Hello!

When you start a Simjet, you will have to set the throttle range first. On idle the yellow light must be steady with a flashing green light. Then move the throttlestick to max and adjust your endpoint until the yellow light comes on. Then move your stick back to idle position and after a second or two the start sequense will come to live. The red light will go on flashing, it tells you to open up the gas supply and when the gas ignite the red light will be solid when the combustionchamber is hot enough. Then it will start the fuelramp and then the engine should be running on its own after a few second.
