When I fly a BC ILS the localizer is right down the middle but the glideslope is NOT as I am using autopilot.  

Autopilot practically takes me all the way to the threshold of the selected rwy keeping the localizer and the glideslope centered, but not when I fly the backcourse ILS, why not  ???

sir-knight, flying the back course will keep you on the line, but there is no glideslope on it - you have to handle the descent manually.

No doubt about it . . . I always get really good advice / answers everytime I post a question to you folks, thanks.  

If you keep N1 at about 55%, with gear and flaps down, and trim the aeroplane properly, the rate of descent should be about 500 feet/minute, which is what you want.  Too steep, add power, too shallow, reduce it.

Not in jets-only in props is this the proper method for maintaining glideslope.  In jets, pitch for altitude, power for airpseed.

"sticking the nose in the air if you are going too slow?"

Did my flght instructor say it better? with: "Get that nose down you hog lubricator!"

("hog lubricator" is a euphemism for excrement  ::)

One can't beat those old military pilots when it comes to flght training. Yes, that was the last time I came in suck-holing up to the numbers!

P.S. . . . did anyone say there was no GP on the BC?
Or, put another way: What part of No GS on the BC don't you understand?

...mmm...POWER for altitude and PITCH for speed is what I was encouraged to think.......

Like I said earlier, this is only for props.  While naturally a bit of power is to be added when you increase attitude, pitch for altitude is still the correct procedure in jets.  And if you have A/T on, it does it automatically anyways.
