Aircraft simulation validation using an instrumental variable approach
… developed which offers the potential to validate aircraft simulation models using noisy flight test measurements. The proposed validation procedure is based on the instrumental variable parameter identification method. The instrumental variable method requires a choice of "instruments." For this …

Methodology for the validation of aircraft simulations in a mission scenario through the use of a validation tree with uncertainty
… uses probabilistic analysis and computational simulation to continually update the state of a fleet of aircraft. This methodology describes a process in which the aircraft that is most likely to successfully complete a mission is determined computationally, and after the mission, computational …
