A recent territorial spat between the countries Malaysia and Singapore over an ILS implementation made me curious. I'm interested in finding out about ILS and how an implementation of one would affect the surrounding urban restrictions.
In that specific example, one country is saying that the ILS implementation would stifle its economic growth by restricting building height if the flight path went according to the yellow path showed on this picture
The question is, can the ILS still work if the flight path is altered to, say, an angled landing going through the water (along the thin white line) from North to South? Is it possible for a plane to turn and land into the airport (and bypass the land, hence removing building height limits) while still benefiting from the ILS in this case?
Note: The airport is 2km away from the other side of the shore (which is a separate country)
