December return of the -8 or -9 is overly optimistic (my personal opinion). The FSB report, which outlines new pilot training requirements, is still in draft and just closed to public comments 11/2. It will take some time for FAA to adjudicate all the comments and finalize the FSB report. After that, airline training programs will have to be revised and approved. Then additional pilot Differences training (NG to Max) can begin. Not to mention all the Airworthiness - AD requirements for RTS. For the future -10, I would hypothesize (3) AOA vanes may be standard equippage.
