Hi everbody. I've got an annoying problem. I created a flight from Heathrow to Brussels National an started to fly. As I got near to the destination, I turned on NAV HOLD to get me aligned with the runway I was cleared for (25R). I tuned into the ILS and my plane started turning. It stopped and I could see the runway. But the plae couldn't properly align itself; it just kept turning bent then bent again, it tried over and over again but it just couln't do it! I'm using the POSKY B744. Help please. Thx

Your intercept angle for the Localizer may have been too extreme as well. When this happens, the a/c will "chase" the localizer.
