1. For those who does not have a sophisticated throttle system... can we have a key set that locks the RPM controls and throttle controls together?
Like, "CTRL+L will lock the RPM control to correspond to throttle lever"..? This would be pretty cool option for people who'd like to interlink those two controls and reduce workload. Since the new fuel burn model I admit I've been using a lot of RPM controls in many situations.
2. Can we have a "bomb lock" key?
In most fighter bombers, the bombs and rockets and etc ord. are something you have to consciously switch to - since secondary armament is always either a machine gun or a cannon. No worries there.
However, in something like the Ju87 that carries just one bomb, a slip of the thumb may cause a frustrating result. There is no secondary armament in the form of guns, so the secondary fire always directly releases a bomb.
If adding in another key is not desirable, then how about adding an off" status between the cycling of secondary armament/ordnance?
For instance a gamer is flyign a Ju87D with 1x 1800kg bomb. He is worried if he might slip his finger and lose the bomb. So, if the player wishes, even though the default is the "180" bomb state, he will press and cycle it to "OFF". If he wants to use the bomb, he will press again to cycle it back to "180" and use the 1800kg bomb. This seems like a simple thing to do..(I hope...)

You can map the RPM to the throttle axis now (to combine the two) within AH
-
How do you do that?
I've tried it, except whenever I do that the RPM axis is opposite to the throttle axis - which means, if I raise throttle with the lever, the throttle goes up but the RPM goes down. When I lower the lever the throttle goes down but the RPM is adjusted up.
How do you reverse it so the RPM levels correctly correspond with the throttle lever at the same time??
-
Good points Kweassa.
If nothing else a "Master arm switch" that safety's the system could be implemented.
-
On the bomb thing I agree..
I've had my thumb slip 1 or 2 times and drop that bad boy on the 87.:eek: oooppssy:eek:
I found it quite annoying after flying this particular slow bird halfway to a base.:)
-
Side question: What's the difference between throttle and rpm (in the game AH2)?
I've just been controlling the throttle, and observed the rpm gauge varying accordingly, as one would expect given the definitions of the 2 terms.

You have tick box to invert the input...............its exactly how i have my rpm and throttle set

For all the current 190s, throttle should be linked to rpm, and none of them should be allowed to operate alone.

Prop pitch varies rpm ( which will vary manifold pressure ),
Throttle varies manifold pressure ( which will vary rpm ),
this control is independent if the controls are unlinked.
It makes it easier to blow the engine up, if modelled correctly. Most WWII aircraft are independent, some are linked.
Is it 'combat trim' that links them? I tried it in the beginning, but stuck with the default to reduce cockpit load.

They are not linked in AH in default set up the RPM can be set by the +/- keys on your keypad.........
or as above you can map it to an analogue input (roller on a HOTAS) or map it with the throttle.
Plus side of mapping with throttle is that you have better fuel economy. Down side is that the prop feathers when you throttle back so it does not scrub speed in combat........ for this you have to leave throttle full on and switch the engine on and off (if you really want to go that far)

Why does that happen (IRL, I mean)?
-
Changing the RPM changes the supercharge speed, hence less manifold pressure for the same throttle setting.

Got it. But then, how is boost controlled? I thought there would be a mechanism to regulate boost...like with a turbo. So that, no matter what the rpm, the boost is always "too much", and is regulated to a max level. How is SC boost regulated (or maybe it isn't)?
-
Dump valve/ waist gate. Thottle bascly just controls a butterfly valve at the manifold intake. Supercharge just runs at a constant speed per engine rpm, with a gear changes for high blower. Any excess just pushes out the spring loaded waist gait.
-
In that case, wouldn't it be true that for most of the useable RPM range, boost stays constant? Just more gets dumped out at higher RPMs.

Does this only work with HOTAS? or can a combo stick be coupled as well?

