Define the direction cosine matrix for rigid body attitude. 2. Describe the axis/angle parameterisation for rigid body attitude and its relation to the quaternion one. 3 3. Define body axes, stability axes and wind axes. 4. Longitudinal dynamics: define the state variables a nd the control variables for the longitudinal model. 4 5. Define the most significant aerodynamic derivative for longitudinal dynamics. 6. With reference to the linearized longitudinal dynamics, describe the corresponding modes, in terms of eigenvalue location in the complex plane. 5 7. Write the short period approximation for longitudinal dynamics. 8. Describe the turn coordination constraint between roll angle and yaw rate.
