Really enjoying the 747-8! Going through the manuals and tutorials, flying an ILS approach makes perfect sense, however RNAV GPS approaches are giving me some issues, and this doesn't seem to be explained at all in the manuals. I leave the autopilot in LNAV and VNAV modes all throughout the descent, and Im dialing in the MDA in the ALT Selector. however after passing the final altitude restriction at the FAF, the plane is not intercepting the 3.0 degree glidepath, as is indicated in the FMS. Ive tried leaving it in LNAV/VNAV modes, and it just levels off at FAF altitude with no guidance down. I also tried arming APP mode (which I know is for ILS but wanted to give that a shot as well) and that wont arm. Furthermore if I push in the altitude selector with the MDA loaded up, the plane just nose dives in VNAV speed mode. Basically is this plane, and the latest version (2.1.1) capable of flying RNAV approaches beyond just the FAF?

I'm not sure what exactly is going wrong here. I'm using the X-Checklist found in the link below. I've seen plenty of people use this checklist before and have no problems. I've followed all of the preflight procedures leading to engine start, but when I try to start the engines, they don't want to start. X-Checklist https://forums.x-plane.org/index.php?/forums/topic/178771-fixed-the-checklist-file-for-the-updated-xchecklist-ssg-747-800/ Every time I start the engines, once they reach 25% N2 I set the Fuel Control switches to Run. They begin to start up but then die back down to around 25% N2, and then fluctuate up and down every few seconds.

I just bought the E-series and I am having trouble setting up the flight plan I want. Specifically I am unable to add waypoints that aren't related to the STAR or approach. From CYHZ (Halifax) to CYUL (Montreal), I am trying to program in: KELNO Q806 MOWND VLV OMBRE6 I can set up the departure runway and arrival STAR/transition no problem. But before I program the arrival in, I try to add KELNO, I hit RK1, and it just disappears. I have no problem adding it in aircraft with the Garmin 1000 so it seems to me that there might be a problem with this aircraft, or maybe my nav data. Here are the exact steps I take: (Start E170 aircraft at CYHZ) Menu -> Initialize All [RTE] -> Pos Init -> Load All -> RTE CYHZ -> Origin, CYUL -> Dest, Activate [NEXT] -> type "KELNO" -> RK1 Note that "KELNO" disappears and there is no change to the screen nor error message. The same happens if I first try to put "DIRECT" into the LK1 slot. Can you help me troubleshoot this? (I'm new to aircraft with an FMS but I am pretty good with the G1000 so I'm not starting from zero.) Thanks for your help
