Pilot Variability During Pilot-Induced Oscillation

Pilot Induced Oscillations (PIO) are described as pilot-aircraft dynamic couplings which can lead to instability in an otherwise stable system. Previous and ongoing research has attempted to explain, predict, and avoid such oscillations. In contrast to other research, this effort backs away from pilot models and PIO avoidance and focuses on the characteristics of the pilot before, during, and a...

Analytical Investigation of Helicopter Handling Qualities Criterion Using a Structural Pilot Model

Previous investigations using flight testing and simulator studies have identified influence of vehicle flight speed and control system sensitivity on the bandwidth-phase delay criterion, not accounted for in the proposed new handling qualities criteria for rotorcraft (ADS-33C). In this paper, the impact of flight speed and control system sensitivity on handling qualities as depicted by the ban...

Handling Qualities Evaluation of Pilot Tools for Spacecraft Docking in Earth Orbit

A piloted simulation was conducted to study handling qualities for the final phase of spacecraft docking in Earth orbit. Twelve evaluation pilots, including 10 pilot astronauts, provided Cooper-Harper ratings, Task Load Index ratings, and qualitative comments. The piloting task was manual translational control with automatic attitude hold during the final 10 ft of docking approach until the doc...
