Zeke Posted December 29, 2014 Posted December 29, 2014 After reading about the K4 in the DCS manual and watching YouTube vids and reading whatever I can find on this form, I have a few questions regarding engine management. I can see in the vids that most of the guys driving those 109s are maxed out at 1.8 ATA and around 2800 rpms. According to the manual that would damage the engine shortly. I was trying to keep my ATA around 1.35 while practicing. I tried just maxing it out and didn't have any problems. Should we be concerned with keeping the ATA limited? What is more important to keep an eye on, RPM or ATA? I've read also that as long as the MW50 is on you don't have to worry about ATA? Love this flight model!!

As long as you use automatics you can use whatever you want as the ratings have linked ata/rpm settings. As you switch to manual you can control the rpm and boost separately but avoiding overboost and overrev.

jaydee Posted December 29, 2014 Posted December 29, 2014 (edited) As long as you use automatics you can use whatever you want as the ratings have linked ata/rpm settings. As you switch to manual you can control the rpm and boost separately but avoiding overboost and overrev. Good point yo-yo. I am certainly no expert but if I often Switch Planes(Auto/Manual PP),I have gotten into the habit of watching the Tacho most of all. My logic is If my engine is in the "Sweetspot", doestnt matter if Im Climbing Hard or Diving Hard,im getting the best from my engine . Nothing in the Cockpit gives me instant feedback from my engine like the RPM. Temps are valuable but Delayed. ATA really (to me) is just a Reference Point. Just my 2c worth. Hope it helps Zeke ~S~ Edited December 29, 2014 by jaydee Coulnd see OPs Name R7 7800X3d,64g 6000 Ram,4090, Pimax Crystal.
jaydee Posted December 29, 2014 Posted December 29, 2014 Somethin else I just thought of Zeke. If you concentrate on RPM and keeping your engine performing at its best. Eventually you will be able to fly without looking at RPM....You will just "Hear" the engine working as it should. you wont have to look down when you shouldnd be lookin down ! ~S~ R7 7800X3d,64g 6000 Ram,4090, Pimax Crystal.
Zeke Posted December 29, 2014 Author Posted December 29, 2014 Thanks for the input guys, I was just really confused after flying IL2 BOS so much. I was in the habit of really keeping an eye on my ATA so I didn't kill the engine.

Good, fast, cheap. Choose any two. Come let's eat grandpa! Use punctuation, save lives!
SlipBall Posted December 29, 2014 Posted December 29, 2014 I read some where that the pilots flew 109 by ATA, so as to conserve the engine life's
sobek Posted December 29, 2014 Posted December 29, 2014 I read some where that the pilots flew 109 by ATA, so as to conserve the engine life's If the controls work as they should, it doesn't matter which readout you go by, RPM or ATA as long as you stick to the operation limits. Both using ATA and RPM will give you similar engine life because both are linked and the limits are equivalent. Once you have a governor failure, you must start looking at both because an overrun of either of the two can dramatically damage the engine. Good, fast, cheap. Choose any two. Come let's eat grandpa!

SlipBall Posted December 29, 2014 Posted December 29, 2014 (edited) that's true but there was a ATA number they used when covering long distance's, I can't remember it though Edited December 29, 2014 by GT 5.0

SlipBall Posted December 29, 2014 Posted December 29, 2014 There's a RPM number for that too... yes, the article did not supply that, only the ATA
Grizzly1606688174 Posted December 29, 2014 Posted December 29, 2014 I've seen a documentary where a former wwII pilot says they never cared about ATA. Will post if I find. I imagine they just knew their plane by heart and sound or something.
jkeiltaylor Posted January 1, 2015 Posted January 1, 2015 The manual says, "Please note that, unlike in many Allied aircraft, the Manifold Pressure gauge is used to set power in the Bf 109K-4. The Tachometer merely provides feedback from the engine." What gauge shows the Manifold Pressure? Is it the same as the MW-50 gauge?

It's on the right side of the centre console about mid height. Literally on the next page in the manual, but referred to as the Supercharger Pressure Gauge. Fancy trying Star Citizen? Click here!

jkeiltaylor Posted January 1, 2015 Posted January 1, 2015 I'm still trying to understand all of this so I'm sorry if this is a noobish question...the manual labels that gauge as supercharger pressure. So because the supercharger is controlling the air pressure, it is also an indicator of manifold pressure?
SlipBall Posted January 1, 2015 Posted January 1, 2015 yes that is showing the engine manifold pressure, when supercharger is in use the pressure rises a bit more
Hadwell Posted January 1, 2015 Posted January 1, 2015 (edited) i believe the DB605 was rated at 1.42ATA, 2800RPM, but the original 605s(ones used in the G6s for example) had problems so they limited the max manifold pressure to 1.3 and MW50 was prohibited... and the manifold pressure gauge is right near the rpm gauge, right beside the propeller pitch gauge, and their all right beside the flare gun... you can basically ignore the supercharger gauge since the only way your supercharger would ever get damaged or not be working properly is if you get shot at and probly need to rtb or bail anyway, it's all automatic, and its not as if when you rtb, your crew chief is gonna have to fix it, you're gonna get a new, never been flown before, streight from the factory plane next time you spawn anyway... all that said, i usually stick around 2650rpm, 1.42ata, and when im in combat i switch the radator to fully open from automatic, unless im running, then i leave it on auto... more important than ata or rpm settings is that the automatic radator doesn't open the radiators fully when you're doing stall manuvers, and the engine will just die unless you open the rads fully yourself.

Zeke Posted January 2, 2015 Author Posted January 2, 2015 Ummmm, all this is interesting. Lately what I've been doing is leaving the rad to auto and just maxing out the engine at 2800 rpms and 1.8 ATA in combat. Haven't had any problems with the engine failing.
Hadwell Posted January 2, 2015 Posted January 2, 2015 try holding your nose streight up, hanging on the propeller as long as you can, with auto prop pitch on, and 1.42ATA, no throttling back... with auto rads, the engine will overheat right away and die, but if you open the rads fully...

No problems here after several attempts. Plane just noses over and no problems with the engine.

Davis0079 Posted January 2, 2015 Posted January 2, 2015 (edited) you manage your engine mainly by ATA (a measurement of "intake" manifold pressure)...rpm is a feedback....not an input....it is looked at as a reference as to how the engine is reacting to your ATA setting... radiators are adjusted according to speed, not engine settings.... automatic radiators and prop pitch are not fool proof, you can still damage your engine in auto prop or with auto rads ( the auto radiator runs off a thermostat, meaning they are reactive, not proactive)...pulling your nose vertical without opening rads will cause heat and by the time the thermostat try's to adjust the radiator position, its too late...not rocket science.... fly some of the earlier model 109s in other games and you will see the advancements that the K model has....giving you a clearer picture on how to use them to your advantage....
