Td Racer -
That's why the stall warning is a 'stick shaker', yoke forces go up, etc. An aural alert saying 'low airspeed' may not get through.
I strongly disagree. When the "Low airspeed" aural alert was added to the 737NG software, it then became the prompt to action the stall recovery maneuver. The pilots reaction is exactly as it would be at stick shaker.
If you say "low airspeed" into the ear of a sleeping NG pilot, he'll yell "set max thrust" and his right arm will move forward. Watch your head
