For YASim Piston Prop aircraft, two properties need to be set to have an engine running on startup: | |||
* <code>/engines/engine[0]/rpm=1000</code> | |||
* <code>/controls/engines/engine[0]/magnetos=3</code> | |||
This ensures the engine is turning sufficiently quickly and the magnetos are switched on. You may also want to ensure you have any fuel taps on. | |||
By default, YASim will attempt to set the gear state (<code>/control/gear/gear-down</code>) depending on whether the aircraft is on the ground or in the air. To over-ride this behaviour and ensure that whatever you set in the overlay file is respected, set <code>/fdm/yasim/respect-external-gear-state=true</code>. | By default, YASim will attempt to set the gear state (<code>/control/gear/gear-down</code>) depending on whether the aircraft is on the ground or in the air.
