Performance data?
 

I often see references to optimum 'cornering speed', 'Combat speed', etc, but cannot find any information regarding these for BOP fighter planes in the 'stickied' threads. Is this data available anywhere on the forum?

nope just people bitching about a patch that is never going to come out

Im sure someone did something to sort out stats for some of the planes. Will try to find it if i can. In the mean time you should get online since we've not seen you for 3 days!! :P got a free flight going on here with jack to try and get some of the basics back. I'm a severe rookie now :( lost the edge.

:grin:....Unfortunately, I am away from home three nights each week (in my VWcamper....in this frigging weather too!).

I don't think any of us have actually made a collection thread of the cornering speed and combat speed of the plane models in BoP because we've usually just gone on what I and others have said about the actual planes, BoP isn't very accurate with the speeds of the planes. But Kozzom0 and SgtPappy had a discussion on it, or something similar a week or two ago? (I think it's somewhere on page 2-3?) But their info was wrong because they were using the wrong stats for the wrong engine. I think it was SgtPappy who made the thread?

Cheers Soviet, I will have a look at the threads anyway. I'm mainly interested in the LA's and the Spits.

There are performance specification tables in the sticky titled " A beginners guide to the planes" I believe the link is in the first post.

I checked that thread before posting the question BeaverCo but unfortunately it doesn't include that data. From what Kozzmo says in other threads the Spits optimum Cornering speed is around 185 mph. Just need the LA's now.........

you tried looking at this it mite have some of the stuff your looking for

Looked at that thread, the data references 360 deg turning time at 'Combat Speed' but no mention of the speed used. Maximum speed for each a/c is given but nothing else.

Maximum speed etc and radius of turn all depends on how you have your sensitivity set up. It would be hard to universally agree on a speed and radius etc :(

I am not sure, but you probably refer to the detailed test data that I compiled and published in this thread concerning 22 BOP aircraft :

[--->] Detailed BOP test data for 20 BOP aircraft available here!

If so, then maybe you overlooked my explanation of CMS as used in the testing:

"Combat manoeuver speed (CMS): Maximum level speed, minus 360 degree horizontal turn speed drop, plus ~10 second WEP acceleration after that."

The reason that I finally used this CMS formula in some of my testing is due to to something that became apparent during the extensive testing that I undertook over the period of a month: IL-2 BOP aircraft performance cannot really be compared to real world aircraft performance. The IL-2 BOP flight models are just not accurate enough to find the so-called optimum cornering speed in BOP. In real life this is certainly important, but the IL-2 BOP flight models differ too much from real life to take this into account in BOP. The maximum speed figures attained for the 22 BOP aircraft included in my test files also make this quite clear. For that reason I used CMS, which is a speed formula that is closer to the speeds that players fly in BOP multiplayer online. In order to test a game, one needs a game test formula and not apply a real life testing formula is a conclusion that I reached based on extensive testing of BOP. I tested a lot more than I included in the three files that I posted on this forum, which led me to this conclusion.

To have some idea of how insignificant and strange the differences can be, take a look at the "Widar Thule BOP sensitivity testdata v1.0.zip" file. In that you can compare the CMS results with 300 km/h results at various sensitivity and flap settings for the Ta-152 H-1, which was arguably all-round the best piston engine fighter of WWII in real life. Basically the fastest horizontal turn is attained at around 300 km/h with combat flaps, under 300 km/h you are just too close to stalling in simulation mode. But flying at 300 km/h also makes you a sitting duck in BOP online. The fastest role, dive and climb results on the other hand are attained at CMS without combat flaps. So CMS is the way to go for most BOP players online, which in effect means that flying at WEP and close to your maximum speed is generally best for all-round manoeuvering in BOP. To take it any further than that in BOP is useless because the BOP flight models just differ too much from reality, there really is no need for further hair splitting than that.

And as aircraft are concerned, Soviet and British aircraft are the best in BOP, the La-7, La-5 and Spitfire specifically are the best aircraft hands down all-round in BOP and in that order as is evident through the data in my test files. I do not mean in real life to be sure, just in BOP. Hopefully the upcoming BOP update (I am on the Xbox 360) will make the USA and German BOP aircraft perform more to real life vis-a-vis the Soviet and British BOP aircraft, since the USA and German BOP aircraft performance as it is now in BOP is generally all-round disgracefull when compared to real life. If that Xbox 360 BOP update ever arrives I will do some new tests to see what has been changed in the BOP flight models by the developer.

Thanks for the explanation, I did overlook that (probably because I didn't understand it :confused:) but much clearer now. Very informative.....cheers! ;)
