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

[Crumpp]

"Will already" means that production engines built before March 1940 incorporated the modifications.

There is nothing in that technical bulletin that reads engines produced before March 1940 will have the modification.

Once again, if it was the standard fuel in service, the Operating Instructions would reflect that.

They would not continue to publish 87 Octane Operating limits with scant references to the ability to use 100 Octane. They would publish the 100 Octane limits and the 87 Octane would be a foot note or a supplemental instruction.

Where is the 100 Octane fuel at the airfields in March??

Some must have been at North Weald for 151 Sqn and 611 Sqn.

Some must have been at Drem for 111 Sqn.

Someone needs to learn how to read a chart. The 23,000 ton figure for Mar to May 1940 is in the centre of the chart and is a combined figure for 100 and 87 octane fuel.

Yes, just as the Total for 1st Yr. = 267 refers to 100 Octane and Other Grades.

611 Sqn

They were not using 100 Octane at least by the log entry posted in this thread.

combined figure for 100 and 87 octane fuel.

The footnotes would point that out.

Clearly, 87 Octane is the only aviation fuel available before June 1940.

Once again, this is reflected in the Operating Instructions as well.

If 100 grade was the standard, it would be the standard in the Operating Instructions.

The estimated paper is dated October 1940 not 1939.

Typo...I know the paper is October 1940.

Crumpp Says:

In October of 1940, the United Kingdom as just half the Strategic Reserve required of 800,000 tons.

We have yet to see the identity of these 16 fighter squadrons from you Eugene.
