RadAlt Problems Noted?
Quoting me in prior post:
"If a sensor, such as the radio altimeter, is giving you erroneous information, you have the option to disengage its circuit breaker."
Smilin' Ed:
"I don't think anyone ever noticed the RadAlt problems on this or any of the previous eight flights. If they did, I don't think they reported it."

Have you and I been reading the same thread? The radalt going to -8 feet, as reported, will give GPWS "Too Low, Gear", which was reported somewhere on the approach. It also caused the AT retard. It may have cycled between correct and erroneous, causing multiple alerts and warnings; things such as "Too low, flaps." It would also display "-8" on the EADI, probably in a yellow meatball.
Had the crew pulled the Radalt circuit breaker after the first erroneous indication, the AT would not have pulled the throttles back again in the stall recovery.
