Why is it important to be sure that there is no air in the telemotor system of the steering gear?

Oh, dude, making sure there's no air in the telemotor system of the steering gear is crucial because air bubbles can mess up the hydraulic fluid flow, causing erratic steering and potentially leading to a Titanic situation. Like, you don't want your ship going all "I'm the king of the world" on you when you're just trying to dock. So, yeah, getting rid of air bubbles is like steering gear 101 for smooth sailing.
