Replacement groups come with free pilots that average what the experience level set for that group in the airgroup editor


Any idea if that applies to the initial pilot complement only or to all pilots, incl later replacements, drawn for the sqd - ei is the XP set in editor an absolute override?



I am assuming that it applies to the initial pilot complement for those squadrons that start on the map also. In a quick check of all the squadrons that start the game on map, all of them have an experience level set. That would, or should, mean that all the pilots in that group must average an experience level of the level set.

I know that the experience level can be set for every group in the editor or if left at 0 the game will provide an experience based on the table. The table gives the "0" experience level for each nation by year from 1941 - 1946.




This is correct: IF you bring in a new unit in a later year and do not define the experience level you will get the default table values. And in an exceptional case you can define it differently. Genda's Flying Circus is such a case I think. It hand picked pilots and it was the last truly effective JNAF fighter unit. When it set up a patrol line from Tokyo to Kyushu and brought down numbers of B-29s, the American prisoners were very impressed and said so.

I ran a test, which seems to confirm that subsequent replacements doesn't get the XP level of the sqd as defined in the editor. It is thus possible to put a sqd "in training" on the map as was the case with many US sqds on the west coast.

I guess I wasn't sure what you exactly meant. If you are saying that your test that a squadron listed as arriving on 1 Jan 43 comes in either at an experience level that was entered when the scenario was created or set at 0 and arrived with an experience level based on the table in the manual and a new replacement pilot was needed, it will not come in at that average experience level of the squadron you are absolutly correct.

The replacement pilot brought in would be based on the experience level of all new pilots based on the table that is established in the scenario via the scenario editor. If this pilot exceeds the number of pilots for the month, then his experience level will be around half of the original. For example: If the Dutch is allotted 5 pilots per month at experience of 40 and if you bring in a new pilot to a replacement squadron, or any squadron, the pilot will enter the squadron averaging 40 (this may vary between 31 and 49 IIRC). If this pilot was the 6th or later pilot for the Dutch that you requested during the month (whether it was the 6th for this squadron or the 1st for this squadron but the 6th overall), then the pilot would enter with an experience of approx 20 (11-29) and added to the squadron.

So if the squadron was showing an experience of 35, it would go up in the first case generally and would go down in the second case.

Does that help?

You understood the question just fine first time round - least going by your answer :)

Cheers!

I have Japanese plane data. I should be able to do 5.10 on schedule - tomorrow.
I have folded in a lot of corrections until now - except for leader corrections - which remain elusive.

we say "every 2 points above 29 is needed to up the score by 1" -

so 41 (12 points above becomes 4) = 33; 42 (13 points above becomes 4.5 rounding up to 5) = 34

both acceptable.


OK, the post is already 3 days old, but still, it looks like a very strange way to compress things as you use a composite function (with special case above 29). So basically you use one "knee" to fight the other. How about using a simple polynom instead, i.e. f(x)=a*x^n ?
If you use a=1.1 and n=0.9 (so you use 1.1*point^0.9) you get 47 down to 35 and the first 'small' number which gets rounded down is the 7 (f(6) and f(7) are both rounded to 6).

Assuming that your original formula does produce real numbers anyway, an approach using a polynom is much more continuous (well actually continuously differentiable) than a composite function. Just follow the motto: Use non-linear functions if you want non-linear results.

Not a bad idea - altough I am opposed to including the one anomolous 47 in the set at all. If we disregard it, our set ends at 42 - a much better place to begin. The concept of treating jets different probably will be useful: we may run into it again. The problem here is time: it will take time to work this out and apply it to all cases. It is surely faster to just modify a few by a simple rule than to modify them all! Also - I am concerned - we have such nice values for way over 200 data sets that compressing them may cost us this nice relative evaluation scale. I would rather limit what we mess with to the few high end cases. Anyway - its fast - so we will try it first.

