That answers all my questions and reassures me on the use of the system.
The four pages of technical stuff in the link you provided catapulted me back a few decades ago, the F104 Starfighter and Swearingen Merlin III were by design aircraft that heavily relied upon SAS systems and flying without was a very unpleasant experience that quickly could get out of hand and even cause loss of control.
