Fascinating, thanks for sharing
Cool! Thanks.
Well done any chance of the same for 2 seaters
I like them!
That first graph shows some interesting things for the SPAD XIII. It shows that it has the fastest climb rate out of all the planes that we currently have in WoW.
I'm very sceptic to the graphs going up anywhere after sea level, unless the engine being designed specifically for high-altitude use, like the Maybach Mb.IVa. That engine had too big a compression ratio, meaning that it couldn't use full throttle at sea level without blowing up, but in the thinner air could be run at full power. Other normal engines loose power with altitude. And power should be everything for these planes, except the ones with high altitude engines, like Fokker D.VIIF with it's overcompressed BMW IIIa, Pfalz D.XII with it's overcompressed Mercedes D.IIIaü and maybe the S.E.5 with it's high-compression Wolseley Viper. So some of these graphs doesn't make sense to me.
Cool graphs. Was that put together in excel. If so could you upload the file please.
It looks as though the D.XII and the D.VIIF are the only two models with any significant increase in speed as altitude is gained (15 and 20kmh respective). Surprising, the D.IIA gets an 8 kmh boost between 4 and 5,000 meters in altitude, topping out at 173kmh.
(The N-17 gains 4kmh [156-160] as it rises from sea level to 1k, but losses that speed as it continues to climb, with a speed at 5k in altitude of 148kmh)

I didn't create it, and it was posted from whence I acquired it, as a PNG file.
The graphs show some very interesting things.
If I read this right the 2nd graph shows the N11 being faster than the N17.
It gives the Dr1 a bit more speed than it it generally credited with.
It also highlights how the BMW engine turned the Fokker DVII from a good plane to a great one.
Pooh
Looking closely at the performance details of each plane (N-11 and N-17) it appears that the second graph has them mixed up, one for the other:

The Siemens-Schuckert D.III and D.IV do not seem to be on the graphs and they were supposed to be able to outclimb anything.
Brian,
The N11 & the N17 are reversed on the 2nd graph.
That's what i thought too.
Pooh
Still if we were to use this chart for our card decks, the Pfalz DXII and the Fokker DVIIf would be in the same speed range as the Spad XIII & SE5a.
The Spad XIII would have a better climb rate.
The Dr1 might be moved up a speed band, if not the Sopwith Tripe should be faster though the Dr1 should outclimb it and the Camel.
I think I'll leave things be but it is fun to see some more specific information than averaged climb and speed with no altitude listed.
Pooh
