All positions specified are in metres (which is weird, since all other units in the file are English). The X axis points forward, Y is left, and Z is up. Take your right hand, and hold it like a gun. Your first and second fingers are the X and Y axes, and your upwards-pointing thumb is the Z. This is slightly different from the coordinate system used by [[JSBSim]]. Sorry. The origin can be placed anywhere, so long as you are consistent. I use the nose of the aircraft. | All positions specified are in metres (which is weird, since all other units in the file are English). The X axis points forward, Y is left, and Z is up.

(In the [JSBSim_Aerodynamics#Frames|JSBSim coordinate system], X and Z are the same as in YASim, but Y points to the right instead of left.) | |||
