Abstract :
The Global Positioning System provides 3-D position that can be used for aircraft precision approach worldwide. Autopilots can be designed to optimally use differential GPS while minimizing risk to user safety. A failure probability model of GPS uncertainty is constructed to evaluate aircraft controllers by simulation. Simulated annealing then searches for the gains that minimize accident risk, demonstrating that simulation-based optimization can make real-world controllers more robust
