God almighty!


H/H couldn't do this with the C**ntvergence?

I may need to consider this for the rig while being on the road. I never had any confidence with the Convergence and the X- vert couldn't handle any wind.

non-R/C question (for VaStinkyBarefootBoy)

On a typical flight - I understand cabin is pressurized to less than pressure at 0' ASL - what equivalent altitude is the cabin pressurized to?

At cruising altitudes of 30k-40k ft AMSL, passenger jet cabin pressure is equivalent to ~6000-8000 ft AMSL.

Are there any planes other than the 787 Dreamliner that have 6000 ft cabin pressure?

Not sure. I just know that passenger jet cabin pressure @ typical cruise altitudes is usually stated as being between 6k & 8k AMSL. Typically closer to 8k when cruising up near 40k.

Highest I've ever flown without an O2 mask or cabin pressure is 14k, in my dad's C185. The ol' naturally-aspirated Continental O-520 was working pretty hard up there.

Drove my '87 Buick GN up to 14.1k on the Mount Evans Scenic Byway, too. Thanks to the dinner-plate-size turbo, it didn't even breathe hard up there! Still had no trouble pulling 22 pounds of boost! But I was huffing & puffing a bit just walking around!

Most airliners are in that range. Pressurization to the equivalent of 8,000 ASL is the max allowable mandated by law.

The "Aircraft" section of this wiki page explains a bit more:

Are you going to do a float fly on that little pond in the corner?

Did two flights with the Jug on the way to work. Although my thumbs, brain, and plane weren’t in sync in the air, the takeoffs were nice and both landings greasy.

I don't think so, what I might do love the far side where there is no one at is take Little Tim be over there but Jesus the wind picks up immediately after sun up!

Well it seems I am a bit late to answer the pressurization question.
I could give you the exact schedule in the climb for the 737 but it maxes out at 8k.

We can’t be dispatched above 10k without pressurization (PACs inop - Press & Air Cond systems. We have two and can operate for a limited number flight segments with one inop.
Incase of loss of pressurization we descend to 14k immediately (unless in high mountainous terrain) then down to 10k.
O2 masks required until 10k.

Sorry I was late to the party. Thanks for answering everybody.

I gave away the little 1/12 RC truck to my wife’s 2nd cousins 11 year old only to find out Dad had just bought him a fairly nice 1/10 Arrma Granite 4wd truck. He seemed to like it though.

Oh well, no good deed goes unpunished :-)
