Yes, it has been running for years, and for example N11:11 (SAPP Tank temperature in pic) In the N11 data table stays constant at 1300.
But when you look at the data column in the IFE information page the N11:11 value flips to 287 (from N11:16)
then 1573 (from N11:17)
then 1573 (from N11:18)
then 586 (from N11:19)
The value is changing in the data column (white column) but not the data table value....
Could this be caused by a BTW or BTW setup wrong?
