Glide slope loss

[Guest kevchris]

The recent service update seems to have corrected the rudder issue when on final approach. Now the aircraft can be enjoyed by a "novice pilot" like I am. However, I am still losing the glide slope on an ILS approach. Everything seems fine, with the aircraft descending on the gs - then all of a sudden the nose pitches upwards, and I am forced to disable the AP and land manually.What am I doing wrong here??Thank you for your help.

Kevin,That sounds like Alpha-Floor(stall protection) kicking in. At what speed were you at, at what altitude, what were your flaps at, and were your gear deployed?

Hi.When I experience this, I'm to fast. However, the MCP speed becomes active to late for me to adjust it; I'm still on FMC speed/alt restrictions upon first wpt. in ILS. (184/2000) So when I press "APP", it take to long a time before I can adjust speed on the MCP (it remains black for some time), and then it is to late for the bird to slow down to my set speed of 133. Dilemma!

One way to work around this is to manage your speed on approach is to revert to V/S and SPD for the final segments. If we had speed intervention you could open up the speed window in the MCP and enter a speed while still in VNAV. But as you can see on the MCP, there's a metal plate covering the hole where the speed intervention button should have been. As I understand it not many operators have the speed intervention option installed. I know SAS doesn'tHope it helps,

Hi.I have experienced this, like Anders, only if I am too fast on approach, and with that speed, angle, and flaps, the ac can
