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. :)
