In case of the PC-12 at MTOW this would mean it should be centered for flaps 0° at approx 118kts, 15°/96   30°/88   and 40°/83.

As close as i can get to this Table is with a value of
...number) 2.35 - /-/ }</Script>

0°  /125kts
15°/95
30°/80
40°/72

I can't find this gauge file:

Gauge_EFIS_EADIVCV4.xml

 

I have the PC12 v2 for p3d v4.1

Is this the gague for the S550 maybe instead?

That's quite a big gap, especially at the 40° position.

It should be "Gauge_EFIS50_EADIVCV4.xml" from the Bert Mod...

Maybe Bert can help:

• What value has the variable (A:Angle of attack indicator, number) ?
• Is this a Multiplier 1.88 - /-/ } ?

To get closer to the required Table it should be something like this:
<Script>(A:SIM ON GROUND,bool)  if{ 0 } els{ ((A:Angle of attack indicator, number) +20) 1.62 - /-/ }</Script>

We have to add a fixed value to the variable to get higher kts at the certain Flaps-Positions together with the Multiplier!

I can't explain it better with my bad english

You did explain it very well, but it looks like in FSX/P3D you can't use different values, so there's no way to get it to work as IRL.

I know, but if you add ONE fixed value to the variable and than multiply it with something, the result increases equal to there size value ?!?!

I am not a mathematician but i tried it theoretically and it comes closer to the "Table".

But i don't know if "(A:Angle of attack indicator, number)" is like 125 or 1.25 or 0.001346 confusing...

"A:Angle of attack indicator"  is a standard P3D variable that is measured in Radians , ie an angle 

It has a maximum value of 3.14. as best I can tell... maybe it is hundredths of a Radian...

The gauge subtracts a fixed value (1.88 or 2.14) from this value, and changes the sign from +  to  -.  This then is the shift distance for the pointer which goes from +1 to -1.

There is no direct relationship to airspeed..

That may helps, my personal fight

I will play around with it and try to figure it out...

Ok, i tried a lot of very complicatet calculations including calculating parabolas, to optimise the indicator (btw i learnd a lot) to finaly found the easiest way to get close to the Table:

<Script>(A:SIM ON GROUND,bool)  if{ 0 } els{ (A:Angle of attack indicator, number) 2.25 - (A:TRAILING EDGE FLAPS LEFT ANGLE,radians) - /-/ }</Script>

At any Flap-Position, the Value (ie 2.25) had to get a certain amount higher (in a smooth way so the needle won't jump to much) to correct the display. It limits the way to the (F) direction with each Flap-Positon, but that won't bothers to much.

Now i get these values (at no wind, clear sky, 600 feet Alt):
0°  /118kts
15°/96
30°/88
40°/81

Tata... free to try

 

Hi Raller,

Thans for your efforts - I’ll try it when I get home this weekend...

Regards,

Scott

Neat stuff 

Edit: Just tested it.. it works!

Very nice!

Personally, I am going with 2.14, rather than 2.25 just so that the indicator can go all the way to the F (Fast) mark.  But that is personal preference.

 

I have included this is the latest roll up of the various mods: V5.7.

Are we going to see V6.0.? 

Guys,

Great work all together!

Marcel
