VGP mode when selecting APPR on an ILS?


Recommended Posts

Hello,

 

I've had this happen a few times now. When I'm on a heading to intercept the localizer I press APPR mode but instead of getting LOC1 and GS armed I get HDG and VGP as active modes. The LOC and GS do not arm. I don't remember each time it has happened but I do remember that it happened on the ILS 27 into KCVG and the ILS 33L into CYYZ.

 

For clarification, the correct localizer frequency is in and the approach is pulled from the FMS. I understand that VGP is a VNAV mode and each time this has happened I've been using coupled VNAV for the descent.

 

As a work around when this happens I've been using NAV mode and just tracking the localizer. Then I use VS mode to keep the plane on the GS. It works, but isn't exactly what I want to be doing.

 

Any suggestions?

If you moved into HDG Mode you may have deviated from the standard Approach...  If the NAV source is still on the FMS it might not auto sequence ...  also if you are still in VNAV that might be weird since you would want to do ALT Hold at the intercept altitude and Heading mode for your vector....   So that that point you would be able to change the NAV source to VOR/LOC 1 and then use APPR Mode....

Are you receiving signal from both LOC and G/S at the time you press APR?

 

Yep. With the blue preview needles visible before switching to green needles.

Nav source is green needles. ALTS mode is active. I flew the CRJ-200 for years in the real world so I promise you I know how to fly an ILS approach. I don't mean that to sound condescending. I appreciate your help. I only mention it to eliminate concerns about not having things set up correctly. Although I'm certainly not immune to brain farts!

It's weird one because it's not something we have seen on our tests that the VGP mode activates instead of the GS. But we'll keep eyes open if we can recreate it. Also if it happens to you again, please take a screenshot of the PFD (or even better video).

I have just seen this behaviour.

 

Approaching EGHQ, ILS 110.5, (RW12,) tuned both sides. Select Appr and I see HDG VGP. ILS (LOC and GS dont arm). This after a full flight from EGNT using flight plan from SimBrief.

 

I tried again, just doing a take off and circuit from EGHQ and everyhting worked normally! Selected Appr and got LOC1 + GS.

 

So it appears to be an intermittant bug?

 

Ive even gone back to the initial install 1.0.0.0 to try to determine if the CRJ update did something?

 

Still intermittant bug in both 1.0.0.0 and 1.0.01.

 

I think its an Asobo bug. Ive been flying the CRJ for years in P3d and have no issues!

 

Thanks.
