I'm having difficulty with the PSS 777 in VNAV mode. I've set up the FMC completely, confirmed multiple times that the flightplan, Initial Reference, etc are correct, and still the VNAV will not function.
After takeoff, I tried to engage it, and it just held the altitude I was currently flying at, didn't climb, didn't descend. I know of another avid PSS 777 simmer that has had this issue also, so if anyone has any clues or tips to help, I'd appreciate it.
Thanks a lot in advance,
