P38 engine extremes

[adler_1]

Is it safe to fly full emergency for 5 mn and then reduce to full combat for another 15 mn  therefore a full 20mn at max engine capacity without risking serious damage to engine ? Auto rich is full 100% mixture , what is the best mixture setting for max performance when lower than 2000mt , 600mt  and deck height ?

Mixture 70% is auto rich, which will give best performance at all altitudes.

Mixture 100% is full rich, use it only when automatic mixture control is damaged.

Mixture 30% is auto weak for economic flying.

Mixture 0% is used to shit down the engine.

You cant use 5min of emegancy and then full 15 min of combat like you could on for xample late 109s because 5min of emergancy eat your combat time, so you can use only 10 min of combat insted 15 if you fly 5min on emegancy.

Also to fully recharg that 5min you need to fly 15min, so its for 1min of use it takes 3min to recharg that 1min so you can use it again, its not like on late 109s where its for 1min you take 1min, so you can fly 10min emergancy then 10min combat and 10min emergancy as while you flew combat you got recharged, on 51 and 38 you will be able to fly 5min emergancy then 10min of combat and then you waisted all your combat and need to fly continous 45min to fully recharg your combat first no mather it would take 5more min to recharg emergancy as you cant use it before your combat you waisted recharges... its stupid but thats how it works in this flying game, and on top there is BUG with techchat message that warns you when timer run out, or got recharged , as it works only when instrument panel option is turned on but as most players are axis in this game and timer controls are easy for axis airplanes and anything on american airplanes is crapp as hell in this game even this simple bug that would help american airplane players as they have most complex timers is not fixed still.

Conclusion youll have hard time getting max out of engine timers on american airplanes, and best is to just avoid them and fly airplanes that work like axis or RAF or VVS... game is trying to make it like americans didnt know how to design engines, guns or anything for their pilots.

so the P38's buzzing around attacking ground objects then lift and go into defensive or attack mode when countering an enemy fighter are flying all the time only in combat mode but with no extra weights such as ordnance since its already released ? when they fly back to base and i chase them in my D9 i see we have the same top speed being not more than 550 kmh half or less tank . How much later can you use the combat mode again after exhausting it the first time ? the 15mn limit starts no matter how much more power you add ? say i want to go back to base at 50% off combat with RPM at 2800 can i do that for 10mn ? usually the grids are a minute each so 4-6 grids are enough to get back if the enemy is around . My problem is going back at cruise continous can be hair raising some times .

I just use 48%, it is where you stop making a smoke trail. It is IIRC at lamda 0.9, gives you plenty power. All you need to look out for is engine temp, but in the Lightning I find that it is not an issue.

what does  IIRC at Lamda 0.9 mean ?

Lambda 0.9 is about at the top of the power curve, before the mixture turn too very rich and less efficient for cooling purposes.

 

[adler_1]

therefore correct mixture at 3000 RPM and MP at 54 gives you the maximum power without damaging the engine for 15 mn  and avoid the use of emergency . Does that mean return to base  must reduce the mixture below 48% ?

Any other mixture would be dangerous, as you'd have that huge Curtiss-Electric prop cut a swath through your rear end.

Wait, it's 3 minutes to recharge any given time amount? I thought it was 1:1 or 2:1! So if I climb for 10 minutes on combat, the 38 needs 30 minutes at continuous to recover? That's ridiculous. Do all Allied aircraft require 3 minutes of continuous per minute of combat? (Also, does emergency recharge on combat, or do all higher settings only recharge at continuous?)

 

Also, what's the 47's time limit when using water injection? Is it still 5 minutes, or can you go for 15? Does it eat away at combat/emergency like other allied aircraft, or does it recharge combat while on boosted, like other aircraft with water injection?

[adler_1]

we have 15mn to attack , defend and use the rest to return to base , so if we have to reduce to cruise continuous on a long journey back and bounced its game over .
