Out of sight planes during final approach Does it ever happen that planes descending on a descent path (glide slope) block each other so that one (or more) plane is not visible from the tower (at the airport) or localizer? I want to know if that can cause technical issues. For example, how does a plane track a localizer if it's being blocked by the plane(s) in the front?
The 2nd plane's pilot should notice that he is not receiving the localizer on his instruments and break off the approach.
