What does the number in degrees indicate on an approach chart?

On the following ILS chart, there is a number 301°. Is the number 301° indicating a track angle, heading or something else?

• Ask yourself what makes sense. What could be published and always be useful to the pilot in all situations and would maintain the same relationship with the fixed points on the plate.

• @Jim that is not a helpful comment. What might seem obvious to you could seem very perplexing to someone starting out. APP CRS only means "Approach Course" for those of us who are used to the jargon. And showing an approach angle on the bottom right glidepath has always been a confusing representation. Snappish responses might feel temporarily feel good, but they don't celebrate the learning and documentation process, which is what SE sites are about. Mar 7 at 15:08
• @KennSebesta - That wasn’t a snappish comment. I’m sorry you took it that way. It was a comment in the vein of the Socratic method intended to stimulate critical thinking.
