P51 Mustang over 30.000ft (not kidding)

I were testing perfomance in my FS, and i turned on the display flying tips, to the test i used the p51 cuz propelled aircraft looks cool

and then the following tip shows up: your fuel mixture is set incorrectly press CTRL+X to set it correctly, i pressed and i looked at my mixture % to see if it really works and it did, then i said to myself, lets try to get this baby high, really high

I already knew you can go higher by adjusting mixture but when i was noob i did not know what fuel mixture was for so i could only get the p51 to 5000ft without engine damage (unrealistic) I did some research about all type of plane engine, and then i found what was mixture for, let me explain: as you get up, less atmospheric air around you so lets say at 500ft you have 1.2atm and 1.2 fuel flow

as you get up atmospheric air so you need to keep it the same for example 10.000ft has 0.8, then you need to put 0.8 fuel flow this is for the prop engine, the jet engines is automatic so here is a pic and a short clip https://imgur.com/a/5iIHTkm

the results? you ask, well i reached about 37200ft because engine shutdown because of low manifold pressure, in the pic is a few seconds after engine shutdown

if you want to do the same here is some tips:

set elevator trim up as you go slower to reduce drag and get more speed,

use time speed up because this take some time

be ready for a lot of turbelence and strong winds come for many directions

Which P51?

The one in the sim is a specialist racing aircraft designed for low-level pylon racing and is missing the two-stage supercharger fitted to fighter-type aircraft.

Use at high altitude probably requires using ADI Water Injection, to enable the manifold pressure to be retained but it depends on the reality level, which you haven't told us about.

Use of the Learning Center in the sim is not to be missed with this aircraft as it's non-standard in many ways!

Try the A2A P-51. It's the most realistic, and I've had it to 48,000 feet. Service ceiling is around 42,000, so that last 6,000 takes a while.:)

The A2A P51 is far more realistic than just about any other P51 and successfully models the two-stage supercharger. Instructions for operation are in the very comprehensive manual.

Reading the A2A manuals should not be regarded as optional...

WOW the default p51 racer may not reach that much because well, its for races but very cool

very interesting thread. but why so high in altitude? the highest they went during the war was 25 to 30 thousand feet. the amount of fuel and oxen to go that high would not make it worth the attempt.

For me: curiosity, learning, and a sense of adventure.:)

I don't how much fuel they need, but oxen have never been known for their flying abilities. That I'm aware of anyway. Is there something you know about that we should??

I would think, though, that if you put a cork in the correct end the gas build up would eventually make them float. Maybe. They aren't the lightest critters in the world, after all!

I could just picture a P-51, with a team or two of oxen floating along in front of them, like Santa's sleigh and reindeer.

Great, now that mental image is stuck in my poor little pea-brain...

I wouldn't want to be UNDER either one, though, without an umbrella...

;) :D :rolleyes:

Have fun all!

I know I sure am :D

you know when I first read this post I could not figure out what you was talking about. then I looked at what I posted and realized I had made a spelling error. lol it's supposed to be oxygen not oxen lol

I know, and I'm sorry. Sometimes my internal smart-alec takes over.

hey no worries im the one that messed up. nd I got a giggle out of it any way. :)

oh ok well how well does she handle up that high? is it mushy or does she respond pretty well?

Mushy, just like near-stall flight at low altitudes.

ah ok. well that's cause she's over her max ceiling.

Actually, because she's AT her max ceiling, where stall speed and maximum attainable speed meet.

No it's not. The max ceiling for a WWII Mustang was beyond 41,900 Feet - which was its SERVICE ceiling, a very specific height at which the aircraft could still maintain a specific rate of climb - in this case 100 ft/min.

In practice, the operational ceiling would be close to this figure as there is little left to `operate` with when you can't maintain more than 100 ft/min climb rate, but NEVER less!

http://www.wwiiaircraftperformance.org/mustang/mustangtest.html

So operating above 30,000 ft was well within the real P-51D Mustangs capabilities, but the default FSX Mustang is NOT a `real` P-51D and the overboosted engine lacked a two stage Blower as it was a racing engine, for the low-level, pylon racing class.

A normal Mustang could clear 30,000 ft with ease, and often did as they climbed to provide top cover on bomber escort missions.

Absolutely correct, but CessnaFlyer was discussing handling at the altitude I reached in the A2A bird (actually the Civ Mustang), which was 48,000+, the MAX altitude (i.e: won't go any higher).

Actually, because she's AT her max ceiling, where stall speed and maximum attainable speed meet.

I believe that often referred to as the "coffin corner". The U2 and SR71 routinely cruise there. Very dangerous place to fly!

I wouldn't thinks airliners would cruise in the coffin corner. Waaaay to dangerous. But I may well be wrong about that.

Have fun!

Was he? I took it as a reply to the previous post #15. He needs to learn to quote the prior post he's referencing. My post simply corrected the mistaken assertion that 30,000 ft was in any way the `ceiling` for a Mustang.

well the P-51 that comes with FSX is crap. but the A2A one I have up to about 36,000 with no trouble at all.

The FSX one is a very specific interpretation of a pylon racer. High Altitude capability is not required.
