Hey, guys.  I've had a problem lately coordinating the FSX default ATC flight plans with the flight plans I load into the CS 767 and 757, particularly the arrival paths.  It's gotten to the point where I don't bother using a STAR, rather I fly direct to the ILS point for my arrival runway (assigned by ATC).  To get to that point, I have to disengage LNAV and VNAV and fly with the heading select and altitude hold functions until ATC clears me for the ILS approach.  Then, when I attempt to engage the localizer hold, the aircraft won't lock on. Any tips?  I apologize if I am confusing, I can't very well understand either.

FWIW; There are several things that can cause a bad lock-on. If you're approaching the localizer by more than a 3 degree angle, if the attitude  of the plane is nose-up or down more than 3 degrees, and if your AGL altitude is too high, (important when it comes to FSX's POV), you may not get a lock.

For the FSX altitude 'thing', I started setting the plane to 2100 feet AGL everytime I do an ILS approach. It seems to keep FSX happy because since I've started doing that, it'll always 'see' me.

But then again, that's what I do for the Glide Slope catch. Still, I'm usually within 800' to 1000' of the 2100' AGL mark when I enter the localizer range.

So you may want to check that and of course, please disregard if you have.

You should not need to dial in the ILS frequency, it is added to the NAV/RAD page of the CDU upon selection of the arrival runway.

If by chance you need to add it manually, you can dial it into the ILS Tuner on the Aft Pedestal. Do not enter it in the VOR Tuners (on the Glareshield) as they are not used for APP by the MCP (AP).
The format for adding the ILS frequency/heading to the NAV/RAD page of the CDU is XXX.XX/XXX (i.e. 110.10\343) in LSK4L.

In my image below, I selected ILS34R as the arrival runway, and the frequency/heading were automatically added to the NAV/RAD page of the CDU and to the ILS Tuner on the aft pedestal.

Under certain "missing T/D" or the "missing end of the route" problems, I always select the ILS Runway, then, if needed, I'll simply select the runway without any preceding info (RNAV, ILS, etc.). In this case, I would select ILS34R, then IF I find the T/D is missing or the route is incomplete, then I go back and select 34R as the arrival. I also usually add a STAR and insert any extra waypoints that are a part of the ILS Approach (from SimPlates ULTRA) to help me hook up with the ILS and GS for 34R.

NOTE: Because I already selected ILS34R as the arrival, the Frequency/Heading for the ILS is already entered into the CDU RAD/NAV page AND the ILS Tuner! So it saves having to enter it manually.

Hmm. Strange. I don't recall that happening to me at all. It might be that the navigation runway database has the threshold 50 metres right of where it really is (at least where it is in FSX). The biggest problem with the newer AIRACS, is that they are based on the real life ones, so things might change hear and there, but a runway 50 metres off, sounds wrong to me.

It might have something to do with the fact that FSX is 10+ years old now and the magnetic variation.  MVAR moves every year (it's about one degree every year), so not sure how the FSX chart people factor that into their nav databases.

I´m away from my Sim PC now, I will return later with the entire flightplan from KLAX-KSEA that I used.

BR,

Thank you very much for your help. I am really amazed with how much effort you put into this.

The route I was flying is this:

RW25R CASTA2.EHF EHF J5 LKV J67 BTG OLM.BTG RW34R

The Frequency 110.3 and CRS 343 now goes automatically in the ILS tuner.
Heading Preference Switch is in Norm.

But next step for me will be to fly the exact same route as you have used.

A few questions.
Do all three A/P´s lit (engage) when you "catch" the GS and Localizer?
In my case only the left one (L) lits as it does during the flight.

Do I have to dial the CRS (343 in this case) in the HDG of the MCP?

Best Regards,
Anders
