Bf109F-4 Engine Controls

[6./ZG26_Klaus_Mann]

I need help keeping the F-4 nice and cool. I try not to use Wep (1.4 at 2700) for more than 30 seconds at a time. I tried cruising at 1.2 and 1.3 ata and it overheats even with radiators completely open. I need help getting it to cruise properly.

[SeriousFox]

I never use 1.4 except for takeoff. Try to stay below 1.3 ata all the time, never had a single engine failure.

[Pupo]

slightly OT but a new thread would be useless:

how do you switcfh radiators from auto to manual. i have mapped a key to the command : "automatic radiator controls" and it has no effect.

[=ILS=_ppph]

same, it feels like the radiator is just there for an eye-candy, I dont know how to switch to manual either. pls help.

[BM357_TinMan]

Seems like the auto-radiator on the F-4 is still not quite done.  If you don't mess with it, I think it works, but if you manually change the radiator, I don't think you can re-engage the auto-radiator and you have to control it manually from then on.

 

I may be wrong.  This is only my impression from a couple of flights where I messed with it using the HUD (the switch on the panel doesn't work)

Also, I think on the real plane, there was an indicator on the starboard wing that told you what position your radiator flaps where in.  It would be nice to have some kind of indication besides the HUD (for those of us that try to fly as "Full Real" as possible).

Technically not even for takeoff. 

[Karost]

I use  below  1.3   ATA  (79%)

I use max Power in short time

I try to cool engine when I have chance like  when  Zoom then reduce power 

Some time I get max speed by using trim stabilizer nose down batter then max power

[6./ZG26_5tuka]

Strange, my 109 tend to not overheat at all when cruising and climbing...

 

Try to engage manual radiator controlls and test it with expert settings to avoid auto management tricking you. Also max continues power setting is about 1.15 ata but 1.2 also works pretty well ingame.

 

1.3 ata is the climb and combat power setting limited to 30min use.

Manual radiator controls have a bug, devs say they hope for a fix in this weeks update, would not do any serious testing until then

Climb with 1.3, but not for too long.. I switch it down to 1.1/1.2 after I gained about 400m's in altitude.. then engage again.

Cruise with 1.1 or maybe 1.2 if you want to go fast.

 

The key is watching your RPM and oil/cooling temp.

 

If you learn to keep an eye on the instruments and maybe even LISTEN to the engine, you should be good to fly as long as your fuel tank permits!

(OH! and watch out, your engine might cool down too much as well, keep the temp above 40 degrees at all times.. I've had a couple of engine failures because of that..)

 

Happy flying!

Did anyone try them after the patch? They aren't working for me now and apart form the switch from auto to manual there's no animation whatsoever. Tried everything from cowl flaps to water and oil coolers, yet none oculd opened them.

 

Do I have to assign the coolers to key now? I hope this isn't the case as even my X52 runs out of spare buttons...

Manual control of oil radiators isn`t working for me, too. But the water radiators can be controlled manually. First you have to assign the function "Switch water radiators control mode manual/auto" to a key (I think that`s obvious   ).

Then, there is a bug in the "engine controls" menu. The functions "oil radiators: open shutters" and "oil radiators: close shutters" are there 2 times. The first pair with keys "RCtl+Equals"/"Rctl+Minus" is the control for the water radiators.

Thx ram, seems that it has to be key than... Before the patch it worked fine with axis bound water radiator controll (which is on one of my handy rotaries). Macht mich traurig, me sad

S!

 

 Oil radiator manual controls won't work on Bf109F and G as they were fully automated. Only in Emil you had to manually adjust oil cooler.

hello everyone,

 

I got a question here, how do you know your engine gets overheat, I try to check the water temperature on the right botom of the instrument panel, but it just goes to about 80C and stuck there even I set the throttle to 100% for long time, there is no warning till I toast the engine, 80C is not in the red range according to the gauge designated. So how can i know something wrong be for ruin the engine?

[JtD]

The engine gets damaged if you use more than ~1 minute of emergency or more than ~30 minutes of combat power. It's not a temperature problem, just a programmers decision. There's no chance for you to know that.

[III/JG2Gustav05]

Thank you, JtD. F4's engine will be damaged with over 30 sec running at 1.4 Ata without overheat, will same thing happen in real world? 

[von_Greiff]

....a kind of noob question I dare to ask: I always read 30min.. so is it constantly for 30min. or does the time kind of added together? Can s/o post the answer or pm me?? Thank you all!

No, it won't. It's not that simple in real life, you have no guarantee that the engine will not randomly break down, and it's also possible that you can run your fuel tank dry on high power settings, maybe even WEP. The engine had to complete a standard 5 minute test run at emergency power after major maintenance, so 1 minute was pretty safe. The limits implemented in game are time limits from outdated manuals of other aircraft, using a similar engine.

The time is added together and also appears to be recovering. So if you use 20 minutes of combat power, then fly for an hour on lower cruise settings and then use another 20 minutes of combat power, you should still be fine, even if you use 40 minutes in total. But you'll probably run into trouble if you only cruise for a five minute interval.
