Problem ILS approach

[Rlambert93 0]

In the ngx the ILS approach was working fine I understand I need the ILS frequency for the runway and all that but really can't get it to function on the 777 and capture the glide scope for a automated landing. I know I annoyed a vatsim atc the other day because I couldn't get lined up and he got really annoyed about it which I do understand any help would be great. Like what buttons I should be pressing.

Hi Rlambert93

 

If you don't mind I would join your topic because I have similar issue pretty often. I also have weird issue. When LOC button is armed and 777 is approaching at an angle of about 30-50 degrees (depends on ATC vector), 777 captures LOC and soon after it makes almost 90 degrees turn and fly away from the final. There are times when the aircraft is about to intercept LOC and then she turns away from the final course and keep flying with no logic. It happens very often. I tried to disable all add-on software, just FSX an she still does it. All settings in FMC are normal. So such behavior usually happens on final.  

 

Thanks.

Rob. Read this. I think we (may) have some part of the problem described I that topic.

If you have the ILS tuned correctly then there should be no problem. I find it works perfectly well. However make sure it is the correct ILS frequency, as expected by FSX. The frequency in the navdata is often not the same as the frequency FSX is using (FSX navdata is at least 7 years out of date).  So I always check on the FSX map to see what frequency FSX is expecting for the runway. If it's not the same as the frequency that has been automatically tuned by the FMC you should manually tune with the FSX frequency and inbound course (just enter the frequency and course into the CDU scratchpad and upselect it to the ILS). The format is:

 

NNNN.NN/CRS

 

Where NNN.NN is the ILS frequency and CRS is the inbound course.

 

ATC should not be vectoring you to capture the ILS at more than 30 degrees offset angle, the AP cannot be expected to cope well if they do. If things do go wrong you can always disconnect the AP and fly the approach yourself if visibility is good enough.

I was about to say exactly that.  Thanks!
