Sorry to keep up the questions about thie FMC, but...
After take off, above 400 ft, I select Autopilot and either select LNAV or HDG. So far, so good, B737 flies excellent.
I then clean up the flaps, etc and select N1 with speed set at 220 kts. Again so far so good.
Next part is now becoming a very major problem...
Whenever I select either VNAV, LVLCHG or V/S - the B737 only wants to nose dive into the ground killing me and my passengers. Even when I disconnect the autopilot completely, I have extreme difficulty regaining control.
I have followed the manuals and wlak throughs, etc but cannot get the B737 to stop wanting to nose dive into the ground.
Please keep me sane and help!!!
