Engine Starting

Recommended Posts

Guest pscarratt

Hi,Can anyone help me with using the (>K:TOGGLE_STARTER1) event to start a jet engine. Is there something else I need to set aswell? Using this command on its own seems to do nothing?Any help would be much appreciated!

That will only set the starter in motion, but a jet engine also needs fuel and ignition sparks to get started. So you also have to set KEY_MIXTURE1_SET to more than 164 which should light the fire when sufficient N1 RPM is attained by the starter.

Thanks Mathias but when I toggle the starter i don't even seem to get any engine rotation at all? Any ideas?

Try another starter-related key event.KEY_MAGNETO1_STARTworks on my true FS2004 turboprop because I also found the normal key event you use did not work as expected.

Hi Paul,You have to keep repeating the Toggle event in your code untill the enigine is running (N2 greater then a certain value, e.g 50%).One Toggle event by itself does nothing ..So, like: (G:Var1) (A:Eng1 N2 RPM, percent) 50 < && if{ 0 (>K:TOGGLE_STARTER1) } els{ 0 (>G:Var1) } Start Engine-11 (>G:Var1)Or (manual repeat by the user):Start Engine-1 (Keep depressed until Engine running)0 (>K:TOGGLE_STARTER1)Cheers, Rob Barendregt

Alsowhatever button on the joystick-external interface is assigned to starter 1, make sure you have the "repeat" set in the assignments area of the sim itself. Otherwise it acts as a momentary switch.Steve

I've actually used a butchered version of that used in the default 747 with some of my own variables added in....(G:Var1) if{ (L:ENG1 START POSSIBLE, bool) 1 == (A:ENG1 N2 RPM, percent) 50 < && if{ 0 (>K:TOGGLE_STARTER1) } els{ (G:Var1) -- (>G:Var1) } } (G:Var1) 0 != (A:GENERAL ENG1 STARTER, bool) || if{ (L:ENG1 STARTER KNOB, number) } els{ (A:ENG1 N2 RPM, percent) 35 > if{ 0 } els{ 0 } }Eng1 Starter Knob GND5 (>G:Var1) -1 (>L:ENG1 STARTER KNOB, number)Eng1 Starter Knob Cont5 (>G:Var1) 1 (>L:ENG1 STARTER KNOB, number)Eng1 Starter Knob Flt5 (>G:Var1) 2 (>L:ENG1 STARTER KNOB, number)The code is for a three way starter switch like in the 737. The (L:ENG1 STARTER KNOB, number) variable is used to allow me to keep the switch in the right position until the engine starts.Cheers,
