I hear you, scoobflight. Reading the description of the FMS training flight in the ERJ V2 manual, specifically paragraphs 2 and 3 from the bottom of page 30, it sounds like I can set the airplane on an intercepting course to a desired waypoint in the flight plan by first steering the airplane with the heading button roughly towards the vector, then displaying the flight plan on the FMS, pressing DIR, pressing the LSK to the left of the waypoint, and pressing NAV on the FGC. Short of trying, tell me if this is right or am I still lost.
