Refer to the Airplane Flight Manual (AFM) for speed criteria and Vspeed values.

The Airspeed Indicator displays airspeed on a moving tape rolling number gauge. The numeric labels and

major tick marks on the moving tape represent intervals of 10 knots. The minor tick marks on the moving tape
represent intervals of five knots. Speed indication starts at 20 knots, with 80 knots of airspeed scale viewable at
any time.  The indicated airspeed is displayed inside the black pointer. The pointer remains black until reaching
maximum operating speed (V

MO

/M

MO

), at which point it turns red along with the Mach number readout.

The Mach number is displayed below the Airspeed Indicator (Figure 2-3) for airspeeds at or above Mach 0.4

or at altitudes above 28,007 feet. The color of the readout is the same as the color of the airspeed pointer.

Speeds above the maximum operating speed, V

MO

 or M

MO

 depending on aircraft altitude, appear in the high 

speed awareness range, shown on the airspeed tape by a red/white barber pole. An aural overspeed warning
tone is generated if the airspeed exceeds the high airspeed limit.

Yellow and red ranges are also present for low speed awareness velocity (V

LSA

).  If the indicated airspeed is 

within the yellow range, the airspeed readout is displayed in yellow.  If the indicated airspeed is within the red 
range, the airspeed pointer is displayed in red. An aural stall warning is generated if the airspeed falls below
V

LSA

. An open green circle on the airspeed tape represents 1.3V

S1

.  The green circle is displayed when in the air 

below 18,000 feet, and it indicates the stall warning system is functioning correctly.

The Airspeed Trend Vector is a vertical magenta line that appears to the right of the color-coded speed range 

strip when airspeed is either accelerating or decelerating.  One end of the magenta line is anchored to the 
tip of the airspeed pointer while the other end moves continuously up or down corresponding to the rate of 
acceleration or deceleration.  For any constant rate of acceleration or deceleration, the moving end of the line
