Fact or Fiction?

Someone asked me about an interesting bit of trivia:

"Alaska has more airplanes than there are licensed pilots, the implication
being that many people in Alaska fly airplanes who don’t bother with
licenses."

Anybody care to comment on the truth or fiction of this comment?

ATC 610 Simulator

A friend in North Carolina is looking for an ATC-610 simulator to buy.
Does anyone out there have one?

A/C maintenence

Can a pilot replace his own airplane’s battery
without running afoul of the FAA?

ASRS experience

    Anybody have any experience with the ASRS (Aviation Saftey Reporting
System) forms? How did the immunity thing work out? Sounds like a get out of
jail free card. The forms and info can be downloaded at (Adobe Acrobat needed
for the form)  http://www-afo.arc.nasa.gov/ASRS/Overview.html   .

    "The ASRS collects, analyzes, and responds to voluntarily submitted
aviation safety incident reports in order to lessen the likelihood of aviation
accidents."
    " All submissions are voluntary. The FAA offers ASRS reporters further
guarantees and incentives to report. It has committed itself not to use ASRS
information against reporters in enforcement actions. It has also chosen to
waivevfines and penalties, subject to certain limitations, for unintentional
violations of federal aviation statutes and regulations which are reported to
ASRS. The FAA’s initiation, and continued support of the ASRS program and its
willingness to waive penalties in qualifying cases is a measure of the
value it places on the safety information gathered, and the products made
possible, through incident reporting to the ASRS."

Re: Oxygen Generators

Oxygen generators are chemical canisters which when activated will
provide oxgen to thre or four masks for about 12 mintes once
activated.

Once activated they cannot be shut off and the actual canister gets
very hot.

I have over 5000 hours on DC-9s and none of those aircraft had oxygen
generators. I can only assume that in this case they were a retrofit.

infant seats

Is it a law that infants must be in an approved car seat to fly in
general aviation aircraft? I mean, on the commercial airlines they don’t
have to be–parents can just hold them. What about in small planes?

LAPTOPS IN ALT OF 18000 FT

Hi!

Somebody asked me about reliability of laptops in a cockpit. He has
planned to make a trip within a group of 23 one and 2 -mots from europe
to alaska and back again (20000 nm, 65 hrs). Flight altitudes about 18000  
ft. The cabins are mostly not pressure tight!
As assistance for the IFR calculations (wind -> endurance…) they like to
use a laptop.

Now following questions arise:

1. Are the hard disks pressure tight at a p.alt. of about half of msl?
   Is it possible that the air pressure in the hard disk decreases and
   forces a head crash?
2. Is there the possibility of damage in the electronic chips due to
   cosmic radiation or is data failure "only" the worst case?
3. Do you know pc-programs (windows, dos), you would (not) recommend for
   a trip as mentioned above?
   Are there actual maps available as sw?

Thanks for your comments in advance!

maneuvering speed vs gross weight

A flight instructor told me that the maneuvering speed of an airplane
decreases if you fly less than max gross weight.  After some thought,
this seems wrong to me, and I’m interested in getting some opinions
and/or hard facts!  :-)

Maneuvering speed is the top speed where the wings will stall before any
structural damage will occur if the wing suddenly is rotated to a high
angle of attack.  Now, the maximum amount of lift the wings can generate
at a given speed is the same no matter what the gross weight of the
aircraft. And so, if the airplane is lighter, the wing lift can
accelerate the airplane up faster (f=ma), and hence the plane "pulls more
g’s".

I think this is the crux of the argument that you have to fly slower if
under max gross – you don’t want to "pull too many g’s".

The problem I have with this is that acceleration (g’s) don’t break
aircraft, force does.  Think of an airplane as two masses – a
wing and a fuselage – with some kind of structure holding them together.  
Then, if the you lighten the aircraft below max gross by making the
fuselage lighter, then the forces in the connecting structure are LESS when
wings generate maximum lift, even though you pull more g’s.  (Details
available upon request).

By this reasoning, maneuvering speed ought to INCREASE if you fly less
than max gross.  What’s the deal?
