Kiwis some models come with a saved plan or flight which is in the flight planner section of FSX. You just go to the load a plan menu in FSX and check the list of saved flights. Load the plan say 727 cold n dark at KXXX, then relocate it using FSX to where you want to go to start.

Second option is to select the model you intend to fly, when it loads relocate it to your desired start up position/place then shut the aeroplane down, turning of the engines and all relevant systems no longer required, switch to external power, or apu or shut the whole thing down including battery. Then save the flight as the Cold n Dark of your choice. Simple.

Cheers and have fun
