Dive tests found at Williams' site:
Fw-190 (early model)
Bf-109 (9.3 MB pdf, in German, but numbers should be self-explaining)

('Vw' = Wirkliche Geschwindlikheit = TAS; 'Va' should be IAS ; 'Machzahl = Mach number)

Many thanks, Mike al

added: dive limits for the Bf-109F - table - should have bearing on problems with wings of the Bf-109F

Speed limits for the Mosquito FB.VI:

Those are the post-war limits, 25 mph lower than the wartime equivalent. Will see if I can find my Aussie docco from December '44. I keep trawling around looking for a WWII pilot's notes, never can find any for the VI.

Found the Aussie doccos I was looking for re: wartime Mossie FB.VI dive speed limits.

Date on the first page, speeds (in IAS) on second two.

Edit - date is on the second of the three attachments, sorry.

Great work everyone. But this one is great, been chasing the mach limit of the Mossie for some time now. Not bad at all. Probably the best of any WW2 twin.

I think I also have another docco which gives the results for the Mossie of dive tests, expressed in mach number. This is different from the limits imposed in the pilot's notes, I suppose for obvious reasons.

From memory, the maximum test results were around 0.7 mach, or somewhere just north of that.

Again, it's "somewhere on my hard drive", will see if I can find it.

Found the mach number stuff.



I believe the note at the end about diving limits being 350kts is incorrect, post-war, as above, it seems to have been 370.

Great thread on fighter plane dive limits. How about the big bombers?
Anyone got the limits for the B-24, B-17?
