Plain English Meaning

This is the name of one particular GPS-based approach chart for Runway 15R. The letter 'Y' is just a label so pilots and controllers can tell it apart from another GPS approach to the same runway, like a 'Z' version. Each version has slightly different ways of getting started or different minimum altitudes you can descend to.

Full Definition

The title of a specific published instrument approach procedure that uses Area Navigation based on GPS to guide an aircraft to Runway 15R. The letter 'Y' is an alphabetical suffix used to distinguish this chart from other RNAV (GPS) approaches to the same runway (such as a 'Z' version), which typically differ in their initial segments, transitions, or supported approach minima.

Context Anchor

Seen at the top of an instrument approach chart and when selecting or briefing the approach before flying it.
