Lets see, Yet in the graphic, pg 16, it says "tactical air arm in England".

Officially 72" was the max but that is not to say 75" was not used unofficially.

RAF Mustang IVs used 25lb boost. Mustang IV = P-51D

So the 9th AF must have been based in GB because it is along way from Italy to the Normandy beaches. There was 2 FGs equipped with P-51s in the 9th AF, the 354th and 363rd.

Table 88- AIRPLANES ON HAND IN THEATERS VS GERMANY, BY TYPE AND PRINCIPAL MODEL: JUN 1942 TO AUG 1945 is a better source. P-51 1616/4844 (1st line) x 100 = 33.6%. Wrong, wrong, wrong. The G-10s were new production. There was only 15 K-4s and no G-10s built in Sept 1944. There was 1649 G-5s, G-6s and G-14s built in Sept 1944 tho. Fw190 production was 1391. 15/(15+1649+1391) x 100 = 0.49% of production. K-4s 15/1610 x 100 = 0.93% in Sept 1944 The 314 number Kurfurst posted was for Jan 1945. Considering the serviceability rate of Luftwaffe fighters at that time, maybe 200 were operationally ready.

Should be no problem if it was a 25lb boost Merlin running at 18lb boost.;)

High boost (1.98ata) K-4s were a very small blip in history only appearing, maybe, in the last few weeks of the war in Europe. What does June 1943 have to do with late 1944?:cry:

Reference source required.

You forgot about the re-engined Mk XVI which takes care of those IXs sent to the SU. PK312-PL499 - 800 last a/c delivered 30-6-44 (1st half of 1944) NH series, 600 delivered by June 1944 Your own research has: December 1943 Mk IXs: RAF : No. 19, 32, 43, 64, 65, 66, 72, 74, 93, 111, 131, 132, 152, 165, 222 , 237, 241, 249, 602, 682. Total : 20 Squadrons. Allied : No. 302, 306, 308, 310, 312, 315, 326, 341, 350. Total: 9 Squadrons Commonwealth : No. 401, 411, 412, 421, Total: 4 Squadrons RAAF : No. 451, 453, 457. Total: 3 Squadrons RNZAF : No. 485, 501. Total: 3 Squadrons. Grand total : 39 Sqn x 20 (not 12 as you stated) = 780 Granted all would not be LF XIs. You can go on all you want about total production of K-4s and D-9s but, End Nov 366 D-9s produced End Nov 529 K-4s produced only 236 K-4s were 'on hand' in operational units in the late Fall/Autumn of 1944.

And when the engine went to 25lb boost from 18lb boost, the engine still had a 5 minute limit.:music_whistling:

MH434 was delivered to 222 Squadron 13 August 1943. to 84GSU 15 June 1944 to ROS 7 July 1944 MH434 was built to the 9th Spitfire order of which the last a/c of that order was delivered to 46MU 29 April 1944.

I think some are under the misconception that those 1000 American bombers had 800 fighters as escort all the time.

Is this a confirmation that the Spitfire IX we will be getting is an early Mark? Oh well, another early 1944 Allied airplane to 'fly' against late 1944 Luftwaffe airplanes.

What does a Mk V have to do with the Mk IX? Note that it was 5 minutes for both the 18lb boost and the 25lb boost Merlin engine.:shocking: There was NO source given for the graphic posted in Post #813.

Messer pilots made their engines smoke ** as an escape tactic. Made it look like the a/c was hit and going down and the attacking pilot would break off the attack. ** heavy application of repeated on/off throttle. Doesn't sound like what is being described tho.

Be careful what you wish for Kurfurst. Daimler-Benz DB 605: "... I should point out the enormous problems caused by the unreliability of our supercharged Daimler-Benz 605 AS engines. They would barely make it beyond the fateful 50 hour mark. We were astonished to read in 'Interavia' that the Russians had complained to the Americans that the engines that had been supplied had a life of only 300 hours instead of the 350 hours promised! In my Staffel, it was frequently the case that engines would have to be changed two or three times before finding one which ran satisfactorily ..." - Karl Mitterdorfer, JG 300

The bold text can be ignored as the manufacture defects of the Fw190D-9 and Bf109K-4 are not modeled. Start up and warm up should get rid of any water/contaminants.

For some reason "secure an adequate margin" was not highlighted in (iii).:sly: There are no reference sources given from where the documentation posted came from either.

I am not the one who posted the links.:smilewink::music_whistling:

From the link provided. To eliminate the need for users to set H&T, PM Soldiers Weapons is developing two versions of the M2 machine gun: a "quick-change" barrel, to be fielded in April 2010, and a lightweight variant (half of the current M2 weight) which will augment the M2 with a fielding date of 2012. Does not jive with the graphic posted. 12 Describe the Slow method of fire on the M2 .50 Cal. Slow fire consists of less than 40 rounds per minute, in bursts of five to seven rounds, fired at 10- to 15-second intervals. 13 Describe the Rapid method of fire on the M2 .50 Cal. Rapid fire consists of more than 40 rounds per minute, fired in bursts of five to seven rounds, at 5- to 10-second intervals.

What Kurfy failed to mention was the DB605 was running a much higher CR than the Merlin. Merlin 6:1 DB605 8.5/8.3:1 with C3

Is that graphic for flaps/landing gear up or down?

Just because the Harvard/Texan is called trainer doesn't mean it was easy to fly. It was an advanced trainer that prepared future fighter pilots for more powerful a/c. http://www.vintagewings.ca/VintageNews/Stories/tabid/116/articleType/ArticleView/articleId/251/How-Not-to-Fly-a-Harvard.aspx

The Spit was easier to fly than the Harvard which had some quirks that killed many budding pilots.
