NAS-wide simulators: Applications and tradeoffs in modeling fidelity

Presents a collection of slides from the author's conference presentation. ⧁ Most applications require simulator enhancements • Development resource requirements are easy to underestimate ⧁ We have used our NAS-wide simulator for a wide variety of applications ⧁ What worked? • Segregating core simulation from decision making • Client-server architecture • Emphasizing execution speed over fine-grain detail • Most studies are first-order what-ifs, not 3
^rd
decimal point • Real-time capability supports HITL simulation • Capturing core set of realism • Physics-based trajectory model • Basic airport and airspace geometry models • Time-based simulation • Inclusion of uncertainties in core architecture • Graphical / visual validation and debugging
