Hi, I’ve tried few times to do a flight with an RNAV approach with the 787 (Heavy Division mod in my case, but I’m pretty sure this is not the problem): no way to make it flying the approach. Doing all the arrival with no probs, as soon as the selected approach begins, LNAV mode still on, ALT HOLD…

RNAV is not implemented yet in the mod, The dev is currently working on a new FMC.
