The FAA needs to bump the age up to 68, certify certain AMEs the ability to certify over 65 yo pilots, sort of like a special issuance. Restrict to right seat ops, this will be a great tool for the Professional Pilot and Mentoring programs mandated by the FAA and of course you still must pass your annual company checks. Questioning the cognitive skills of a 68 yo shouldnt be the issue when United almost put a 777 in the drink with a brand new CA and FO. Ill take my chances with the old dude, its getting scary out here with the stories being told about new hires and rapid upgrades.
