During the ILS RWY 13 procedure at DSM, what is the altitude minimum if the glide slope fails?

In an Instrument Landing System (ILS) approach, if the glide slope fails, pilots must refer to the published decision altitude or minimum altitude required for a successful approach without the glide slope guidance. During the ILS RWY 13 procedure at Des Moines International Airport (DSM), the minimum altitude in the event of a glide slope failure is indeed 1,380 feet.

This altitude is determined as part of the approach plate, which outlines specific minimums for pilots to follow for safety. The decision to use this altitude ensures that the aircraft remains clear of any obstructions while still allowing for safe landing operations. Adhering to the minimum altitude is crucial during approach and landing phases to maintain safety standards, especially in the absence of glide slope assistance.
