Pre-Flight
I'm planning on flying into Jackson Hole (KJAC), and after looking over the approaches I noticed something odd. ILS or LOC RWY 19 has two plates, Y and Z. On Y the minimums are higher, and there's a note saying fly visual at DH from 1.8 miles out...kind of like a non precision MDA. My question is, why do these two approaches exist? And when might you ever choose to fly Y instead of Z with lower minimums?
