    ATA in Inches Hg

    If anyone is interested. I made some formulas some time ago. BBR = British Boost Rating in lbs per square inch GBR = German Boost Rating in ATA ABR = American Boost Rating in "HG GBR = (BBR/14,223327) + 1,033227 BBR = (14,223327*GBR) - 14,695949 GBR = ABR/28,958992 ABR =...

    Greatest military blunder of WWII

    Personally, I thinks Germany's biggest blunder is not a military one, but one of producing in too small numbers early in the war. Even the UK outproduced Germany by 1940. With Germany going into full scale war production no later than 1938 they might very well have defeated the USSR before the...

    WW2 Aircraft Gun Specifications

    As far as I know the remaining empty links in bombers were taken back to base with the bomber (Italian bombers even had special trays to collect these). Only in emergency (an engine taken out) would all excess weight be tossed overboard.

    WW2 Aircraft Gun Specifications

    I'm sorry but I was into CFS 1 some years ago. But by today standards the game is outdated. Furthermore I don't really like the modelled flight behaviour in the game. The Hurricane for instance practically never stalls and can be flown with max stick. Pulling back the stick completely on a Fw...

    What if the Allies only had one fighter during the war?

    You want to use a P40 for the USAAF and US Navy right up to the end of the war? A P-40 with two stage Merlin would problaby have a top speed of no more than 410 mph because of more drag relative to the P-51. I don't think range would be the only issue. Upgradability would be hard with regard to...

    What if the Allies only had one fighter during the war?

    I don't think the F6F would do very well against German fighters. The best top speed I could find is 390 mph (most tests show 375 to 380 mph), and the best initial climb rate is 3650 feet per minute (both at 5 minute military power and 11506 lb gross weight). At combat rating (30 minute...

    Fokker D.XXI in Dutch service

    Thanks from me as well. Then to think that our Dutch government at first didn't want it. I sure hope we are not going to make the same mistake again by not buying the F-35 Lightning 2.

    WW2 Aircraft Gun Specifications

    I don't have load values. But on my website you can find values for Cartridge Power according to a formula designed by Tony Williams and a formula designed by me. The CP values are deliberately multiplied by a factor of 3 because I calculated them for correct DP values in CFS1. CFS1...

    The Effectivness of 8 x.303s

    I have two questions for HoHun. 1) How exactly can a Bf 109 E-4 pilot hit the target with the MG FF/M's and miss it with MG 17's? Do the MG 17's fire over the target? (Too high?) 2) In the Bf 109 C-3 the MG FF projectiles have better ballistics than the MG 17's. The MG 17's projectiles...

    Question on M.S.406

    To answer Rousseau's question, my best guess is either on of these two: 1) The MS 406 is the older design. So perhaps in the other designs new developments also led to an improved oil cooler design. 2) The MS 406 has a semi retractable radiator. It is not unlikely that the oil cooler was...

    Question on M.S.406

    I have to agree with Vincenzo. The first P-40's went into service in early 1941 in the DAF (desert airforce) and only saw operational service in the USAAF in July 1942. It's main opponents were Bf 109 F and G and Fw 190's.

    Question on M.S.406

    I wonder why the MS 406 had a semi retractable radiator. Was it supposed to boost speed under certain conditions?

    Ivan1GFP, are you looking for info for Microsoft's Combat Flight Simulator 1? Things like dp values?

    4 bladed 109?

    There are more strange looking 109's: With a Pratt Withney Twin-Wasp SC-G (1200 HP): With a BMW 801: With a V-tail:

    4 bladed 109?

    The Bf 109 K14 had a 4 blade prop.
