- /** Retrieves a body frame angular acceleration component.
- Retrieves a body frame angular acceleration component. The angular
- acceleration returned is extracted from the vPQRdot vector (an
- FGColumnVector). The vector for the angular acceleration in Body frame
- is organized (Pdot, Qdot, Rdot). The vector is 1-based. In other words,
- GetPQRdot(1) returns Pdot (roll acceleration). Various convenience
- enumerators are defined in FGJSBBase. The relevant enumerators for the
- angular acceleration returned by this call are, eP=1, eQ=2, eR=3.
- units rad/sec^2
- @param axis the index of the angular acceleration component desired (1-based).
- @return The body frame angular acceleration component.
