autoland

[Captain_BH]

hi guys

can someone explain this:

Airbus fcoms says that the glide slope by itself might be sometimes inaccurate ... or for example capturing false ILS

I have read some articles here that Autoland is always safe and accurate

1. would a false ILS or GS affect the operation of AUTOLAND ??
2. Do FDs follow the ILS beams or the installed data in the Boxes ??

Thanks
