I have to say, MAW looks very nice.  Truly a huge step from the original CFS3 package.

I wonder though, will engine RPM gauges read in snchronism with engine RPM, or will they remain at a fixed reading regardless of engine speed ?

I also wonder if boost gauges will have the notorious CFS3 standard atmosphere error fixed ?

My guess is probably not.

None the less, it's obvious there has been a great deal of effort, skill and talent put into MAW.

"""I wonder though, will engine RPM gauges read in snchronism with engine RPM, or will they remain at a fixed reading regardless of engine speed ?"""

Engine power output is measured by the Manifold Pressure gauge not the tachometers.

The tachometers are not measuring engine rotation speed but prop rotation speed.

Have heard the term Constant Speed Props?

Ok, first: what a beautiful example of gauges ! if this is typical of the MAW standard we are all in for a real treat. I'm impressed.

In my previous I refer to the fact that all MS sims seem to have been stuck with the notion that the 'RPM' indicators should read maximum engine RPM, at all times. Obviously, this is incorrect.  These gauges are not intended to indicate power output, they are clearly meant for engine RPM.

As an example take a look at the AH Spit, you have a tacho which always displays ~3000 RPM. This cannot be prop speed since, if my memory serves me right the engine has a reduction ratio of 2.38:1. Hence, if the prop is doing 3000, the engine must be doing 7,140RPM. Actually a merlin  is rated at 2,800 approx.

They are not prop RPM gauges, and never were intended to be so.

The standard atmosphere issue I refer to can be seen on all CFS3 aircraft boost gauges. I'm not in a position right now to go into depth (I'm working remotely) but, a number of simmers noticed boost readings off the scale at maximum and minimum throttle, way off as compared to the older CFS2 stuff. I looked at this and found it basically due to a 30" difference in the boost scaling for the two sims.  CFS2 boost gauge readings were cock-on, CFS3 boosts are off the scale that much is clear so I assume there is an error somewhere.

None the less MAW is looking excellent,and for freeware I think no one will be disappointed.  Personally I would have paid for quality like that.

Spitfire full throttle 100% RPM

Salutations

you obtained varying indications on this gauge because  correctly you altered the pitch.

Even on the principle of a constant speed prop, this gauge is meant to register actual engine speed, nothing else. The engine speed is governed by the throttle setting, not the speed of the prop. i.e. regadless of pitch setting, if I throttle the engine back to idle for example the engine RPM indicator should show likewise.

The 'simulator' has this gauge linked to pitch setting - wrongly I believe. In my opinion MS originally has a pitch gauge scaled as an engine RPM gauge and somehow this trend has stuck.

I used to have downloads which had third party engine RPM gauges, these did what they were supposed to do so clearly they were somehow not linked to pitch function.

Bear, Here's a question: If I am wrong and this gauge reads prop RPM, what would the tip speed be for an eleven foot prop at 3,000RPM ? Can't work it out in my head but I think it might be perilously close to mach, if not exceeded.

There cannot be a situation where the gauge is both an engine tacho, pitch gauge, and prop speed indicator all at the same time depending on how you look at it.



Re: boost-

I just ran your excellent Mkix spit as a fresh download and checked boost. Yes mine definately goes way past 20 at full throttle, yes I did calibrate the stick.

I do seem to remember looking at this a while back and found CFS3 boost gauge input exceeded gauge span at both ends. As far as memory serves, I think I had to pull in the lower end boost gauge idle setting using one of the throttle sections in the airfile. It was then necessary to get the 'top end' span point correct via the cfg. I'm pretty sure the difference actually coincided with 30" mercury. This may have been coincidence but was noted with several CFS3 models including stock.

Not wishing to get misunderstood, simmers have had to live with certain glitches/inaccuracies throughout the entire series. I would bet the MAW team will have made great effort to iron out as much as possible.

Look forward to the first download.

I just used a bad example to try to uncouple manifold pressure, throttle position & RPM as I did with the pictures, seemed like a good idea at the time.

In flight the constant speed prop will cause the engine to spin at 3000 RPM. On the ground at idle the RPM will reduce to the idle RPM. Some aircraft/prop combinations the prop governor will not be able to compensate and the RPM will fall off a little at low airspeeds.

AvHistory's new Version 4.0 corrects all the ground idle RPM's, also as for supersonic props, the TU-95 prop tips go supersonic at high speed cruise & max speed.

There is no generic notorious CFS3 standard atmosphere error or all the gauges in the sim would be off which they are not.

I think we will have to agree to disagree on the RPM gauge issue.

As for boost, I can only say mine definately does what I said. However some information has come my way which might suggest a stick 'span' issue particularly on throttle axis in my case i.e I might be over spanning despite calibration. So I can offer no firm opinion on boost since it looks like another variable might be involved here. I have to check this out, time etc, etc.

I followed the link for the Bf110 panel, truly stunning.
If only that panel and cockpit were available for FS9 also. Perfect workmanship, just perfect.

I strongly suspect the same quality is going to be evident for the rest of the MAW aircraft. I do wonder with quality like this why it should be that the MAW 'team' needs the MS core ? surely there is enough expertise here to go it alone ? in my opinion at least.

Regards & thanks

On the stick "span" are you aware this same issue exists in Falcon 4; all versions?  My TM TQS is effected by this & in many cases when you enter the cockpit you need to run your throttle up and down a few times before the game "sees" it correctly.

As for not using the CFS3 core......MAW has taken about two years to get ready for Chapter 1 with almost 50 close collaborators & may have taken more then twice as long if we built a ground up system, the "war" we envisioned is so much more then just the planes.







We really wanted to invest our collective time on the content & not as much on platform.

Not bad, not bad at all

There is going to be something for everyone in this.

Those gauges look fantastic. MAW is going to the best add-on this sim has ever seen !!

Many thanks to the MAW team for all their efforts.

What I would really like to be able to do is extract the data from the game so I can run those great looking gauges on a seperate monitor in my simpit. While I'm at it I could also use the same data to drive my motion platform that I want to build. But it is only a dream.

cheers

Wow, Av, I've never seen ground troops. Thats awesome

The camels, horses, sheep & cows will also add something for the troops to watch out about stepping on/in.  The birds will also encourage them to keep their helmets on  ;D
