I do, however, admire those who can manage to squeeze the trigger at the precise moment of convergence.  I believe they should be restricted to flying Gloster Gladiators.

Think you're sitting pretty in your Runstang, my man?

Just see how many perkies Karnak talks HiTech into slapping onto the Spit XIV to keep the "best plane of the war" in the game.....

Need some more info on that please.


Hi Wilbuz, Reference the time 109's had over London, this would seem to be an often reprted fact that is only partially true.

Early on in the Battle some 109 units were based on or near the Cherbourg peninsula, some 100 miles from England in a straight line, these 109's had a more limited time "over London" than the 109's based near Calais (just 20 miles from England).

Later on in the battle the Cherbourg area 109's were repositioned around Calais, this shortened the time they were over the Sea BUT.. Goerings orders to the fighters to stay near both bombers and 110's meant they escorted at inefficient throttle settings so had a shorter than ideal flight time.

109's were fitted with a red light when thier fuel was low, this was the indication to leave for home (France), at altitude a plane, of either side, could, and infrequently did, glide some of the way home.

Hope this helps, basically the 109's range (Time over London) depends where it takes off from.

I do think it is a very good idea to make sure the burn rate will match historical scenarios.  

The cherbourg penn. is by Guernsey right?  This appears to be about twice the distance from london, so I would suspect that gave the 109s a little less than 3x as much time over the target.  We are looking at 50 minutes of vulch time?  Does this seem to be historically accurate?  How lond did they launch from cherbourg compared to calais?  Did they keep using both?

Did a little testing on fuel burn last night, flying from Calais to London in a 109E with full fuel load and burn rate set to 1.0. I climbed out to 22K over the Channel.  I had used a little over 1/3 of my fuel upon arriving over London, leading me to think that 1.0 might be about right.  Anyone else done any testing on the Europe map?

At the start of the Battle LuftFlotte 3 was based in the west of France with 3 JG, roughly these were based at..
JG2 based @ Le Havre = 120 miles from English coast
JG27 based around Cherbourg= 70 miles from English coast
JG53 based around Brest & Rennes = 170 miles from English coast

In the middle of August A. Galland transfered all 3 of these JG to the Calais area to reduce thier flight times to England.

The range of the 109E-4 was 410 miles, the Spitfire was 395 miles, similar and around an hours flying time.

So the modifier for fuel that makes their flight times around that time would be the one to use.

I can't be more specific because pilot reports of the time mention "around an hour flights" This doesn't mention how much time is spent on cruise or full Mil power..  :confused:

Hope this helps

S! Sabre

If you have used only 1/3 of your fuel to get to London, then the fuel burn is too low.

Considering you had to climb to 22,000, using full throttle, it would only take you 1/6 of a tank to get home even if you used full throttle.

That leaves you with fully 1/2 a tank to fool around with over London, or about 30 minutes of flying at full throttle

Considering the 109`s had around 10 minutes air time over London historically, this figure is obviously generous.
