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

acceleration or deceleration. For any constant rate of acceleration or deceleration, the moving end of the line
