The choice of US SFO>US HNL exemplifies the UN/LOCODE format for voyage destinations because it follows the correct representation of two locations using their respective codes. UN/LOCODE (United Nations Code for Trade and Transport Locations) is a system developed to facilitate the identification of specific geographic locations used in international trade and transport.

This code format includes the country code (in this case, US for the United States) and the location identifier (SFO for San Francisco International Airport and HNL for Daniel K. Inouye International Airport in Honolulu). The arrow notation signifies directional movement from one code to the other, indicating a voyage or transport route.

Moreover, the use of US SFO>US HNL specifically denotes the movement from San Francisco to Honolulu, illustrating a clear and direct route that aligns with the structure of voyage destinations reflected in UN/LOCODE. This makes it a proper instance of how such descriptors are utilized in maritime transport documentation and ECDIS systems.
