Haven' t spoken to the engineer yet, so a quick question for you experts:
How does a Universal UNS 1K FMS know the mag variation? Is it taken from a nav database or calculated from gps with input from the flux gate?
The reason I'm asking is, that the FMS now tells us that the local variation is 9deg higher than shown in the charts, resulting in wrong MT and WV.
It is possible to manually input the mag variation in the data pages, but I would prefer to have the problem solved.
Any inputs?
