Blenheim operating limits and checklists

[Sammi79]

Engine temps are behind your right shoulder above the fuel cocks. I find engine temp is critical in the Blenheim, keep it above 200 and below 275. Max rpm I don't know but I try not to go above 2500ish.

Nicely hidden! thanks!

Does Blenheim have the one-stage compressor modelled at all?
Seems impossible now to climb above 5-6k feet now.

Compared to Accu-sims P-47, the Cod engines are not any near realistic at temperatures.
Can even make a runway takeoff (no taxiing), without using cowlings.

Actually, taking off with the cowl flaps closed is recommended in the pilot's notes for the Blenheim Mk.IV, they are supposed to be effective enough in terms of airflow getting through the engine once you start moving.

I'm sorry for pushing this back guys (i've been spending some time on other real life stuff lately and other aspects of the sim), i will try to finalize my copying of the relevant manual pieces and post it here sometime within the next couple of weeks

AFAIK the Engine head temperatures (asuming engine temps are sylinder head temps), arent they also depending on fuel mix, and not just airflow/rpm?
Is it modelled in this game/sim?
Shouldn't setting correct mix, also increase rpm slightly, like in RoF?

AFAIK it has only auto rich and auto lean mixture setting...

The P-47 has, not sure the Blenheim has, was just using the P-47 as reference, because it too has a aircooled radial engine.

Correct. In the Blenheim the levers move all the way (like a gradual, fully manual mix system) but they only have two functions: anything forward of the middle of the lever's movement range is auto lean and anything from the middle and back is auto rich.

This is not a glitch with CoD, the Mk.IV pilot's operating handbook describes how the real aircraft uses such a system.
