Vehicle body axes are defined from the vehicle’s Centre of Gravity (CofG). For aircraft the definition of body axis is given below, the definitions for other vehicle types are similar:

  • x - Pointing towards the nose (the nominal direction of travel)
  • y - (Orthogonal to x ), pointing towards the starboard side (right wing)
  • z - Nominally down

See the SimGEN software user manual for more details.
