GYA351 is a single-axis AVCS rate gyro exclusively for controlling an aileron and is capable of handling a dual-servo flaperon. This gyro works even while the air-brake is being operated.

AVCS or Angular Velocity Control System is equivalent to 'heading hold', except that it utilises a gyro sensor that's more accurate and less susceptible to vibration than conventional gyros. It continually sends control signals to the servo, even when the axis is not moving, for extremely low temperature drift and more positive control for hovering and flying in crosswinds. On this gyro, you can switch AVCS on or off when assigned to an auxillary switch.
