A320/1 Glide Path

Can anyone tell me the precise maximum glide path angle for an A320/1 on an ILS CAT1?
I have the autoland figures but I can't find the above figures anywhere! I think it's about 4+ degrees...

I remember seeing the number3.5somewhere.The Auto pilot seem's to 'fly' the 3.5 quite well(turkey)..Back to the books.

Mmmm........ don't know - can't find it either! However, the ILS GP to R/W 29 @ LTFE (Bodrum/Milas) is 3.9° and we DON'T carry the plates for it. We have to fly the VOR and then circle to land. The only reason I can think of for this is that the Bus cannot (should not) fly a path greater than 3.5°. This is supposition / logic (?) on my part.

We carry plates for and fly the ILS 29 (3.9 degrees) at Bodrum with no problem at all for A320 and A321. I suspect that it's not so much an issue of what G/S angle the autopilot can handle as a limitation based on the angle at which the aircraft can maintain the speed. After all - too steep and it's going to accelerate! It manages 3.9 degrees no problem!

As has already been pointed out, the max G/S angle for autoland is 3.15 degrees, which is a limitation based on flare geometry according to Airbus.

Cheers all
