I’ve flown the same aircraft with and without FMA calling. It can’t catch everything, in that if you have the wrong mode engaged somewhere
but it hasn’t changed, it still might get missed. Overall, it can’t hurt too much (Disclaimer: as a LH pilot I don’t get as much as I would on multi-sector days. I give the FO 10 mode changes on the approach and then that’s it.
)
Problem is not reading it or not. Problems start when the things are done automatically, no matter if you read it aloud
Absolutely. How many times have you caught yourself saying what you expected to see and 99.9% of the time will see...? The human mind works in interesting ways, especially in situations like these.
