This video shows how to determine the rate of descent required to become established on the glide slope on an ILS approach. The climb and descent table is used, but also two methods for figuring the estimated rate of descent to maintain a 3 degree glide path is also shown. These methods are demonstrated with the use of Microsoft Flight Simulator as a visual aid.

This is one of the types of questions on the FAA Instrument Written exam.

Note: In general, an ILS has a glide slope and a RNAV (GPS) approach has a glide path. These two words were used interchangeably on the test question.
