Has anyone tried (successfully) to tie Bill McClelland's TFR (it's part of his Pave Tack package) into the B-52 autopilot?  I realize the TFR is designed to work with an autopilot that accepts a target altitude, which the B-52 does not, but I was able to integrate TFR with an A-10 from another supplier that functions similarly to the B-52.  I've tried a lot of procedures with the B-52 but the moment I engage the altitude hold the aircraft goes nuts, either climbing or descending steeply. Thanks in advance for anyone's experience.
