Except in my airline, where using FMS for primary nav below MSA is forbidden.
You have to follow the needle otherwise you can't call established. If the FMS says you are a mile off track but the ADF is on track which is right? Who knows? Our FMS is BRNAV so it must be within 5nm 95% of the time. That could be worse than the ADF. Don't expect a straight approach every time with an NDB but do expect to be able to position the aircraft for a decent landing if visual at minima.
Just think, if you disregarded the needle, followed the FMS, flew down to 300ft MDA where you shouldn't be, got EGPWS warnings, and then at the investigation said "well I disregarded procedure and followed the FMS rather than the appropriate nav aid because I don't like NDBs then you wouldn't have a leg to stand on. FMS may be the norm but it isn't perfect.
