wep on RAF planes awol???? boost levels??? no 100 octane fuel:(

Spitfire mkI, can't seem to activate wep (push through the gate), 6 1/4lbs max.

Spitfire mkIa same.

Spitfire mkIIa can use wep (push through the gate) goes up to 8lbs boost.

both Hurris, 6 1/4lbs boost max, no wep.

take it theres no 100 octane fuel for the raf since these are the 87 octane boost levels

somebody tell me i'm doing something wrong please.

I think you should carry on just as you are mein junge...

i guess you do, lol.

seriously though, major face palm.....

To add to this... the Spitfire mkIa has a bugged Prop pitch...

it shares the same Rotol constant speed unit but acts like the deHaviland 2-pitch... it only goes full fine-full coarse...

it SHOULD act the same as the mkIIa.

whats the deal Maddox Games... you trying to trick us?

this is definitely a bug.. the mkIs started getting fitted with Rotol constant speed propellers in July of 1940.

no BF109E1/E4 for Luft, no 100 octane fuel for RAF.

its Battle of Britain, but not as we know it, at least according to history.

100 octane fuel went to the front line units from spring 1940....

In all honesty though I'm as confused about the content choices made as you are.
I wonder what new content they plan to bring to the playing field once the performance patches are out of the way.

100 octane fuel should be relatively easy to do; a proper E4 would need 3D work.

@ Biggs
What does the other Mk I have?
Maybe the plan was to give one fixed pitch, one two pitch and one CSP?

Actually, I did some research on the 12lb boost Hurricane back last year for my squadron and the question of the 100 octane fuel arose. Here's Britain's stockpile of 100 octane fuel and my comments about it...

31st March 1940: 220,000 tons
11th July 1940: 343,000 tons
10th October 1940: 424,000 tons

"Now the stock levels are interesting and you can read them in a number of ways. You can say either that Britain and it's squadrons were well equipped with the fuel or you could say that Britain was well equipped but held back the fuel.
The way I see it is that those squadrons operating in France and 11 Group would of been well stocked with 100 octane fuel. Those that were in 13 Group would of been less so."

something seems off... I can climb in a mkIIa @2k ft/min on 4lb boost with my prop set at 2500rpm with a speed of ~230 IAS....

If I take the mkIa (with its bugged prop) and try a climb angle of 2k ft/min with my boost set at 4 and my prop set at coarse making the revs about 2300/2400 rpm i can only manage about 180 IAS.... and thats only for a short peroid of time.. after a few thousand feet ur boost drops to 0 and u cant maintain the 2k climb angle...u can barely maintain 1k!

and also with the mkIa at 18k feet with the boost at 4lb and the prop set at coarse I only manage to hit 240 IAS thats hardly 200 MPH TAS!

how is it possible to reach the planes actual top speed (which is 350 mph IIRC)?

Salute

Both the Spitfire I and Hurricane I were cleared to use +12 boost with 100 octane fuel on March 20th 1940. By that point, 100 octane fuel was in supply.

As it turned out, aviation spirit was to prove no worry for the R.A.F. By July 11th, 1940, the day after the Battle of Britain opened, stocks of 100 octane petrol used in the Merlin engine stood at 343,000 tons. On October 10th, twenty-one days before the battle closed, and after 22,000 tons had been issued, stocks had risen to 424,000 tons. With other grades of aviation spirit total stock available on October 10th, 1940, was 666,000 tons. Oil reserves were 34,000 tons.

Most of the benefit of 100 octane fuel in the Hurri I and Spit I was at lower altitudes, there was no gain above the rated alt of these planes. Only when the Spit II appeared with a higher boost supercharger at high alt, was there any gain up high.

Thanks for all the info Buzzsaw
