Prolly doing something dumb here, watched several tutorials, prolly need to watch them again, but maybe some of you can help me out.
I can’t get the AP to capture LOC and GS. I have a STAR, ILS approach and runway programmed into the flight plan, and the autopilot follows it to the T. At some point the aircraft autotunes to the correct ILS frequency, and I get the blue deviation lines on the HSI. At an opportune time (typically while making the turn to final and making sure to be below or on the glidepath) I hit APR mode on the AP, and LOC and GS appears in white. But that’s it, it never captures LOC and GS.
What did I forget?
Is your CDI source on VOR1? Before or when you turn onto final, make sure to switch it from FMS1 to VOR1.

What are you talking about? What WTG3000? This is the CRJ-700. It’s a Collins system.

I’ll have to double check. When I did the final turn I didn’t have VOR1 as my source, but after a while I recognized my mistake, and switched it to VOR1 (this is when you get the green line on the CDI, correct?), but maybe by that time is was too late…

I mean… It may have been too late to capture GS, but it should have still intercepted the localizer signal provided you had it tuned correctly. What was your lateral deviation looking like once you switched to VOR1? Were you close or way the &&&& somewhere? 
People kept telling me that it would automatically switch, but for some reason mine did not. I had to manually click from FMS to NAV1 as primary navigation source.
Yes, sorry Kaye,
I thought people would recognize “tongue in cheek humor”.
Didn’t mean to offend anyone.
People kept telling you CRJ’s Collins system automatically switches?
Same for me. Perfectly stable on LOC with source NAV1 but when intercepting the glide the aicraft start diving at 3000fpm
I’m not 100% sure what it looked like. But I was pretty much on glide-slope and flying runway heading just because I followed the correct VS until leveling off at 2000 feet, when I was trying to intercept the GS. At the time when I gave up on the autopilot I was about 1 mile from the threshold and on a parallel course about 500 feet offset left from the runway, but far above glide slope. But I’ll have to fly it again and pay more attention to what is happening. Do I have to dial in the correct landing course, or will that be automatically adjusted because the FMS knows the runway heading? I didn’t adjust the course needle, could that be what I missed?
This is one for Asobo. Would highly recommend filling out a ZenDesk bug report for those who encounter the autopilot dive after capturing glideslope. Here is a link to do that.
Sorry Boston,
I was on the wrong thread with that “automatically” post.
I was told that, but it was about the WTG3000, not the CRJ system.
My bad.

The FMS in the CRJ should auto tune the ILS frequency, set the course, and do a NAV to NAV transfer (from GPS nav source to LOC). If it doesn’t, sounds like there may be something there. Of course you have to load the procedure from the FMS DEP/ARR page, arm APR mode, and be within the capture parameters for it to transfer.
You should be in NAV mode and then switch the source to LOC1… then you shouldn’t need to use the course.
Does the Collins auto-switch from FMS to VOR? Hmm… Not sure I have seen that…

Also, if you have VNAV engaged, it will give you VGP instead of GS. Make sure you disengage VNAV before hitting APR when coming in for an ILS approach.
And then be prepared for a nosedive..

Before I forget: I also never got the snowflake and blue donut, and yes I turned VNAV on (not on the AP but on the MFD to receive decent info). What must I do to get the snowflake and blue donut?
I’ve never had to switch and have just landed, almost perfectly, on KBOS ILS 22L without having to do so and followed the ILS glideslope all the way down to about 400ft.
Edit: Oh, I was in a CRJ 550 btw, so it might be worth giving that a bash, just in case there is something not quite right with the 700. Although as The Dude, used a 700 for his videos, it should be good.
