Using piloted simulation to measure pilot workload of landing a helicopter on a small ship [PDF]
, 2017 When conducting landings to a ship's deck in strong winds, helicopter pilot workload is often dominated by the turbulence within the ship's airwake. Previous studies have shown that larger ships create more aggressive airwakes and simulated flight trials
