Hi all,
Where can we find a tutorial for the CS777. I own and operate well the PDMG 737 series and the LD767. I thought when I purchased the CS777 that I would be reasonably able to operate it.  Programming the FMS is easy. Take-off is also easy. However, it seems that I can't keep climbing after I switch AP and VNAV. Aircraft begins slowly descending. To keep climbing, I must use VS/FPA and adjust the climb rate.  What do I forget or do wrong with this aircraft? Thanks

There is no tutorial for the 777.

If you know how to operate those other FMS's, then you are doing it right for the 777. However. There is a serious bug with VNAV, so to do a climb, it's best to use FL CH up to cruise altitude.

Sometimes I get lucky and VNAV works correctly, but most times it doesn't. Captain Sim are working hard on an update that will address this problem.
