So I haven't flown the big jets for a while (737-400 for FS9) but have just started to again since I put together my home cockpit. I use a Seitek radio panel and multi-panel (for auto pilot). I plugged in a flightplan for CYYZ-KBNA and took off and everything seems to be ok. I am wondering if the following is normal or if there is a problem with my equipment:
Flying along heading toward VOR XYZ at freq. 122.5 tuned on my NAV 1 radio (i just made this number up as I don't have the flight plan with me at the moment) My next waypoint is VOR ABC at 125.5 so I set this into NAV 2 and when the time comes to track toward the new VOR I switch 125.5 to the active radio...and the NAV button on the auto pilot is on and the GPS/NAV toggle switch is set on NAV by the way) After tuning the new frequency the plane doesn't turn. To get the plane to turn I had to set the COURSE on the auto pilot to a number which brought the lines on the HSI into alignment. When I did this the plane started tracking the new VOR.....so, just wondering if this is how it supposed to go. If so, then I guess the NAV radio tells you where the VOR is while the COURSE setting takes you there? I used to be big into the flight sim and flew many hours online years ago but I thought that when I flew back then, setting the nav frequency into NAV 1 radio is all that I had to do and the plane would change its course...guess I'm wrong....or there is something wrong with my equipment?
Thanks for your help!!
