The unlikely case of both rad alts giving an incorrect height and causing the aircraft to go to idle power and flare, but at the wrong height (mentioned a few posts ago) when on approach was covered by an OEB issued after the Turkish 737 crash at Sciphol. It is still valid and requires immediate disconnection of autothrust to avoid a stall. Although technically in normal law, I am not sure how normal law alters when FLARE mode (NOT the flare law pitch down 2 degrees/8 secs) is activated by the autopilot?
The FCOM says that A of A protection takes priority over other protections so if an overspeed was also indicated, one would expect the stall prot to work? or would normal law degrade?
