That guidance may be, in some cases, the radar-enhanced eyes of air traffic controllers saving a pilot from a tall tower or CFIT - controlled flight into terrain. The help may be the guidance of an instrument landing system approach - or a GPS-based approach using a lateral precision with vertical guidance procedure. It may even be the eye of a technology increasingly helping pilots avoid tall towers, terrain, traffic or even wildlife - particularly at night. The technology: enhanced vision systems. The sensor of an EVS can deliver vision where the human eye fails - and improve the view where the eyeball needs a little help.
