I've been testing SPAW with 1.28c exe.
I've read the 'readme' of 1.28c exe that mentions additional aircraft info...



Could someone from the Code Group explain what the figures
in the upper righthand corner of this screen shot mean...

Cheers mates

Ralf will explain the best altitude settings, but the framerate, mass in kG/lbs, and indicated airspeed in mph/kmph are self explanatory.
The mass values were really useful to us when we had a fuel burn rate 10x larger than it should have been for the Typhoon and P47C in the 1.28b release (as we could not see the last "0" in the planes.dat editor LOL), and we could see the mass dropping very quickly.

Hi,

the best alt values are related to the two possible supercharger stages.

best Alt 1: current best Height(rated height, highest power) of the 1st supercharger stage in feet
best Alt 2: current best Height(rated hight, highest power) of the 2nd supercharger stage in feet
best Alt diff: altitude difference to the current supercharger switch height in feet
(when this value is = 0, you be in the current supercharger switch height, often the worst power)

Like in reality this heights are in big degrees related to the current plane speed(ram air effect).

As such you will take notice that the height vary with the speed.

In older FM´s, also still in SPAW, no 2nd supercharger stage got implemented for now, so the 1st supercharger height is = 0 and also the switch height is close to zero.

So in EAW1.28c the rated altitude change with the plane speed, what is another very ealistic aspect of aircombat with piston engines.

Important to know is that the engines wont overheat if the plane is a little above the current rated altitude. This is so cause above rated altitude the engines cant get loaded with the full presure anymore, as such the engine run more cool.

So if a plane have two supercharger stages, there is a altitude band, above the 1st rated alt and below the supercharger switch height, where the engine wont overheat and then again above the 2nd rated alt.

That's pretty cool having that info handy, Knegel. Nice work!

Thanks Ralf,

Having these info figures available to the pilot is a really nice little feature of 1.28c

btw, look to the weight while you push the gun trigger.

The EAW1.28c flightmodel also take the amunition weight into account.

So a FW190A without amo is around 250kg less heavy and it will perform like that.
The P47 is around 450kg less heavy without amo, while the 109G6(clean) just carry around 90kg amo and the Spit1a just around 75kg.

So depending to the current fuel and amo load the performence relation between different planes might vary much.
