What is the minimum altitude for glide slope interception during the ILS RWY 13 procedure at DSM?

The minimum altitude for glide slope interception during an Instrument Landing System (ILS) approach is crucial for ensuring that the aircraft is at a safe altitude while capturing the glide slope. The correct answer indicates that the minimum altitude for glide slope interception during the ILS RWY 13 procedure at DSM is 2,600 feet MSL (Mean Sea Level).

This altitude is established to provide sufficient terrain clearance for the aircraft as it approaches the runway, taking into account the specific terrain and obstacles in the area surrounding the airport. The glide slope provides a vertical guidance path to the runway, and intercepting it at the prescribed altitude ensures a safe, stable descent towards landing.

It’s essential for pilots to adhere to published procedures such as these to maintain safety during the approach phase, and the altitude specified aligns with federal aviation regulations and the procedures set forth by the approach plates for that specific runway and airport.
