I purchased the 737NG software last weekend and I am having problems with the Introductory Flight (Manual Pages 34 onwards). To the best of my knowledge I have followed the text to the letter but on reaching Page 38 and being instructed to enable the Autopilot A things dont work. I have assumed (Autopilot A is the upper LHS A) and then to operate LNAV/VNAV, LNAV works but VNAV does not and an error message appears in the FMC window (VNAV NOT CONNECTED) or similar. I carried on and noticed values shown in the LEGS page(manual page40) have values in the LHS Links not mentioned in the text. Am I to assume that the manual is not all encompassing and that prior knowledge is required? Yours in anticipation JohnT

John - Maybe you should try the tutorial flight by Fred Clausen to start with. It can be found in the avsim library. Search for Fred Clausen and be sure to pick up version 2.Hope it helps,

Am I to assume that the manual is not all encompassingand that prior knowledge is required? I would agree to that assumption. The issue that you are having is VNAV's ENGAGEMENT CRITERIA.
