Magnon, You have to be more careful with selecting Your sources and jumping from individual samples (ONE TEST on ONE engine at ONE given day) to general conclusions. Put them in a meaningful statistic in the first place would be my primary advise. This may allow the interested reader to judge whether or not the sample has significance for the whole Jumo-series or not. You may find the relevant primary sources in the Freiburg Archive (but it may be possible that some of the material relating to Jumo benchtest moved to Berlin since 2002) and I know that a roughly 2in thick agglomeration of single benchtests is there. That beeing said, I greatly appreciate Your input here.
The speed margin of wartime Me-262 (with all the plane to plane variation) and Meteor is significantly different from what You suggest. It´s not a single value but a spread of discrete points. For the Me-262 You may find the Rechlin mass tests on 142 serial Me-262A1 intersting. Tests were conducted late in 1944 with top speed measured in different altitudes and clacluclated back to standart atmosphere, but the paper dates to early 1945 (I think it was RG-Lunatic who digged out this source first in another -262 relevant post). It would be highly interesting to see a comparable convolution of serial Meteor-III tests before jumping to general statements.

It seems to me that there is arguably a parallel between the Shwalbe and the Starfighter, in that both
- were specialist interceptors
- lacked manoeuvrability
- had high wing loadings (the Starfighter much higher)
- suffered from instability in flight, particularly in high-G manouevres
- had relatively high stall speeds (the Starfighter was far worse)
- had very high attrition rates (the Starfighter's was in peacetime)
... [Interceptors] sacrifice performance in the air superiority fighter role (i.e., fighting enemy fighter aircraft) by tuning their performance for either fast climbs or high speeds, respectively. The result is that interceptors often look very impressive on paper, typically outrunning, outclimbing and outgunning less specialized fighter designs. Yet they tend to fare poorly in combat against those same "less capable" designs due to limited maneuverability... Interceptor aircraft - Wikipedia, the free encyclopedia
Where the analogy breaks down is that the Me 262 was built for speed, and was expected to have a clear superiority over its opposition in this area and hence be able to outrun them.
Interestingly, the Starfighter was designed in Kelly Johnson's "Skunkworks."
Do you know anything about it DragonDog?

Maybe this was why 1432 were built, most sitting on the ground and only around 300 were ever used in combat. (Sorry, I'm just being facetious here.)

I won't change the topic except to say your knowledge of the 104 is IMHO sorely lacking , it was a rare aircraft in the fact it had a 40 service career as a 1st line fighter,
Spitfire XIV. 900-odd built, 120 were ever present in service. Tempest ditto..
Bf 109K. 1700-odd built, highest number I know to be in service at time was 300-odd.
P-47D Thunderbolt... what, 15 000 built...? I willing to be there was never more than 1500-2000 in service at a time.
It's a typical ratio.
But back to the topic of Me 262. As you agreed there are few valid comparisons between the two fighters?
the unit was designed to kill US/RAF bombers not engage in a hand to hand struggle in the air with opposing fighters..............look how wide the turns were of the 262 allowing Allied fighters to close within and deal the lethal blows
What Erich the Old Sage is saying, DragonDog, is that the Me 262 was a specialist interceptor. That's what it was designed to do... That's what it had to do.
There is nothing shameful about that, surely?

Bada - one note on your comparison of Meteor vs Fw 190 speed limit at 20,000 ft. The table showed 400 IAS which is Indicated Air Speed not True Air Speed. The Fw would do 400mph TAS but closer to 280-300 (a guess - I don't have my books unpacked to do the math) IAS at 20,000 feet.
I'm sure it put the fear of God into any bomber commander who had to face it, but it wasn't a dogfighter, it was a specialist interceptor...

oupsie, my mistakeyou're right.
Magnon:
the 3-6% or whatever procents, are they calculated on the total number of airframes build?
otherwise, you have to know the total aiframes build till that day of 44 sorties, substract the airframes not delivered yet , the ones in maintenance ,the one destroyed and the ones in flight schools (not that there were a lot of them at the end of the war and specially for the 262). If we take the example of the spit14, so, let's take the date of 10jan44, there was only 1.65% availibility of the spit14.
BUT if you take in acccount the airframes awaiting for delivrey , the proto used for testing, you'll find that there was 100% assignation for the MK14, what means 8 airframes, and if we apply the 75% availibity rule, we end with 6 airframes capable of combat.
Now you see what i mean?
Men can tell the stats what men wants if you don't have a valid and comprehensive protocol to use.
it was never an interceptor in CAF livery in fact it was a very good strike fighter/including nukes, flying very lo its hard to hit what you can't see . I'll let you get back to your Quixote quest to validate the Meteors existenceI'm sure it put the fear of God into any bomber commander who had to face it, but it wasn't a dogfighter, it was a specialist interceptor...

OK then guys... The important thing is in bold type:

I will admit that I am not going to change your minds, but when people fail to learn from mistakes, they usually run a big risk of losing wars.
But that's OK...
