Emerging DoD Requirement for More Realistic Weather in Flight Simulation

M. J. Sieverding / C. W. Stephens / A. E. Kent

This paper explores the history of the requirements and technical approaches of implementing weather simulation into DoD virtual flight simulators, beginning in the late '70s and extending to today's devices. It also assesses the new, emerging requirements for mission rehearsal and networked simulation and their potential for deriving the requirement for more realistic weather simulation fidelity. Commercial (FAA) flight simulator weather modeling requirements will be presented. Authoritative, real-world weather data sources, models, and data types are described. A conceptual design for implementing them in modern flight simulators is presented including visual and sensor displays, as well as its potential impact on improved training. This paper also describes the rules of engagement to incrementally prototype the addition of common, high fidelity weather modeling into high fidelity flight simulators. The prototyping goal is to provide Air Force Distributed Mission Operations (DMO) with a blueprint for achieving improved fidelity and expanded training capability during DMO networked operations. The focus of this paper is on virtual flight simulation applications, but ideas and methods discussed here could be applicable to virtual ground-based simulations as well, especially those that may be networked to virtual flight simulations.
