Perhaps those like me that want to go through a normal start up and check list, especially in AC that I fly often and know well, can use Melchior's ac_state.nas to accomplish this goal at airports we often fly from. It should be easy to add to the check for state == 0 and in that case start with the engine running in take-off configuration (meaning all the items in the take off check list are set to nominal safe values). I don't think ac_state.nas is in cvs. I am attaching a tarball copy. This will require changes to the AC files and perhaps addition to ac_state.nas which goes in data/Nasal. I have used ac_state.nas to create pa24-250 files for KLMO (home airport) and KBTL (sisters airport). By renaming state files, fgfs launches with N7764P in a parking area I chose with every switch, mixture, etc. as it was when I parked it and shut it down. Frankly, if you take off from KLMO (Longmont, CO, N7764P home airport) or KEIK (Eire, CO) or much worse from KEGE (Eagle County, CO, elevation) with the mixture full rich, you may not clear obstacles and for sure will use much more of the runway. In fact a guy from Texas crashed his Cardinal, killing his family, departing from KEIK w/o leaning for take off. So it is not possible to achieve safe nominal values that work for all fgfs airports.
