AE 426 explores how aircraft move, whether that motion is stable, and how feedback can shape the response. This temporary student-facing edition preserves the official course facts while making the learning path easier to see.

Purpose and preparation
What the course covers
● Official institutional information
Fundamental concepts of flight dynamics and control. Equations of motion for a rigid body aircraft, linearization/small perturbation methods, static and dynamic stability derivatives estimation, longitudinal and lateral motions and an introduction to flight control systems and automatic stabilization, satellite attitude dynamics and control, including torque free motion and attitude control thrusters.
Official prerequisites
AE 222: Introduction to Aerospace Engineering
AE 314: AE Systems and Control
Official course objectives
Explain core atmospheric flight dynamics—reference frames, rigid-body kinematics, and the six-DOF equations of motion.
Estimate and validate static and dynamic stability/control derivatives in nondimensional stability axes.
Quantify and predict aircraft performance from trim and force/moment balance, linking results to performance envelopes.
Analyze the stability of longitudinal and lateral–directional motions using small-perturbation linearized EOM, state-space models, and eigenanalysis.
Design and tune classical feedback controllers via root-locus to meet handling-qualities and robustness targets.
Explain and apply fundamentals of satellite attitude dynamics—attitude kinematics (Euler/quaternions), torque-free motion, and basic stabilization.
Course Learning Outcomes
What you are officially expected to demonstrate
● Exact official CLO wording
CLO1. Derive and linearize the 6-DOF aircraft equations to obtain state-space and transfer-function models.
CLO2. Analyze and evaluate performance and static/dynamic stability using trim and nondimensional stability/control derivatives.
CLO3. Explain and analyze spacecraft attitude kinematics/dynamics (Euler/quaternions) and basic stabilization concepts.
CLO4. Apply MATLAB/Simulink to model, linearize, and validate dynamics.
CLO5. Design and tune classical SISO controllers via root-locus and verify margins against handling-qualities targets.
CLO6. Collaborate responsibly on a team project, uphold ethical practice and professional technical communication.

Forgiveness Policy
AE 426 includes two Major Exams. To provide a fair opportunity to recover from one unusually poor examination performance, the lower of the two Major Exam grades will be dropped when determining the applicable Major Exam contribution to the course grade.
This policy provides an opportunity to demonstrate improvement and mastery while maintaining the academic rigor and learning expectations of AE 426.
One poor Major Exam does not have to define your semester. The second Major provides an opportunity to recover and demonstrate stronger mastery of the course material.

Grade-Threshold Flexibility
The published grade thresholds are the maximum required cutoffs for each letter grade. If overall assessment difficulty or class performance warrants an adjustment, the instructor may lower the grade thresholds at the end of the semester. Published thresholds will not be raised.
This is limited instructor discretion intended to preserve fairness if overall assessment difficulty justifies an adjustment; it is not a guaranteed curve.
