ENGINE START SWITCHES PMDG 738

Post by Skycowboy »

Hej,

after Engine start procedure my ENG START switches turn to off about 56%N2 automatically - ok! But, it dosn't switch a little bit to weak half a way, only.
Are there a value in the script, which I could change in order to get more "power" to move the switch?

Best regards
Rolf

Check this OC4BAv5 topic viewtopic.php?t=991

It should be the same in the PMDG737 driver for MSFS script.

Hej,
thank you)

I reduced the ENG1 and ENG2_Servo value from 800 --> 200 and the ENG START_SW switching with normal power and speed to off!
Var 1220, name ENG1_ST_SW_POS, static // servo arm is set to free, value 512, when driver starts
{
IF &sENG1_S_GRD = 1
{
IF &ENG1_ST_SW_POS = 1 // if in GRD and receive OFF from ngx
{
&ENG1_Servo = 200 // Auto off phase I to trigger servo arm to kick to OFF - The Power to switch off increase by reduce value 800->200
&ENG1_Servo = DELAY 300,200 // Auto off phase II should reset release servo arm to free
}
}
}


Best regards

Thanks for sharing.

As the servo installation either in an own built module or an Opencockpits factory built module is not 100% identically installed, the user must make some changes to the default script as it is impossible to make a ONE script that fits all.
