Now I don't mean to moan but in real life a prop will stop working around 30,000ft because the air is so thin, but I was able to climb to 37,000ft in a Zero????

Was I wrong or the game??

I have to ask...

What in the world are you doing at 37K????

XtrmeJ · « **Reply #5 on:** April 08, 2004, 10:14:44 PM »

So you were that strato zeke I saw. If I remember correctly you augerd shortly after

lasersailor184 · « **Reply #6 on:** April 09, 2004, 08:20:46 AM »

I still have to do that sometime. I was wondering how fast I could get a P51 or something going straight down.

Many planes in AH seem to be a bit too good at high altitude. Take Spits for example, read combat reports from Spit pilots (spit Mk1 in this case) who said that when they were flying at 30k they had to have an extreemly high angle of attack to maintain altitude, this is something that doesn't exist in AH, all planes have a fairly low AoA even at extreem altitudes.

You were wrong. Props does in no way stop to work at or about 30,000 feet. The Ta152 and the P47's are good and nice proof of this.

The Ta152 had a cealing of just above 50,000 feet and it had its best speed (using GM1 boost) at 41,000 feet, that's 11k above your stated "max" altitude.

The P47 was also a terrific high alt plane with a cealing well above 30k.

The problem with high altitudes and prop planes is not the prop, it's the engine. At such extreem altitudes the air pressure is lower and thus the engine won't get as much air as should. This is where different boost systems come in, GM1 in the case of the Ta152.

The P47 had a ramjet effect that increased speed aswell I believe.

Wilbuz,

Keep in mind that a Spit I or Spit V is a totally different concern at altitude that a Spit IX or Spit XIV.

Many people in AH whine that the Spit IX performs too well at altitude because "everyone" knows that the Spitfire was a low altitude fighter. The fact is that the Merlin 61 powered Spitfire F.Mk IX had too high a critical altitude for it's high blower and comparitive tests against a captured Fw190A led directly to the creation of the Merlin 66 powered Spitfire LF.Mk IX with a lower critical altitude for it's high blower. The Merlin 61 Spit IX, the one in AH, has a critical altitude of about 27,000ft and coupled with it's relatively large wing area makes it one of the best high altitude fighters in AH.

The Griffon 65 powered Spitfire Mk XIV is simply, in game terms, a Merlin 61 Spitfire F.Mk IX on steroids.

Both of those fighters had service ceilings of 43,000ft.

One other note, the RAF defined service ceilings as the altitude ad which climb rate dropped below 500ft/minute. I don't know how other services defined it, but a service ceiling is not the same as an absolute ceiling.

Wilbus · « **Reply #10 on:** April 09, 2004, 07:14:00 PM »

Karnak, I know very well that a Spit I can't be compared to a IX.

The post I made above was from what I read in (I believe it was this book anyway) JG 26 diary. They had a small snip from what shot down Spitfire MK I pilot said, he was flying at 30k, VERY high AoA to keep the alt when he was shot down. He tought the attack came from behind but he later found out it was a Head on attack by a 109. He did not see the 109 because the nose attitude was so high.

And with that post I compare what the Spitfire Mk I in AH at 30k. Not the 9's or 14's, where ever did you get that idea?

Simple fact is that the Mk I in AH (or any other plane for that matter) does not have a high AoA even at max alt of what the plane is capable of reaching. It's fairly straight at the horizon slightly higher AoA, but in no ways the extreem AoA the spitfire pilots talked about.

I never said anything about the 9 or the 14.

Right there is where I got the idea. In AH "Spits" pretty much means the Mk IX primarily, and the others as well.

Sorry that I misread you.

Oh Dang! You're right, must have been a typo on my side, I really ment Spit Mk I's, not spits in general, sorry mate and thanks for correcting

Pei · « **Reply #13 on:** April 11, 2004, 01:34:57 AM »

Haven't tried it lately but you used to be able to get C47s and some other a/c to ridiculous alts (50-60k).

Well thanks for clearing that up for me guys. And the reason why I was that high up was i was looking for trouble in a H2H arena trying to get someone else up by flying around but no came and i'd all ready climbed to 17,000ft so thought I'd see how high i could get
