Rob or Trevor, when I couple up on the ILS, everything goes well until about 500 feet above touch down, and the pitch seems to go a bit erratic, the aircraft will go high with no immediate indication for a pitch down from the FD, then there will be a large pitch down command, followed by a rapic descent below the glide slope, followed by another "fugoid" oscillation. Do I need to change settings for the FD or the "altitude"?

Regards,
