Completely understand the bit about 2 missed approaches, but the rest is gibberish! I believe that the ILS is presently out of service on one of the R/W's at GVA and the substitute approach is a Non-Precision approach (no Glide path information) which brings the A/C in at alot steeper angle (approx 4 degrees); this can sometimes lead to the a/c not making the stable approach criteria resulting in a Go-Around; of course there are also many other reasons including the R/W still being occupied etc.....
