10. Systems Engineering Process
Driving Question: How do we design for on-time
autopilot deployment and successful flights?
Analysis and Simulation:
• Plane model (AVL, XFOIL)
• Engine models
• Create flight plans
• Software in the Loop
Risk Mitigation:
• Train pilot in software model
• Verify plane model with R/C piloting
• Prepare flight anomaly responses
