute! They won't like this decent profile, but
they could handle it at least until the ground interferes *VEG*.

How do I know they can handle it? Think skydiving!

As a matter of fact, yes! Terminal velocity depends on wind resistance.
Wind resistance varies by the shape a skydiver makes, so the "belly flop"
position that most civilian skydivers use gives the most resistance, but if
you fall feet first your more aero-dynamic shape will decrease wind
resistance (thus increasing terminal velocity). I'm not saying military
jumpers use this position, just that terminal velocity is affected by
variables.

And, at high altitudes the thin air produces less resistance, so your
terminal velocity (in true airspeed) will be higher at higher elevations and
slows down as you descend (but I guess in KIAS it would be the same).
That's why I say a civilian skydiver would fall at different speed since a
military HALO jumper would be falling through thinner air. There was even
an Air Force Airman who was the first person to break the sound barrier
without being inside a vehicle when he jumped from a balloon. Don't
remember the details but he jumped from something like 60,000 or 80,000 ft.
wearing a pressure suit.

The pressure differences between 0 - 10k, and 10k - 30k feet aren't that
much different considering the pressure lapse rate lessens with altitude.
Pressure at sea level (ISA) is 1013 mb, 10k' is 700 mb and 30k' is 300 mb.
The greatest changes in pressure for a given altitude change occur at lower
altitudes. Which is why it's not safe to fly with blocked sinuses in an
unpressurised ac thinking "I wont go very high anyway".

Having said that, the risk of hypoxia and temperature effects are great at
high altitude.

Archived from groups: alt.games.microsoft.flight-sim (More info?)

yeah but you are not going to be going much above 10,000 in an unpresurrised
aircraft without O2 and jets that cruise at FL300 pressurise the cabin
equivalent to about 8000 feet

so when jets descend you in the cabin are really only going from about 8000
to airfield height which is going to be a lot slower than freefall

I made the mistake of trying to open a bottle of coke in a glider which took
off at about 1000 feet field elevation and tried to open it at 9000 feet :)
reminds me of watching my mates face when i put that empty bottle of coke
that i filled with air at 30 metres under water on the back of his scuba
tank, and as he neared the surface you can guess what the sound effects
were like, i dont think he got that brown stain out of his wet suit :) :)

Hi Varmit,

Speaks volumes for the addon folks, I reckon, mate - I had the same
first impression!

Can't wait to support Bill Leaming, and get the Eaglesoft Cirrus on
Monday.

The only thing that bothers me about PR's cockpit is that there are so
many switches, dials, and knobs for his wife +/or son to tangle with
inadvertently, in such a confined space.....

You know how it can be - wives will be wives, and kids will be kids, and
both for so many years!!

Having said that, I can't imagine any greater thrill, for both the Dad
and the son, than for them to have flights together in Dad's
plane......WOW!!!

Combine that eventually with a camera, for the son to get familiar with,
and we may eventually have another regular contributor to this group, if
we're lucky!

John Ward

I would guess it is meant as a compromise between a yoke and stick? The lack
of a right hand part gives a lot more room in that part of the cockpit to
use your right arm for the knobs. Do they offer a left handed version?

Actually, its what's called a "throw-over yoke".

You can switch it between the left seat and the right seat by pivoting it
around the tube which goes into the center of the panel...

Bless you dear Peter for not raising a set of millennium brats.

In our day (sounding like a codger) most children sat quietly without
bothering anybody. And, nobody had to hit us to make us behave, the parents
just had to give you "that look".

Today, a large percentage of American children are raised with some sort of
relaxed discipline method as if the parents are afraid their kids won't like
them if they are strict.

We've come a long way... In the 80s my friend with the Baron used to call
me, sometimes long distance, and ask me to turn on cable TV to give him a
radar report. He used to bitch that the FSS operators would reply,
"Thunderstorms?...I donno..", and he'd say to them "Why don't you guys just
get cable TV?"

Does on-board radar have any unique advantages over satellite-sourced
weather or can these units replace them?

My long term memory seems fairly intact. Enough so that I can remember
each of the paddles that reddened my butt in school each time I deserved
it. I never had to get counseling because of the *abuse*. But I did
learn to NOT do whatever it was that got me into trouble in the first
place. I think I turned out OK. :)

Yeah, I got the paddle one time. Breathtakingly painful... and very

Don't know for sure, but the principle remains true.

Hi,

You can definitely shock cool them. They use (among other engines) the
R-2800 which is the same as in the DC-6. My DC-6 flight manual says not
to reduce the MAP on descent more than 3" per minute.

Now I assume that the WWII fighters were a lot tougher on their engines
than that, but if you shock cool an engine really badly, you are risking
a blown cylinder or worse.

Hope this helps,

Tom Gibson

In an unpressurized plane about a 1000 fpm from 10,000 is about as
fast as you will want to descend unless everyone has very good sinuses
that are open and free. Any congestion at all and you will be in
pain. With plugged sinuses 3,000 feet is enough to shatter bone.

Most people would have been in pain at that point due to the drastic
reduction in pressure, not from the rapid descent.
At altitude you have about 10 to 20 seconds of consciouness with a
complete loss of pressure without supplemental Oxygen.

The people don't notice the lack of Oxygen. The sensitive ones notice
the drop in pressure.

Take a ride in the altitude chamber. They take you up, check you out
and blow the diaphram. Then you set there talking over the intercom
and writting your name. Nealy every one thinks they are doing one
great job until they see what they wrote and hear how they sounded.

In general, altitude sickness, or Oxygen depravation is like losing
your judgemental ability or getting drunk. You lose the ability to
recognize that there is anything wrong.

A few people suffer side effects shuch as nausia, gas (don't eat beans
before a chamber test<LOL>) but it's not funny as it can cause
unbelieveable pain and the equivelant of what divers call rapture of
the deep.
