What is an instrument approach?
An instrument approach is the process of beginning a landing without being able to visually see the runway due to weather conditions such fog, smog, haze, clouds, etc. In order to land, the pilot must rely solely on the instruments inside the plane to safely guide the plane down near the ground. There are several different systems available to assist pilots in landing the plane using their instruments an airline pilot must be highly proficient with all of them.
