Ali firewall thickness ?

[N.Smith]

Hi all

Today's odd question from me ... anyone know the thickness of ali used in
the old ali firewalls that used to be shipped with Rebel and Elite kits
before stainless was introduced ?

Just been asked by our PFA regulators for some reason (mine's stainless so
not sure what they're up to!)

Many thanks

Here's how I fly mine in the mountains (also this way in the flat lands if
conditions are right), when I am on a trip. This is with a 150 hp 0320
amphib Rebel. If I am going east, meaning there will likely be a good
tailwind up high, I will just keep it full throttle from take-off to descent
for landing. Of course this assumes no cloud ceilings. On climb out, I start
leaning around 5000 ASL. When I am around 8000, I am fully leaned out, and
keep adjusting it for best power and economy (I also have a fuel monitor and
engine 4 EGT/CHT monitor) as I keep climbing. Once I get over 10,000, I am
very much at the mercy of the updrafts and downdrafts, and hard to hold a
constant altitude. I try to keep to the east/west cruising altitudes, but
when you are going past peaks that reach 12,000, that isn't your primary
objective. It's not uncommon to be at 10,500 and 15 minutes later be at
12,000, then back down to 10,500 15 minutes after that. Bear in mind, that
you are supposed to carry oxygen if you are up there more than 1/2 hour.

Going west is an entirely different matter. Of course, before any cross
country flight, I get a weather briefing and take careful note of the winds
at different altitudes. But generally, I do an initial climb to fairly high
just to confirm the winds, and then just use general mountain flying
techniques to figure out where the best winds and lift are. The big
difference though, is that you don't go any higher than necessary, to avoid
the open head winds. It's sometimes surprising how you can find a tail wind
lower down in a valley when you would have a headwind up high.

If you google Mountain Flying, you will find some good books by Sparky
Imeson that I would highly recommend.

So with your 0360 Elite on wheels, I am quite sure that you will just be
limited by oxygen, not your airplane ceiling. But you should be able to get
some pretty decent cruise speeds up there, if you keep it WOT.

Builders and pilots,
Any body have a feel for what the expected operating ceiling of my
Elite is? I'm sure many of you out there get alot of practice around
those mountains. Around here it's just hills. I hope to travel out west
in the future so I need to learn some limits. Is there some sort of
procedure for climbing beyond say 10,000', like leaning during climb?
Thanks,
