FAA Instrument Rating Written Practice Exam - Prep & Study Guide

The Minimum Safe Altitude (MSA) during a missed approach from an RNAV (GPS) approach is designed to ensure that aircraft maintain a safe clearance above any obstacles in the area while maneuvering. The MSA is typically found on the approach plate and is calculated based on the highest terrain or obstacle within a specific distance from the airport and the approach procedure being used.

In this case, when the MSA is stated as 5,800 feet MSL, it reflects the established altitude that provides the necessary safety margin. It is determined by considering the maximum elevation of terrain and obstacles that could potentially pose a risk during a missed approach. Maintaining this altitude ensures that pilots are operating safely above all known obstacles and can execute a missed approach without endangering themselves or their aircraft.

The other options provided do not reflect the correct altitude as found on the associated approach procedure, as they might be below the MSA or not align with the safety standards set for the specific missed approach procedure. Therefore, selecting 5,800 feet MSL indicates an understanding of the importance of adhering to established MSA guidelines for safe operations during a missed approach phase.
