ILS has two parts: Glideope and Localizer. Most ILS approaches are set up to use with glide slope out of service. There are just different minimums required to see the field.
Unless there was a serious malfunction of the aircraft systems, this is worse than pilot error. It was gross incompetence.
At UAL we are required to have stabilized approach criteria by 1000 feet: gear down flaps down on glide path, engines spooled up. Without that a missed approach is REQUIRED.
The 777 can calculate and display its own calculated glide path so glides lope out is not a big deal. There had to be all sorts of oral warnings going off prior to landing. EGPWS, GPWS radar altimeter call outs.
