Why does anyone still use EPR? It's at best redundant, and (as the Potomac dunking shows) problematic.
I don’t know what I have to say to get folks to stop thinking that the B737 accident in Washington DC/Potomac River in 1982 had something to do with blocked PT2 probes or a lack of acceleration. Neither was the cause of the accident. It was a faulty de-icing procedure that unfortunately covered the airplane in water that promptly froze. Due to the ice, the wing was “deformed” and caused an uncontrollable pitch-up from which the crew could not recover.
