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

Exactly. It specifies the four types of plugs which may be used for 100 Octane. You would have to look the spark plugs authorized for 87 Octane and see if any of them match the part numbers.

I actually have to put the certificate that comes with a set of plugs in the logbook of the aircraft we work on and sign it. It is a required entry and the certificate must state the plugs are authorized to use in the aircraft.

Aircraft maintenace is very tightly controlled by convention.

Ok, so if you were running a spitfire with 100 oct would you have to change the plugs drain the tanks, clean out the fuel pipes etc before putting 87 in it?

What I'd like to know is, once the engine was converted was that it.. Did it stay as a 100 oct only engine? Earlier in the thread there were comments to the effect that they used both fuel types in the same machines. I find this hard to believe.

It's an important point because if it's a big job to change fuels then surely it makes no operational sense to switch, that also would mean that if a spit landed at an airfield other than it's own( a common occurrence during BoB) and they didn't have 100 octane then that's one machine out of action.

Logically this makes no sense. You'd only convert if you were confident that it wouldn't impact on operations. This is speculation on my part, just a thought bubble really.
