I have always been wondering so I know when to extend my gear.

Markers:

  1. The Outer Marker at approximately 5nm helps the a/c adjust its course and height.
  2. The Middle Marker is located at approximately 3500 feet and used similarly.
  3. The Inner Maker at 1000 feet is used only for Category II operations.
