Not according to the Link provided by ACMS above. GLS does not necessarily need a database coding as the approach geometry is transmitted on the selected channel and decoded and compared against the corrected GPS position in space in the MMR and the result shown as normal ILS position. FLS seems to use a FMS database coded procedure to construct an ILS lookalike lateral and vertical path. In that it is very much like IAN which uses a FMC database coded NPA for the same thing.

And of course GLS approaches are "just" normal precision approaches, albeit currently only approved to CAT I although they have been tested to CAT IIIb with very good results. Accordingly, autoland is possible from that. No idea if FLS allows autoland, boeing IAN, at least in the 737, on NPAs levels off at 100ft and an autocallout "AUTOPILOT" reminds one to disconnect the autopilot.
