This latch has been designed from experience with similar airplane fittings. Under way, the latch is self-energizing, locking harder as the pressure on the pendulum increases. The result is greater power and sensitivity. Friction will affect the performance of any vane gear in a very negative manner, particularly in light airs. The result is completely smooth connection between the vane and the pendulum.
Any control system needs a feedback mechanism to prevent it from overreacting.
Both provide split second disengagement of the self-steering gear. The small wheel adapter is designed for mounting on the inside of the steering wheel where it is out of the way and hardly noticeable, but can be adapted to outside mounting. Normally it is on the front of the wheel, between the wheel and the pedestal. It is engaged and disengaged with a vertical clutch pin. You normally lead both lines to the same side, either starboard or port.
