It took me a while, but I finally broke down to hand over $70 for this plane. I'm speechless. The detail and dynamics of this plane are simply outstanding. The HUGS display is a great feature as well. I do have a few questions though, having only owned this plane for a few hours. First, does the altitude hold (on the auto-pilot panel) override the VNAV path? I found a few times during a KLAX-KLAS run that the plane missed it's TOD and some other crossing restrictions; however, I have a feeling it's because the altitude hold restricted it from descending further. Second, does an accidental knock of the joystick override the LNAV. A few times the LNAV popped off, probably by me subconsciously pushing on my joystick.Third, does this plane have a "direct" function? For ex, ATC gives a short cut to a fix that isn't my next fix. Fourth, I've heard of a "descend now/present position" function. Where is this, and how is this applied?I'd appreciate any responses. Thanks and happy holidays.Kyle

Hi Guys, I recently purchased the PMDG 737NGX and I have completed a few flights in it. However, on every flight, I've not been able to land the plane like I should be able to. I've been following LNAV and VNAV throughout the entire flight. My SID and STAR was entered correctly and everything appeared to be running smoothly. I was still on VNAV and LNAV when I was moments away from turning onto final. I had NAV 1 and NAV 2 armed. I engaged VOR LOC just before I turned onto final. The plane began to turn and then successfully lined up with the runway. After it had lined up I engaged APP expecting it to capture the G/S; somehow, I missed the G/S and had to descend manually. Now, I think the reason it is doing this is because I was going to fast. At the point of capturing the G/S I am normally traveling at a steady pace of 150KIAS; this time it was 220KIAS. I had speed brakes fully extended yet it made little difference. So I think the VNAV speeds are too fast and I can't slow down in time for my landing. I've been told that I should allow VNAV to bring the plane down during the initial decent but then descend at my own choice of vertical speed and my own speed input. If this is correct, how shall I slow down during my STAR. I know it's a strange issue but I'm only 14 so I don't have the broadest of knowledge for this complex aircraft. I need recommendations quite urgently if possible. Thank you.
