The revoking of the RPN-AR certification is the way for EASA to allow the 737 MAX back to service with two sensors while Boeing gets time to do the software changes to create a third, synthetic sensor. While adding a version of EICAS may be a very sensible thing to do, I completely understand why Boeing don't want to spend time/money on further changes to the MAX, or open the door to retro-fitting anything to the NG series. That would necessitate MCAS being described in the Flight manual, and possible additional training for Pilots, and since the Boeing management dictate at the moment was "no additional training" at any cost, someone elected to change the face plate text description on the Cutout switches and rewire them in series. ./cache/leehamnews-com-8105.html ./txt/leehamnews-com-8105.txt
