This tutorial covers the basics of the ILS (Instrument Landing System) and IMO, the three (3) things virtual pilots need to make any ILS approach to any runway with a ILS system.
I believe my "Three Numbers System" simplifies the procedure, but is enough to allow beginners and veterans to perform and successfully fly a ILS approach anywhere in the (virtual) world the ILS exists.
Aircraft: Default 737-800

NOTE TO AVIATORS: If you are a real world pilot who would like to comment on my tutorials, you are more than welcome to.
However, keep in mind FSX is a simplified video game intended for a mass audience. Therefore, not every single thing is going to be 100% accurate to your real world experience.
