I have been trying to understand how to use the G1000 autopilot. I’ve learned how to set a flight plan and load the approach I want. I’ve also set the Nav1 radio correctly. I’ve successfully captured the GS on a few different approaches.
One tone I notice occurs extremely close to the runway. If I’m not mistaken, this one is a series of beeps (maybe four or five). I’m not exactly sure what this tone means, but I’m thinking it is an alert that if you don’t see the runway now, you should go around.
My real question relates to a flight I did yesterday. Flying into KBNA runway 31. I had 111.95 on Nav1, was flying at 2600ft when I crossed HOLER. The glideslope indicator crossed my current altitude, but the plane didn’t follow it and a constant tone started blaring. Any idea what that tone would mean and/or what I might have done wrong? Maybe it has something to do with the RADAR note I see on the chart…?
