Hi everybody,
I'm writing here trying to solve an issue with FMC of the 777-300ER in particular.
When I load a route on the FMC, program correctly the INIT REF page and uplink the winds both for FPL and for descend the LEGS page does not show any speed/altitude prediction for the flight. Just the constrains but nothing more. My VNAV is still engageable if I press the button two or three times on the MCP (otherwise the CDU shows VNAV UNAVAILABLE) but still no altitudes. I have also noticed that my CDU blinks rapidly sometimes when this issue happens and in the VNAV page the ECON SPD rapidly changes from magenta to white and back again.
In the end I would like to give you some more details:
-) PMDG 777 with Sp1b, fresh install from zero. No updates from previous versions since I ve bought it few days ago.
-) I use Virtual CDU 777 app for ipad connected with the module version 2.4
-) the problem described here happens not at every flight. It seems to be random but I think I am not doing nothing different.
-) I use PFPX to export both FPL and Winds
-) I use active sky next as wx tool but in the PMDG menu I have set not to create wx file for the PMDG since it comes from PFPX.
Any idea? I have seen some others have experienced the same problem but I did not understand what causesnit and how to definitly solve if.
Thank you
Regards
