What is required for an alternate airport when using GPS for navigation and instrument approaches?

• A. An approved operational instrument approach procedure other than GPS
• B. A direct approach using only GPS
• C. A VFR approach procedure
• D. No specific approach required

Answer: (A)

When utilizing GPS for navigation and instrument approaches, having an approved operational instrument approach procedure other than GPS is essential for an alternate airport. This requirement is particularly important because it ensures that there is a reliable and established means of landing at the alternate airport if weather conditions or other factors necessitate diverting there. Using a non-GPS approach provides redundancy and mitigates the risk associated with potential GPS signal loss, ensuring that pilots have access to a reliable approach just in case the GPS system encounters issues. This requirement is in line with aviation safety protocols that emphasize having multiple navigational aids and procedures available for landings to enhance operational safety. Other options, such as solely relying on a direct GPS approach, opting for a VFR approach procedure, or having no specific approach required, do not satisfy the safety standards established for alternate airport planning.
