Is “Glideslope” different from ILS?

[Yosemitest]

The Glideslope (GS) is PART OF the ILS (Instrument Landing System).

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.

No excuse for ut

“Is “Glideslope” different from ILS?”

Glidelope is one component of an ILS system. It provides the vertical positioning. There is also a horizontal component that guides the plane to the threshold laterally. That component usually comes from a Terminal VOR.
