2 787 issues that are annoying me

Hi everyone hopefully someone will be to help me with 2 issues I’m having

First one is is the aircraft randomly turning off course for no reason what so ever. Happens every 10 mins or once every 3 hours it’s totally random and the controller can be turned off at the time it happens, this happens on the 320nx also

Second issue

This is the second time I’ve flown the 787 and both times when descending towards the final turn towards the runway the auto pilot has completely lost the plot and just steered the aircraft away from the nav line away from the airport and the only way to correct it is to change to manual heading mode and head back towards the airport before intercepting the runway on ils.

Anyone have any ideas how to tame this aircraft to actually fly it down first time

Thanks

Do not fly the 787, but the FMS/AP system in it, is the same one as in the BA 747, and no one is reporting that.
I might get around to trying an RNAV approach in 787 later on to see, if I don’t fly to Joint Base Andrews instead in 737.

I haven’t tried the 747 yet to be fair

The approach thing is really annoying when you’ve managed to get it down nicely to about 5,000 with out over shooting the airport :rofl::rofl:

The randomly turning off course is annoying but doesn’t take much to get back on track

Ok tried but could not get the FMS to take any of the data it needed. It’s some touch screen in RL (hate touch screens), and it did not take anything I tried to input. It should be very close to 747, but, some of the buttons aint got clue. Know if you create route in WM or even Navigraph and import into sim, it may not transition into FMS, just aint sure what to do at this point, someone more versed in this plane needs to help here.
