I have tried following one of the YouTube tutorials on setting up & flying an ILS landing in the MD-82, without success.

When I am 'in the feathers' & under 3,000', I can't get VOR LOC to capture, or G/S TRK to appear, when I hit the ILS button.

(HDG HLD & ALT HLD remain steady in the status box & I just fly down the length of the runway, without losing the approach height)

I have copied the tutorial settings as regards NAV & Course & am scratching my head over what actions I could be missing out.

Are there any 'step by step' written, or video, MD-82 ILS landing guides anywhere?

Further to the original post, I have figured out what the issue was.

I was coming in too high & flying above the glidepath.

I was using EGSS, which has an altitude of 348' & I didn't allow for that.

In the end i needed to arrive into the feathers  at around 2,100' for everything to lock on.

Now I need to work on slowing the MD-82 down, it comes in quite quickly.

I believe if you hit that FAF at published altitude or slightly below you should have no problem capturing GS each and every approach.

Quoting heights without a distance is meaningless.  For a 3 degree glideslope you can use the "3x" approximation - 3000 feet 10 miles out.  If you were at 3000 ft (above the runway, but that's usually a minor correction) less than 10 miles out you were definitely above the glideslope!  Ideally you should be a bit below that altitude, in level flight or a slow descent, so as to capture the glideslope from below.  Capturing from above means a rapid descent which could be uncomfortable and risky.  Some older autopilots - not sure about the MD-80, even less sure about the LSH model - would not capture the glideslope from above for this reason.  Modern electronics are more reliable, but it is still a usually undesirable practice.

A good thing is not to coming in over the GS pointer, i allways look that the GS pointer comes from the upper side down to the capture point so i allways get a capture..

Some planes does not capure the other way but i didn`t tried that with the Maddog x

cheers 😉

It helps that the Maddog has pretty high flap limit speeds, so if you seem to be going too fast, chuck everything out (keeping an eye on the limits,of course) and watch her plummet.
