The association of the space frame and the time frame constitutes a frame of reference. In physics, a Galilean or inertial frame of reference is a frame in which an isolated object is in uniform rectilinear translational movement: the speed of the body is constant in direction and in norm. This chapter defines the aircraft trihedron, or Lilienthal axis system. The aerodynamic speed trihedron of the aircraft is defined as, the trihedron has an origin G, which is the center of gravity of the aircraft. The coefficients on tracks y and z are restored in an aircraft trihedron demodulated of the aerodynamic roll. The balance trihedron is defined as, the trihedron has an origin G, which is the center of measurement of the balance. The reference trihedron is the local geographic trihedron defined at the point of projection of the aircraft on the launch ramp.