Sorry I did not get time to take u thru this last night Mugz.
From the clipboard........
setup>controls>select joystick
The clipboard now displays three windows entitled
AH Control. Joystick. Joystick Input.
First check that which ever device you use for throttle is the one highlighted in the middle window (joystick).
If it is not then click it to high light it.
Now we need to find your throttle axis.
Scroll down the AH Control window (left one) and find "throttle 1". then click on it and note which axis is now high lighted in the Joystick input window (right one). Make a note of this axis (it may be Z or something).
Now scroll down the AH Control window (left one) again and find "rpm 1".
Click it to high light it.
In the Joystick input window the word should be highlighted.
Now click and highlight the throttle axis you noted above and click the button "set input".
Click OK
Re open the select joystick page and check that both throttle and rpm are now mapped to the same input.
Leave this window and then go to the "settings" page (setup>controls>settings).
In the top left scroll the text window to RPM1. and select it. Moving your throttle should now cause this to rise and fall in the plot line chart on the right.
Note the box that allows you to invert the axis. If you find that the rpm increases as you decrease the throttle then you must tick this box to invert the rpm axis to synchronise them both.
If you are into multi engined ac then you may have to similarly map rpm 1 to 4 to the throttle. But play with just the one to start with.

Varies with ac's aspiration design and altitude (ie air ambient density) as well as ac speed (air ram into the inlet duct)
Also the "efficiency" of the supercharger is not constant.
eg in an La7 below 7000 ft boost is limited to 1180mm merc (presumably by the dump valve or a restrictor control) when in WEP. As the La7 climbs above 7000 the thinning altitude means that the supercharger can no longer generate this boost pressure and MP and power drops off until an altitude is reached where it is safe to switch to the 2nd super charger speed.
Efficiency (or the lack of it) is shown when we compare engine rpm and boost pressures.
At 7000 ft at mil power the engine RPM is 2400 and the boost pressure is 1000 mm. Yet at 7000ft at WEP RPM is 2500 and boost pressure is 1180 mm.
Boost has increased by 18% for only a 4.16% increase in rpm. Yet we see that super charger speed isat a direct ratio to engine speed and we are at an altitude where there is no excess boost to be dumped/vented.
Hence as we reduce rpm, boost pressure should fall away rapidly to a point where it is only ambient pressure plus ram air pressure.

why the 190's? :confused:
-
there was a "Kommandgerat" computer that tied everything to a few (if not single) engine controls.
See description starting with Crumpp's first post in this thread:
http://www.hitechcreations.com/forums/showthread.php?s=&threadid=131502&highlight=bmw+computer
In that same thread is mentionned the Kommandgerat could be overridden in all 190s A-3 and newer.

In A3 it wasnt overridable.

right, I misread that.
Thanks.

Interesting! Thank you.

Mmmmnnnn, I thought Aces High was set up to avoid extensive engine management controls in favor of enhanced gameplay.

I think I may be able to do that within the current system. I'll give it a try and see if it works.

I'd like to see a way to tell which set of bombs are primed to drop on planes like the A-20 and Mossie. If you are carrying 500s on the wings and internally, it's easy to confuse which are set to go. It would be nice to have an indicator of which are set to drop.
In the past I've used the 250 on the wings and 500 internal system, and have practiced enough now to know as I cycle the Backspace key which bombs are which even if they are all 500s, but it can be very confusing for less experienced players.
<<<>>>
I've read many combat stories of excited pilots forgetting to flip their machine gun/cannon arming switches, pull the trigger, and nothing !
I wouldn't be surprised to see weapons arming becoming a new feature as AH continues to add realism to the simulation.
The secondary OFF is a start in that direction.
-
I recommend mapping the RPM control to the mouse scroll button.
-
Pyro, can you also make a single button function to salvo all ordnance at once?
-
Thanks for checking it out Pyro :)
-
Tilt,
Thanks for the details on mapping the rpm to the throttle. I just did it, it works great. It even tracks to the EGB reccomended setting for Max Cruise ect.
