  1. The problem is this. After takeoff and climb to the transition, I turn on autopilot, VNAV and LNAV. And the next thing happens, the climb stops and the plane flies with a roll down. Clicking on MCP (height setting) to go set does not make any changes. If you disable LNAV and the height is typed with a vertical then it goes to climb. In FMC everything is hammered and the trimer is exposed. The flight plan is planned in PFPX. Simulator P3Dv4. And the same happens as in 747 and 777. What is it can be and how to fix it?
  2. Hi Folks! Bought the beautiful F50 a couple of days ago, I'm still puzzled as how to operate it properly though. Did my first flight today, EBAW-EGLC. Everything went well up until I was in the air and turned on the LNAV. I noticed that the aircraft became very unstable, rocking from one side to another trying to maintain the course. The F50 even took a couple of dives, while I set the ASEL and VS at 1000 ft. This "rocking" remained the entire flight, although the aircraft seemed to be more stable once reaching cruise altitude. Same story while descending, the aircraft violently rolls from one side to the other. Not sure what I'm doing wrong here? Autopilot seems to be set up properly (LNAV/ASEL/VS/AP Engage). Thanks! PS: What's the difference between NAV and VAPP? Which one do I use for the ILS APP?
  3. 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
  4. 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.
  5. Today I encountered the following strange behaviour (tried two times,both same bahaviour, one time with AS4, second time without AS4): approach to LEMG to ILS Z 12 via PIMOS1DCQ arrival - inbound D011S everything normal, LNAV, VNAV PTH and HOLD - as soon as reaching D011S (why does she not turn before reaching -is it a must overfly wpt?) suddenly AT announces THR and the vertical path jumps to almost 2000 ft above.. - ca.20 seconds later again HOLD is announced (but I have to pull back the throttles of course) and vertical path is 450 ft above - then for ca. 2 minutes AT stays in HOLD letting rise the verical path without attemptimg to recover. then finally SPD announced and VP recovered Later on the vertical Path jumped up and done significantly two times more.... Also the other day approaching LGAV via KEA I had the vertical path jumping 8000 FT down suddenly, so decent was obviously started way too late....(But I cant get details for that right now as it takes too much time) So whats going on here...?? Is it me doing something wrong? Hopefully but I honestly dont think so...
  6. Hello everyone, I am having an autopilot issue with my QOTS II . I encountered this problem since my first flight with the autopilot system. I set my route as usual following all the procedure. Also, I have already switch on FD then LNAV and VNAV on ground before takeoff. But as soon as I was airborne, I switch on the Left autopilot as it immediately show VNAV ALT and autopilot disengaged. I try to switch to center and right autopilot and the same problem happened again. Here is a screenshot of the problem.
