I was guest naviguesser on an X-35 last week and encountered a wierd problem with the B&G instruments. The boat had an H2000 Hercules system (I think it was an performance processor but not really sure and I did not have time look att all the boxes) Most things workede but the AWA (and measured WA) behaved in avery strange way. Upwind in light but steady air the AWA showed 16 deg on SB and 23 on Port. I think the values are a bit small but the difference could be a small offset and a bit of wind shear. Downwind however the AWA read 46-50 degrees while sailing att approximately 140 AWA. The vane on the masthead unit is physically pointing in the right direction but the AWA does never read more then 60 deg...Have anyone encountered a similar problem? Any ideas was the cause might be?
