Why no glideslope capture?
-
This has happened on the last couple of flights I've made in MSFS 2020. The plane is all set up for an ILS approach. APP mode is activated. The localizer and glideslope indicators are both alive, the localizer has been captured and I'm well below the glideslope. The CRS is selected to V/L. The glideslope indicator descends to the point where the autopilot should start to descend, but it just maintains whatever altitude it was at. I have to activate VS on the autopilot to descend. What could be causing this? Thanks.

Can you confirm that you had a white GS indication on the PFD prior to the descent point on the glideslope?
You should first get a white GS indication.
When the glideslope is captured, you will get a green GS.Also, on what airports and runways did you encounter this?

I believe it was KBIS R31. No, I didn't see the white GS indication. Why would that be, since the glideslope indicator was present and moving down? I saw in the manual that we're supposed to engage V/L mode on the autopilot to capture the localizer, and then engage APP mode to capture the glideslope. If I engage APP mode without having engaged V/L mode first, would that cause this problem?

I do the following:
- I press VORLOC on the MCP when on an intercept heading. I also select V/L as primary course on the ND and LNAV as secondary course.
- Confirm LOC white.
- When I get a green LOC (localizer capture) I press APP on the MCP.
- Confirm GS white.
Usually I try to get a level flight segment on the intermediate segment (established on the localizer and below glideslope), which means I have a green ALT on the PFD until the GS mode takes over.
Haven't had any problems with it using this method. -
Using V/L on the MCP prior to APP seemed to do the trick. Looks like I may learn to fly this thing after all.
