Hi,Is it possible to get the following values in xml?Alpha Protection Speed, Alpha MAX and the VMAXBrgdsEugen

Eugen, VMAX should be able to get via A:Airspeed barber pole. The other two would have to be calculated based on performance charts using items such as A:Total weight, A:Flap position etc..I took the performace charts for the 734 and created a furmula to calculate them. The formula approximates very darn close but not exact.. ( +/- 2 knots ).Attached is an example pic of what I did. You would then have to calculate each speed factor for the necessary flap positions the provide a IF statement to send the correct flap setting factor to the formula..If flaps1 then "speed factor 1" (>G:Var1) If flaps 2 speed factor2 (>G:Var1) etc....Then for the example shown here to find the speed (in this case V2):(* THE FINAL CALCULATED V2 *)(A:Total weight, lbs) 80000 - (G:Var1) * 125 + I used the same procedure to find all the speeds necesary to display on the EADI.. Min/Max flap speeds, V1, Vr, V2, Min Manuever speed, Stall Speed etc...Of course speed charts would be necessary to find all the numbers you need... I hope this helps.

Thanks Roman,I' don't have the speed charts covering the alpha so until I get them I'll make a QD :-) but I'll saved your post for future coding :-)BrgdsEugen
