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

[Crumpp]

The RAF training manual quote only mentions the use of boost control cut-out to obtain maximum permissible take-off boost.

That is true.

What does it have to do with the fact the system was used before 100 Octane was an issue?

If this is true, this renders the whole 100 octane debate obsolete as pilots would simply use the increased power if necessary independent of the used fuel.

Right. From the certificate we see that a higher boost above +6 1/2lbs was available using the system on 87 Octane.

We also have Operating Note instructions in the General Operating Notes that allow for its use.

I bet Dowding did see a large increase in motor failures.
