ILS, LOV, LOC BC, LDA, and SDF approaches are _____ when utilizing the FMS.

When utilizing the FMS (Flight Management System) in a King Air 350, ILS, LOV, LOC BC, LDA, and SDF approaches are considered prohibited from the FAF (Final Approach Fix) to the MAP (Missed Approach Point). This prohibition is essential because these types of approaches rely on specific navigation and guidance systems that may not be compatible with the FMS in certain operational contexts. The use of FMS for these approaches can lead to navigation errors or deviations from the intended flight path, as the FMS is generally optimized for the more precise and standard RNAV (Area Navigation) and GPS approaches that allow for greater automation and accuracy. Understanding these limitations is critical for ensuring safety and compliance with aviation regulations.

In essence, staying within the guidelines surrounding the usage of various approach types ensures that pilots maintain the highest levels of situational awareness and adhere to best practices during instrument approaches.
