Ship-based rotorcraft are often required to operate in turbulent, unsteady flow fields. The interaction of the rotor and rotor wake with the turbulent airwake can cause uncommanded aircraft motion and high pilot workload. This paper presents a simulation-based handling qualities assessment of a robust adaptive gust compensating control law for rotorcraft. The control law is designed to improve command tracking and disturbance rejection when operating in an airwake. Details of the simulation implementation and experimental setup are presented. Piloted simulation evaluations were performed by three active-duty, experimental test pilots. Handling quality ratings and pilot activity were analyzed. Results indicate the controller's ability to reduce pilot input activity and improve handling qualities ratings by two points on average.

“…It is possible to build highly automated systems (modern aircraft illustrate this); it is possible to build adaptive systems (see for example [19]), and to address some of the other subproblems such as illustrated by IBM's Watson playing Jeopardy [20]. Because of these (in some cases hugely impressive) successes and (perhaps) a belief in technological progress and prowess, there are those that believe automation is the answer; these we have characterised as the Pollyannas who are relentlessly positive about what can be achieved.…”

The terms Pollyanna and Chicken Little are used as caricatures for those who are relentlessly positive and those who, in contrast, see problems in everything. Many opinions about automation in aviation tend to reflect these contrasting viewpoints. In this paper we propose the introduction of an ethical safety case as a means to reconcile these views by clearly articulating ethical issues involved in automation.
