I personally don't mind the term SLF, as non-aircrew it kind of defines us,we are being conveyed from one part of the world to another i.e. frieght. Could use PAX, fair enough but this is not your run-of-the mill site.
My view is that ALL on the A/C have a stake in the safety of it but up to a point, I am ex RAF, worked on Nimrods, but aviation has moved on, I try to sit where I can see control surfaces (flaps etc.) but leave it to the experts to work things out, the captain.
However, CC could be utilised to confirm pre-takeoff configuration if trained to do so, as this thread has suggested, that would get rid of need for nervous PAX who are "in the know" to alert anyone, including the nervous flier behind or in front of them.
I speak in total ignorance of training procs for CC, but a rudimentary understanding of the ops of the A/C should be included.
No disresepect meant to any posters.
