Professor Zalewski participated in the works of the working group for navigation supervised by Mr. Siu Man Chung (Hong Kong, China) within the scope of points 2), 3), 4), 6), 8) and 12). One of the most significant effects of the works during the sixth session of the NCSR Sub-Committee was the establishment of the guidelines for the S-Mode, which were handed over to the 101th session of the Maritime Safety Committee (MSC) with a view to their approval. The adopted name of the guidelines is “Guidelines for the standardization of user interface design for navigation equipment”, but they will still informally be known as the “S-Mode Guidelines”. Professor Zalewski, who participated in formulation of the guidelines through a correspondence group established in 2018 under the supervision of Mr Nick Lemon from Australia, during the session, was in charge of a group responsible for correction of the circular SN.1/Circ.243/Rev.1 concerning guidelines for presentation of symbols, terms and abbreviations related to navigation.
