I'm trying to figure out how to arm LNAV and VNAV in the Asobo Longitude (with WT G5000) so that FMS and V ALTS gets announced on the FMA in white. I was able to do it once but not again. Here is what I do on lineup: press the TOGA button on the side of the throttle lever then press the AT button on the back of the lever. On the FMA I see TO, TO in green and ALT S in white (also TO in white for the AT). If I arm LNAV (press NAV) then the green TO switches to green FMS. However, once I saw a green TO and white FMS below when arming LNAV but I can't replicate it again. What should be the correct way to do this?

To get FMS in white you need to set it whilst parked, if you are lined up with the runway it will go active (sometimes even on a taxiway), that is assuming you are flying a SID .. .. ..   Generally in the bizjets I have TOGA and AT before I hit the runway, along with any other mode I want armed, as it does nothing until the throttle is advanced all the way anyway. Obviously I don't do the same in the 737 !!!

Thanks for the help. Yes, once I got on the taxi way it got active FMS in green. However, I have question. I had to modify the arrival just as I was already inbound to the initial fix and after selecting the new arrival everything got cleared out from the rest of the flight plan. The new arrival didn't display either. What gives?

Not sure with that, as I've never had it happen - could just be a bug in the aircraft or a limitation of MSFS in how it handles arrivals & NavData...
