If you fly the ils approach correctly, the plane will glide down the glide slope like a stripper on a greasy pole.

Not true. An autopilot should never oscillate in pitch for more than a few seconds. Power/airspeed/config all irrelevant. 

I'm sorry but there are 20 different ways to achieve any descent profile in an airplane like the 930. To say "power/airspeed/config all irrelevant" is just nonsense.

If I say so? Some of you guys are hilarious lmao

None of them have anything to do with a pitch-oscillating autopilot. You can descend any way you like, an autopilot does not 'bob' in pitch.

Honestly...why can't people who don't wan't to help or contribute to the OP just stay away? Don't you have better things to do?

I'm confused: what is this video posted on the previous page supposed to demonstrate?

Seems to happen when tracking the glide slope -- typically when inside the FAF with gear down, full flaps, and 85 knots -- so the standard approach configuration.

Al

Yes I have noticed this too, the TBM also does not always follow the glide slope accurately.

That: "this plane really likes to oscillate.....up and down with the pitch...when on ILS down and low" (18:05 in video) and he's therefore handflying from 500 ft. down. It's a great find and shows that real world autopilots have their flaws too. While I think there's defintely room for improvement with the MSFS autopilot I never had the OP problems with pitch oscillation on approach in the TBM. I had pitch oscillation during one whole flight once, and that vanished after deleting a mod I was using at that time. Power/speed/config matter a lot, be it in sim or in the real airplane. Then there's wind and turbulence, control sensitivity and -quality (spikes?) to be considered. However, I noticed that the AP in the TBM tends to sway left and right by up to 5 degrees enroute before "settling" on a new track of the flightplan, so maybe the programming in general has it's part in the problem some are seeing and others are not.

Mmmmm, maybe the guy is just not a very good pilot. He admits himself that "he's too fast on the approach".

I did, I posted a video showing that I didn't have the problem the op mentioned

I believe he's talking about that individual Plane...not the type in general. But i could be mistaken though....

Aside from the fact that repeating nonsense doesn't make it true, tell that to the most famous TBM pilot in the world (@18:07): "This plane really likes to oscillate on ILS's down low, up and down with the pitch."
