I am familiar with the thys at ams.
the animation says it all.
I get mad at myself if I get 5 knots slow. I mean really mad and it doesn't happen often. But this pilot got 34 knots slow. animation is interesting, esp that after full power they accelerated by 2 knots!
dear race car driver. a pilot can perceive speed in many ways, the airspeed indicator is the most important. but sometimes your eyes are not on the airspeed indicator (SHAME ON THEM). There is a gadget called a stick shaker which physically shakes the control wheel to WAKE UP a pilot. Stick shaker at the least should make you LOOK AT THE AIRSPEED INDICATOR and add thrust unless the stick shaker has fired off in error. It is an electric motor mounted eccentrically to vibrate things to wake you up.
In older planes the controls would shake and you would feel it, but with computers and hydraulics between the wheel and the controls something artificial had to be added.
Clearly, these pilots were not top of their class.
