Problem on second approach RNAV PMDG777

[Plum130992]

Hello,

I'm having a problem with the second LFRS RNAV21 approach with the PMDG777.
I program a vector approach (heading) to intercept the IRS21 point, then LNAV, VNAV. The first approach works fine.
But, after landing, when I run the scenario again, whichever way I do it, FSIPanel positions the aircraft in the right place, but programs an ILS03 approach in the FMC instead of RNAV21.
The approach can then be reprogrammed manually in the FMC, but the VNAV mode no longer handles the descent.

Hi,

I think the FMC is not set properly on 2nd approach, please have a look at this:

Hello Jean-Pierre,

Thank you for this very instructive video. The final descent problem has been solved.

However, I don't understand the logic behind programming the approach on the FMC (DEP/ARR page). In fact, while I'm specifying an approach on runway LFRS/21, the FMC is programmed by FSIPanel on the ILS03... (not always).

Regards,

The logic is very complex because I cannot read Fenix MCDU...
I'm just assuming where we are and what to type without having a view on it
Most of the time it works but depending on previous entries or old database, it can fail.

In this case, it's not the Fenix, but the 777 PMDG.
Sorry but, I request an approach on runway 21, the aircraft is correctly positioned for the approach to runway 21. So,I don't understand why the FMC is programmed for an opposite approach, on runway 03 !?
