Cant use throttle on sovier planes, simplified engine management

[Tinku74]

Hello

 

I have the mapped to the Z-axis of my joystick. When I fly German aircraft, moving the slider increases or decreases RPM, and I can fly without any problems.

 

Same movement has no effect if I am sitting in  La-5, P-40, I-16 etc. In the La-5, moving slider will not move the throttle, but the small lever below the throttle does move. Strangely, if I turn engine off, and turn it back on, moving the slider will increase throttle. 

 

Anyone has any idea what I am doling wrong?

 

Thanks

Look in your settings and see what it's mapped as, change it to throttle if it's mapped as something else.

Hi,

 

not sure Iunderstand. Throttle is mapped to joystick z-axis, and works fine for Bf 109 and Fw-190. However when flying a soviet plane, I push thr throttle but get no power.

[Legioneod]

Not sure how thats possible, if the throttle works for Axis it should work for Allied.

Hi Tinku. By Simplified engine management I assume you mean you have ticked the green box saying "engine auto control" in difficulty settings which links rpm and mix to the throttle setting?

 

I fly with that unticked but I just went and checked, and when ticked my throttle control affects rpms and boost in a Yak just as it should, so the game itself should work.

 

When there are problems like this it is usually with your key bindings. Throttle control also has a default keyboard binding of -/= to reduce /increase throttle, so try that to see if it works in the game. If it does, go to settings/ketbindings/engine control and check your HOTAS axis binding, make sure it is not bound to anything else.

 

When you start a new mission I find that you often need to move the throttle (or any axis) through it's full range in order to get the game and HOTAS axis position aligned. So check you are doing that.

 

Last resort is to go to difficulty settings and untick everything. Then see if the throttle works: if it does tick the boxes one at a time and recheck each time. 

 

Good luck!

Sounds like you are playing with complex engine management on, which requires you to use the RPM lever as well as the throttle

[unreasonable]

Good point Jade_Monkey.

 

Tinku you should check out some of the tutorial videos too: try this on one the Yak, which explains engine management.

I've come across a similair issue in the P40 I can use the auto mode but the throttle will get to 80% then won't go much higher. I thought this might be done on purpose to avoid a blow out or something but maybe not?

Yep, if you use automated engine management, it will prevent you from using throttle settings that would damage the engine.

 

BTW: To avoid possible confusion: The Allison engines of the P-40 and P-39 don’t have automatic boost regulators, so manifold pressure will vary quite a bit depending on air pressure (which again depends on weather conditions and, more importantly, altitude) 

As such you might be able to use 100% throttle with no issue at high altitude, while that same throttle setting will blow the engine in 1 minute at low altitude. When using complex engine management with the Allison engine there really is no substitute for keeping an eye on the manifold pressure.

Thanks for the advice everyone. I am not at my PC right now, but I’ll check if I’m fact I do have CEM selected. I thought not, but I guess it is the most likely culprit. 

 

I am intrigued with flying with CEM on non-109 / 190 Aircraft, but I am dreading the learning curve. 

 

There is so only so much time I can devote to BOS, and I have so much fun flying campaigns, that I can’t bring myself to sacrifice battle time for flight school. 

 

Anyway, love this sim, and it has a great community 

[unreasonable]

Well have a first arrow for saying thanks: it is amazing how many people do not. 

 

If you have Bodenplatte early access I recommend learning on the Spitfire IX which has only boost (ie throttle) and rpm control to worry about: fuel mixture, oil and radiators, superchargers are automated so you only have to worry about the relationship of boost and rpm, which is the key factor: i.e. two levers instead of one.  If you do not have Bodenplatte, learn CEM in the Yak 1. You will have also have to control oil cooler, radiators and supercharger manually but it is fairly robust so you can get things a bit wrong without it blowing up. It took me about half an hour to get the hang of the Yak CEM after coming from simple WW1 aircraft..

[Tinku74]

Thanks unreasonable. Sounds like reasonable advice (sorry, I’m sure you get that a lot).

Hello,

 

I have throttle mapped ONLY to the z-Axis of my joystick. 

 

However when I jump to e.g. the La-5, moving the joystick slide has no effect on the throttle. Instead, I see the animation of the RPM lever moving forward and aft. 

 

If I map throttle also to the default =/- keys, same thing happens, RPM lever moves, but I get no power, can’t even take off. 

 

Leave same bindings, jump to a 109 or 190, and can soar like an eagle (or rather waltz in the air like a drunk fly). 

 

So...any other ideas?

 

 

[Finkeren]

If you start out with an aircraft with a less sensitive engine, the learning curve is really not that bad. 

 

The Klimov V-105PF engine, which is used by the LaGG-3, all the Yaks and Pe-2 s.87/110 is really very easy to use. As long as you stay below 4000m altitude you really only need to focus on 3 things:

 

1: Coolant temperature - watch your temp gauges and open or close the 2 radiators to keep them within the limits (generally you’ll want to keep both in the 70-100 degrees range)

 

2: Supercharger gear - you need to shift gear on the supercharger when you change altitude. 1st gear below 2300m and 2nd gear above.

 

3: Throttle movement - you regulate your power output using throttle. Since you are at max rpm be careful not to slam the throttle forward or you can potentially insta-kill your engine due to over-rev.

 

With the Klimov engine you can leave rpm and throttle at 100% all day with no consequence, as long as you keep the coolant temperature down. Mixture you can leave at 100% up to 4000m as long as you remember to shift supercharger gears.

[Tinku74]

Thanks Finkeren. I’ll first try to find out how I can get to fly the Soviet planes with automated engine controls, to get a feel for them, and then I might just follow your and unreasonable’s advice. 

[Finkeren]

With the Yaks there’s really not a whole lot to “get” about them. They are pleasant to fly, forgiving and very simple to operate both in the air and on the ground. On top of that they are quite capable as fighters, even in unskilled hands. They are the perfect beginner’s choice IMHO, and as said their CEM is so simple that it’s hardly a barrier at all: Manage temperatures, remember to shift supercharger gears and you can hardly screw up.

Running out of them. Whenever I have had problems with controls it has always been something in the keybindings, but I am still not sure what your realism settings are. Possible some realism helper is interfering. 

 

If you have not already, untick all the difficulty setting boxes to disable any helpers. Then make sure you have 1 and only one set pair of buttons or an axis mapped to engine throttle control and another pair of buttons or an axis mapped to engine rpm control in settings/keybinding/engine controls. You must have both.  Check that there are no orange boxes in either line indicating duplicated choices. If there are any find the other line using that entry and delete it. 

 

Now try runway start again. Make sure you operate both button sets/axes to calibrate them with the game animation.  At full real settings the two controls should move independently according to their own key binding with no interference from the AI.

 

If that works you can start to worry about water/oil/fuel mix   If it does not I am at a loss.

Culprit is probable "engine aids".

Thanks Sokol1, mystery solved. It is a pity. But at least now I know it’s a bug, and that I am not going crazy. Well, at least not over the the throttle thingy...

 

Who knows, maybe now I’ll even give that Yak a try with CEM...

 

I really appreciate everyone taking the time  to try and help out!
