I set-up the course, ILS frequeny and on the approach, I engaged the approach button. At this point, the plane turns as if to approach the runway, but falls drastically out of the sky.  I don't have any problem with other planes I fly, using this procedure...please, what am I doing wrong with the C-130?

Thanks Yannay for the info.

Well, I'm not a pro at this stuff...learning. I do fly serveral Captain Sim aircraft, the 727, 757, others and have no problem with the ILS approach. I set-up the Flight Plan for the C-130 the same as these aircraft...select IFR for the type of flight.  The C-130 radio is set to the ILS frequency of the airport.  I select the NAV ILS mode and prior to the approach, I select the approach or glide slope button. At this point the  C-130 goes astray. On the other aircraFT...smooth, straight on  to the runway.

I'll check out the KB-417

OK Yannay...let me know what you come up with. I have always set up the flight plan in FS9 using an IFR plan and following the ATC for directions. They always instruct to come in @1500 feet and I haven't had any problem landing the planes in my files, except for this C-130. My brother was having the same problem and he said he finally got it to work by setting up a GPS flight plan.  He said he flew the plane in the GPS mode and when he started making the final approach, he switch to the NAV/LIS mode and click the glide slope button...perfect landing for him. I tried this and couldn't get it to work either. I'll get back witih him and let him walk me through and see what happens. In the mean time keep me posted Yannay...thinks.  

OK  Yannay...I'll give it a try. Maybe this will give me a hint as to what I'm doing wrong... many thanks for your diligent help. Will keep you posted on how things work out.

congratulation! no problem for helping you up.
