Inaccurate performance data for BOB fighters in COD comparing to RL data

[Crumpp]

The figures up to May are combined 87/100 octane figures which is why they are in the centre, a junior school student could work that one out.

Just like the 1938 figure is combined. Really? I highly doubt it.

If 100 Octane was on the airfields in significant amounts, it would reflect on that document.

It does not and you can read the Operating Notes to see that 87 Octane is the most common fuel in June 1940.

What 1938 figure? You can doubt all you like, provide some evidence that this meant there was no 100 Octane fuel available.

It is quite clear that in May 1940 Hurricanes of the BEF in France were using 100 Octane fuel. Starting 7 May 1940 we have 660,056 gallons, 2111 tons of 100 octane in France: this was before the balloon went up:
















Note too that there is another grade of fuel mentioned in the second to last document D.T.D.224 (77 Octane) which was used in light aircraft "Trinidad Leaseholds Limited" the documents on fuel consumption say "Other Grades" meaning 87 Octane fuel wasn't the only other type of fuel being used.

You continue to fail to mention that 87 Octane was being used by heavy bombers and flying boats in June 1940.

You have not yet accounted for 52,000 tons of 100 Octane being used by 16 squadrons between July and October, in spite of being asked several times.

You have not provided any documentation showing proof of the logistical arrangements the RAF used to ensure only 16 squadrons ran on 100 Octane for "intensive operational trials".

While you're asking others to post the August 1940 Pilot's Notes how about you post the relevant information requested for your "June 1940" notes, viz: front cover, inner front cover, fly leaves showing date and the A.P1590B you insist is inserted? You can still scan and you don't need a PC to post them.
