VBW/VHW/VLM may be input from a current indicator.

Note: Each GPS receiver GPS1, GPS2, and GPS3 calculates VTG/GGA/GLL/ZDA. The output from HDG OUT and NAV OUT ports is one calculated by the GPS1. However, when the GPS1 is defective, the GPS2 replaces it. When both GPS1 and GPS2 are defective, the data calculated by the GPS3 is used.
