I have the 777 and I have issues while landing at any airport, what the problem is that I can press LOC but the plane doesnt capture it. I mean I can press the but the plane doesn't follow it. I have everything setup, the ils is set to data and all of the ils freq and course is right. However, it doesnt capture it even though I can press it. 

 

For example, today I was landing at LTBJ 16L and it would show the diamonds on my display and I could press the LOC button but it wont just capture it. This happened at EGLL, CYYZ and all other airports i've been to. I normally vector myself so I go to the beginning of the lines and I am usually at the correct altitude.

Hi Bulent,

 

What does the FMA (top of the PFD) say?

 

Pressing the button is one thing, but the only way to verify what the aircraft is doing -- or expecting to do -- is to read the FMA.

 

Cheers,

I don't know what you have setup.... do you mean you have the FMS programed for the approach?

 

Be sure you fly the Tutorial with this airplane. This will usually answer many questions and introduce you to how the systems work. The Tutorial includes an ILS approach to OMDB for you.

What I mean by set up is that I have chosen my speed and the runway I am landing.

Hello,

As said in the other thread, check the FMA to understand what happens.

 

You say that you vector yourself to the IF, so I guess you must be using HDG mode of the MCP and therefore you must have HDG displayed in green on the FMA for roll mode.

 

What happens when you press LOC? Is LOC displayed in white below the green HDG on the FMA (meaning that it is armed)? If not, then the mode is not armed and the aircraft will never establish on the localizer.

Does it change to green at any time?

Yes sir, basically what happens on the display it shows LOC under heading select in white. But it never turns green when I mean to be turning into finals and such. I heard you're meant to be a certain distance away from the airport but I don't know. 

 

So basically, I CAN press the LOC and which makes it armed but thats it nothing else comes after it.

Hi, Bulent,

 

When you say that you see the "diamonds" are you talking about glideslope and localizer dots on the PFD?  If that's what you mean, does the one for the localizer move to the center when you think you should be turning onto final?  Also, you can put the ND in ILS mode and see if the localizer bar is centered. 

 

A screen shot showing the PFD, including the FMA at the top, ND and the MCP would be very helpful.

Thankfully the LOC worked. I don't know how but it worked. However, I've got another problem but this always happened. At every single airport. I always get the terrain warning and it tells me to pull up. It goes crazy when I am around 50 ft above ground. 

The terrain warnings should be inhibited during an approach, unless the system is not aware that you are making an approach. The status on the PFD looks normal, so I'm not sure what's missing that leads to the warnings.  Are you setting the destination in the FMS? I assume you do but it's a good place to start (ruling out assumptions).

Yes sir I am. What do you mean, Do I have to press Terrain overwrite next to the gear lever when im approaching?

Ah ha... maybe you have not entered the destination in the FMS.

You do not need to override the terrain warning system in normal operation; however, you do need to program the FMS. Have you done that?

 

Good place to start is fly the tutorial. You should not see terrain warnings if you follow the steps, if you do then we have a common ground to work from.

Hi, Bulent,

 

First, on the localizer problem:  there are a number of reasons this could be a problem.  In some cases the older FSX scenery might have a different ILS/LOC frequency or the same frequency you tuned assigned to a different runway than you think.    You might still see an ILS/LOC display on your PFD or ND, but not for the runway you want.  You can check this in the FSX Map function, look at the runway numbers and frequency in the Map window.  The PMDG has much more recent data than original, outdated FSX. At EGLL 27R this should not be a problem as neither the frequencies nor the runway numbers have changed in a long time.

 

Or it could be a setup problem, perhaps landing runway not specified. 

 

Regarding the terrain warnings, there is a l-o-n-g but ultimately not conclusive thread on this issue.  It gets more interesting toward the end:

One thing to try is to go to FSX/PMDG/Navdata folder and delete ARPT_RWY.dat file.  It is not part of the Airac and will be rebuilt the next time you start the PMDG 777.  You can back it up to be on the safe side.  It MIGHT fix this issue. 

 

However as Dan suggested, you need to be sure you have entered the destination airport and runway in the FMC.  In general, it will pay to do the tutorial if you haven't done so.  Otherwise it's easy to leave out something that will cause strange results.
