Nomad,
In a companion thread here there is discussion about having to rely upon the same faulty sensors even in "Manual" reversion and comments that one might actually be in "pseudo-manual mode" as a result.
I think back to the long discussion about AF 447 crash and the circumstances surrounding that tragedy.
How does a crew really get back to an old fashioned "Hands On" configuration of controls, instruments, and sensors (where all of the automation and fancy gadgets are completely isolated from involvement) these days?
