What is the side view of an approach plate called?

The side view of an approach plate is referred to as the profile view. This view provides critical vertical information about the approach procedure, illustrating altitude requirements, waypoints, and glide slope information along the path of descent. It allows pilots to visualize the changes in elevation and important vertical references, which are essential for safe navigation during the approach to an airport.

Understanding the profile view is crucial for pilots as it helps in planning and executing descents and alignments with the runway. The information depicted in the profile view complements the plan view, which shows a top-down layout of the approach procedure, emphasizing the importance of both perspectives in aviation navigation.
