throttle and RPM control

[adler_1]

P38

hello

1) when i accelerate the ATA reacts but the RPM gauge stays fixed at 3000 , i have a slider separate for the Prop RPM (bombers mainly) . How do i make the RPM react to my accelerator for example cruise 60 % would be 2500 , combat and emergency would be 3000 ? then how do i activate the supercharger for this plane ? tks

Turbo is automatic on the P-38.

There is a keybind to interlink throttle and RPM, can't remember what the default is, or if it works on the P-38. But the binding would be under your engine controls.

Interlink for throttle, RPM and Turbo works only for the P-47. P-38 does not have any linkage possibilities.

i cannot find any video which explains how to manage engine or supercharger , the learn to fly series does'nt say much . 

my big problem is the RPM is stuck at 3000 rpm and does not react to the accelerator , its a key issue but which one ? then how do i activate the turbo supercharger ? if automatic does it activate at 2800 combat ? i did a test all automatic in mission editor and the RPM does react correctly .

As Therion pointed out above, the interlink does not work on the P-38. I don't fly the P-38 often and haven't ever used the interlink elsewhere so I was not aware of that.

The turbocharger engages automatically to keep the MP high enough at higher altitudes. It is completely automatic, the only way you notice it is at higher altitudes, you will see your throttle response is a bit sluggish because it takes a bit of time for the turbochargers to spin up and help your engine to keep its MP up. 

 

This sounds like the same problem you were having with the Tempest. You need a separate key bind or axis for RPM, and you move that to adjust RPM. With the P-38 you need to make sure it is working on both engine, sometimes you will need to select the engines using the keybinding for that. 

Take a few screenshots of your engine settings so we can see how you are set up. It is very difficult for us to help without seeing if you are having a keybinding issue or just using the wrong commands. Increase/Decrease RPM is what will control the RPM lever. It can be an axis or a button for increasing and a button for decreasing.

Pitch control for RPM, throttle for manifold pressure.

1) throttle is fine 

2) Prop RPM is on slider 100%

3) Manifold pressure does react to accelerator

 

what doesnt work

Engine RPM is stuck at 3000 and does not react to increase decrease of accelerator

How do you regulate and assign pitch to fix this ? which key or keys ?

In automatic mode the engine RPM reacts correctly in tandem with acceleration .

The RPM is going to stay at Max RPM if you leave the slider at Max RPM, unless you reduce throttle enough that the propeller governor can't keep up. That's the whole point of the Constant Speed Propeller. You do not manually control propeller pitch, you control the RPM setting and the constant speed propeller automatically adjusts the propeller pitch to keep the RPM you set it to.

You seem to be used to the heavily automated Luftwaffe planes where everything is one lever. This will not be the case with the American or Soviet planes. If you want reduced RPM, reduce your RPM using the slider. If you leave the RPM at 100%, RPM will stay at maximum until your manifold pressure is so low that the governor cannot adjust propeller pitch enough to compensate and stay at the desired RPM.

So confirm for us: When you move the slider you have assigned to RPM, does the RPM lever move in-game, and do you see a reduction in RPM? If so, then everything is working as intended. If not, then we really, really, really need to see your keybindings to see what is going on. 

So just to walk your through this:

 

I want to take off in my plane. I set my RPM to maximum using the RPM axis, mixture to the auto-rich setting using mixture axis or buttons, and then I throttle up gradually with the throttle axis to maximum and then take off.

Later, I want to move to cruise settings. First, I reduce my throttle so that my MP is at the cruise setting. Then, I reduce my RPM until it is at the cruise setting. Now I am cruising.

When I want to go to combat settings, I increase my RPM to the combat setting, then increase my throttle so that the manifold pressure is at the combat setting. Now I am at my combat setting. 

I don't use tech tips, I use the guages in cockpit, so I can't tell you what percentage that is at, but if you have tech tips on it will tell you when you are on combat settings or cruise settings.

 

The rule of thumb in real life is, when throttling up, first adjust RPM and then adjust throttle. When throttling down, adjust throttle (MP) first, then RPM. In game this is not necessary, but in real life having high manifold pressure and low RPM could possibly damage some engines.

if that is the case then there is no problem at all , yes i fly only fully automated German aircraft online since ages and now just recently i have started flying Russian and  American . Yes if i reduce the prop rpm slider the RPM gauge reacts .So its a different ball game when flying allied planes , i use the accelerator  and monitor the ATA and adjust the prop for the RPM gauge setting to cruise and combat . Is that correct ? is there no way of combining between the prop rpm and accelerator  like in the game "assisted" but to use in manual online ?

There is no way to automate RPM and Throttle together, unless the plane allows the interlinking of RPM and Throttle, which only some of them do. If you are in an expert server, you will not be able to use the engine assist.

If you read the tech specs of the plane, it will tell you if you can interlink throttle and RPM and how that works.

With the P-47 for example, you can interlink the throttle and RPM when throttling up, but when throttling back it automatically decouples throttle from RPM - IRL this was to avoid accidentally decreasing RPM too much for the throttle setting. For the P-47, I recommend for beginners to just interlink the turbo and throttle together and leave the RPM separate. That way you can basically ignore the turbo except at very high altitudes where the turbo begins to overspeed, where you will rarely find yourself in this game.
