It covers a wide range of activities carried out by Engineering and Flight Line teams, both in the areas of calculation analyses and as a result of simulation studies, flight and ground tests. The document covers findings of two projects, in which the SW-4 SOLO helicopter took part. One of them is the OCEAN2020 Project, in particular the part concerning the HELIMARIS stage with helicopter modification for the needs of over water operational capabilities. The other is the RPAS In Air Project, where the main configuration changes were the innovative implementation of the system for satellite communication, and a series of tests demonstrating the possibility of controlling an unmanned aerial vehicle with the use of a satellite data link. Over water operations include cooperation with vessels, which was facilitated in the present research project using the T-23 class corvette. Numerical analyses presented in the paper, followed by simulator and flight test campaigns, ensured that the performance objectives of the system were met, as well as compliance with the safety objectives required by authorities. In particular, flight mechanics of the platform were positively evaluated in terms of control margins, stability, and time response in the case of Emergency Floatation System (EFS) malfunction. Different Automatic Flight Control System (AFCS) settings and pilot delay times were examined, and conclusions for further system developments were stated.
