ABSTRACT
The development of a methodology that will allow the assessment of hazards associated with wake-vortex encounters by fixed and rotary-wing aircraft is presented. The methodology utilizes pilot/vehicle analyses and is intended to serve as a prelude to high-fidelity pilot-in-the-loop flight simulation. The pilot model, itself, has been introduced in the literature for flight simulator fidelity investigations. The analysis procedure provides an economical and time-saving tool for preliminary assessment of wake vortex hazards. The approach is exercised using a model of a small business jet as an in-trail aircraft interacting with a relatively simple vortex model assume generated by a large transport aircraft. Hazard metrics are proposed and employed in the analysis. The possibility of wake vortex-induced upsets providing triggering events for pilot-induced oscillations is emphasized.
