What should a pilot do upon receiving a RAIM error while flying the RNAV(GPS) RWY 30 approach to LBF?

When a pilot receives a RAIM (Receiver Autonomous Integrity Monitoring) error while conducting an RNAV (GPS) approach, it indicates that the satellite signals do not meet the necessary integrity standards for navigation. In this situation, the pilot must prioritize safety while ensuring compliance with the approach procedures.

Choosing to continue to the missed approach point while climbing to 4,900 feet is the correct response because it aligns with the protocol for dealing with RAIM errors and allows the pilot to safely complete the approach. This option ensures that the aircraft remains within the terminal airspace limits and prevents any abrupt altitude changes that could lead to an unsafe situation. By climbing to the appropriate altitude while proceeding towards the missed approach point, the pilot remains prepared to execute the missed approach procedure if necessary, allowing for a transition to a safe altitude and course of action.

This response acknowledges the integrity loss while allowing the pilot to make informed decisions based on the prevailing conditions and procedures. The missed approach point is designed for situations where an aircraft cannot land, and completing the approach to that point ensures adherence to the established flight path.
