  Hamid,
  
  Yes.
  And we might add that airspeed itself is a secondary indication ... of the
wing's AOA ... and valid only for 1G.  A glance at an external, isolated AOA
vane is checking the basic cause of stall: the ANGLE at which the relative
wind breaks away from the top of the wing.
  If everything else goes to hell, you only need a needle-ball equivalnet and
an AOA to fly the plane -- or glider -- or plane that has become a glider.

   If you even remember to look at the attitude indicator, it is showing a
normal attitude (early on in the event), or a nose low attitude (later in the
event), or a very nose low attitude (very late in the event).  What does it
mean?  It does not jive with what you are focused on and believe to be your
immediate problem, an imminent or developed stall.  Oh, by the way there is an
alarm still going on about the airspeed.  The altitude is rapidly decreasing,
the airspeed is continuing to decrease and the decrease is correlated by a
decreasing ground speed (when you are in a steep dive, there is little
movement across the ground).  And the airspeed alarm is still going on.  At
that point, can you reboot your brain and start diagnosing the problem from
scratch?  All while the low airspeed alarm is going off.
