Sort of an odd question, but one I have been fighting here recently. So I still follow the tutorial distributed by PMDG. Yes, I still have yet to master the FMC, but I'm learning more and more as I fly. With respect to the B737-NGX, I noticed last night while flying the Tutorial #1 flight, that my aircraft fails to stay on it's flightpath. I have both LNAV and VNAV active (with autopilot set), but as it approaches turns ion the path, it appears to overcompensate and as a result, when it approaches a straight vector, the plan has to do three or so slight turns to correct the flight vector in relation to the plan vector. With that said, I have come across a few variances between what is in the tutorial and what I get as results in the FMC. The biggest difference are waypoints, but Kyle mentioned to me before that is due to AIRAC cycles, so I try to take that with a grain of salt, but somehow I feel that with those variances, it is messing with the way the aircraft follows the path. My V speeds tend to be more than what is in the tutorial, about +5knts. Trim settings are more as well (those together cause me to have to take more time down the runway). What I really want to know is whether or not it is normal for the NGX to overshoot or overcompensate the flight plan path and what I am witnessing is normal? I tend to believe I may be doing something wrong, I just don't know what it is. As for the other issues, maybe it's the same thing. I will admit fault if it is my fault, I just want to learn this aircraft and learn i correctly. No offense to PMDG, but if they had made any improvements, or if cycles had changed, that they could at least update the tutorial to help out those who are just getting into the NGX now and with the variances coming up, it can be confusing. -Jim
