Define the attitude of a rigid body. 2. Describe the following parameterisations for rigid body attitude: quaternions, Euler angles. 3 3. Define static stability. 4. Summarise the main conclusions of static stability analysis in pitch for a conventional aircraft. 4 5. Lateral‐directional dynamics: define the state variables for the lateral‐directional model. 6. With reference to the linearized lateral‐directional dynamics, describe the corresponding modes, in terms of eigenvalue location in the complex plane. 7. Write the roll mode approximation for lateral‐directional dynamics. 5 8. Describe the turn coordination constraint between roll angle and yaw rate. 9. Draw a block diagram for a heading hold control loop autopilot.
