Optimizing flight/speed with CEM

[Blackdog_kt]

Try going to an external view (enable them in your difficulty settings if you need to) and making an attempt to identify the point from where the puffs originate.

I haven't spent much time in the RAF fighters except for some Hurricane sorties, but if you could tell us where the puffs of smoke appear on the airframe we might be able to give you a few more hints.

The effect you describe however is similar to a busted radiator: if you let the temps rise too much the pressure in the lines gets higher as well and it can break the pipes. When that happens, you can see white/grey puffs of steam coming out of the radiator.

Another thing which i'm not sure if its modeled in the sim is the escape valve. In the real world Spitfire there was an escape valve ahead and to the right of the windscreen, when the coolant would overheat some of it would be blown out of that valve to lessen the pressure and prevent damage to the pipes. This allowed pilots to "ride the overheat" so to speak for a small amount of time, at the expense of depleting their available coolant supply.

i got the hang of it like this:

take off:
fine pitch
radiator 50-70% (what takes not to reach 100ºC)
engine 20%
->fire engine
warm up (do your check list in the meantime)
->engine to 30-40% (start moving, watch the temps and adjust rads accordingly)
->if no engine stuttering: step on it

airborne
using your throttle (but not bellow 80%) and climb angle to keep the revs bellow 2800rpm, start a shallow climb until 1000m; go in steps if you have to; always trim to get just your intended angle; don't wait for the stall to interrupt the climb, anticipate that

once at 1000m trim for level flight, attain your max speed (by now i close my rad about to 70-80%, always watching)

climb to 2000m using same process

once at 2000m trim for level flight, attain your max speed

start a shallow dive and change to coarse; your revs should jump to near 2100rpm
->throttle to max; use the small speed gain of the dive to help the spinner pick up revs
once at 1600m you should have at least near 2300rpm which is by now a stable engine operation, that allows for an efficient rev pick up; at coarse pitch you must not fall bellow 2100rpm or you may need to go back to fine pitch

start a gentle climb as you should have enough speed for such
climb to 3000m
once at 3000m trim for level flight, attain your max speed; you should be hitting the 2500rpm soon which is the optimal situation you're seeking

if serious trouble persists, maybe i can drop a vid of it...
