  The design of Envelope and Pilot-Induced Oscillation (PIO) Protection
Features, and Failure Cases detection and prevention using Active Control
Sidestick (ACS) is a challenging task. While helping the pilot to respect the
envelope limitations also in failure scenarios and, therefore, increasing
mission effectiveness, these features may have a significant impact on the
aircraft's agility. ACS characteristics are investigated in an integrated
environment. A set of effective and flexible control laws based on Incremental
Nonlinear Dynamic Inversion have been developed in a state-of-the-art aircraft
simulation model and coupled with a two-ways communication with the selected
ACS. The model can run in real-time in a fixed-based simulator composed of
representative cockpit and out-of-the-window.
