Also incorporated in the SAS is a stall margin indicator (1), which
receives its signal from the SAS computer. The indicator provides visual
input to the pilot of the ratio of present speed to stall speed for any
airplane configuration. The indicator dial is marked with five color-
coded zones: red (stall), red and black barber pole (stall warning),
yellow (slow), white (30% above stall) and green (speed greater than
30% above stall).
An additional function of the SAS computer is to provide aural warning to
the pilot, through a stall warning horn, of an impending stall condition.
