OK... I'm curious as to how that "flexibility" is achieved?
MLS beams are not distorted to same extent, so protected area(s) are much smaller. So spacing on approach, even in LVPs can be less (5NM v 8NM?), also To to Ldg spacing (I believe ILS needs dpearintg aircraft beyond LOC aerial as arriving is at 2NM, MLS can be dep aircraft "airborne" with approaching at 1NM).
You can also do curved approaches etc.
Of course, seeing those theoretical benefits, and getting the airfeld / ATC system to adopt the reduced spacing in practice, is another matter. As, errrr, being discussed between LHR and one of the larger operators there
