In the case these commands lead to instabilities, the phenomenon is then called Pilot-Assisted (or Augmented) Oscillations (PAO). This is a complex phenomenon that depends on three basic elements. First element is the aeroelastic modes of the aircraft, especially their modal shapes (since only speci\ufb01c modal shapes interfere in this phenomenon) and frequencies. Second one is the inceptor\u2019s system characteristics, such as natural frequency and damping. The last element is the human pilot dynamics, which may be modelled as a passive spring-mass-damper system. This paper aims to explore how these three elements affect the development of the PAO phenomenon for more \ufb02exible aircraft. The investigations herein are accomplished for a virtual, \ufb02exible aircraft by the analysis of pilot-in-the-loop simulations of a high gain maneuver, varying airframe elasticity levels, inceptor system parameters and pilot model characteristics.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/02\/IFASD-2019-061.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Daniel Drewiacki, Flavio J.
