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