Zemke -> RE: RHS Maneuverability Review (11/23/2006 10:39:32 PM)

I missed this conversation back in August, I was sort of unable to respond, but reading the all this I decided to throw in my two cents worth.  I just completed a complete re-work of all plane maneuverability ratings.  I used the data from a flight sim game called "IL-2 Pacific Fighters", which of course has its own sub-culture like most games that develop after market tools and aids.  One of those "aids" is called IL-2 Compare, which has plane specific data, to include best speed at all altitudes to best turn rate.  (There are several versions of Compare, as it is updated each time the game is.  For this I used IL Compare 3.01.  The newest version is 3.04 which I did not have on my laptop.)  If you fly, you realise that manueverability is more than turning and never really constant, because as you turn you "bleed" off energy.  The Zero was so maneuverable because it was so light.  Anyway, as a compromise I used the best turn rate in degrees per second for each plane, then doubled the number and that was my constant.  My reasoning was what better source than the best World War II flight simulation.  I play the game IL-2, I have found that every plane has strenghts and weakness.  Anyway the results were most Japanese planes gain maneuverabilty, some Allied planes gained and some lost.  Of note, the Spit gained, La-7 gained, all bi-wing planes gained, the F4Fs gained, the F4U lost, as did the P-47, and P-38.  I also used the best speed rating for the "speed" and found the maxium speeds changed very little, with some exceptions.  The P-38s gained speed, and several of the Japanese late war planes gained speed also.

Well, actually, as you will see in this thread, and two preceeding threads on the same subject, we do understand what maneuverability is. I got to study aircraft maneuvering early in life as an anti-air warfare specialist in the USN,
and I also got to learn to fly in a Navy flying club - which helps one have some perspective. Later I worked as a resident computer engineer at a USAF Software Integration Laboratory at Boeing. So aside from some personal interest in these matters, I have also had some formal exposure to them.

The basic problem with the simple WITP system is that we must give each aircraft a single rating, regardless of altitude, speed, flight regime, instantenious loading, etc. for both horizontal and vertical maneuvering. We have elected to go with a composite rating system. And we simply do not permit a plane to reach its service ceiling - where its rate of climb (by definition) is 100 feet per minute. [RHS uses an operational ceiling which is halfway between optimum operating altitude and service ceiling - so our planes never are completely at their worst for maneuverability].

The problem with your approach is that we do not have turn rate data. You cannot look this up in a standard reference for most types, and it was not even measured for more than a few types in our data set. Nor is there an easy way to calculate it. We elected to use values which were either directly available in source materials or able to be derived from it. It is present here mainly as a function of wing loading, modified by power loading, and greatly modified by the number of engines (or 1 if the engines are on axis). The goal was to achieve a single, openly defined, objective system permitting anyone to calculate (or verify the calculation of) maneuverability - so we don't have to depend on the game designer's classic seat of the pants guess ("it is not quite as good as a Zero so make it 2 points less"). If one does not expect too much of such a simple rating system - and if one does not place too much weight on a single factor (when several define a plane) - this system seems to be rather good at indicating the average differences betweeen aircraft. Not only does it clearly distinguish between the maneuverability of gigantic 4 engine aircraft and tiny single engine jobs, it usually indicates the relative differences between similar planes correctly. Until we have more fields - and a more sophisticated air combat model to use them - it may be as good as we can do? What might change is the constant K - if we can show a statistical skew we might be able to compensate for it by adding a constant.




elcid -> RE: RHS Maneuverability Review [Updated] (12/20/2011 12:19:08 AM)


In Re this question posted long ago:

I can understand your rationale regarding 2-engine fighter types before the use of PL and WL. By using these in the calculation, are you sure that you are not penalizing 2-engine fighter types twice? If not, what is inherently unmanueverable about them when combining speed, ROC, PL and WL? I understand reduction added to 4-engine planes as they were not built to withstand excessive G forces. This would impact many 2-engine bombers as well. Are you also saying that 2-engine planes designed as interceptors could not handle the G forces that a single engine plane could?



With the qualifier that this is a simplification of reality, seeking an approximate truth for simulation purposes:

It is not a matter of handling G-forces per se - I am not worried about the wings falling off for example.
It is a matter of angular momentum. Engine(s) on the centerline have a wholly different impact on roll than
engines offset do. Ideally thrust should occur on the centerline of the aircraft, not out on its wings. To
the extent this is not the case, there is a penalty to pay in maneuverability. This gets worse as the number
of engines increases. And note a twin engine aircraft with BOTH engines on the centerline does NOT pay
the penalty. This occurs two ways - when extension shafts permit two engines at the nose - or when
there are nose and tail propellers. That is why those designes were done that way - vice putting the
engines out on the wings.
