[Obvious replies inserted] And that is? How would you identify it?


Since I'm on the GS when my GS receiver fails my distance from the MAP is
directly proportional to my altitude above DH. A 3 degree GS drops 318' in
each nautical mile. If I'm about 1000' above DH I'm about 3 miles from the
MAP. Simple.
