Which combination statement is true?

• A. RNAV (GPS) LP minima authorized in certified aircraft only; FMS Speed Module prohibited in engine failure
• B. RNAV (GPS) LP minima authorized in uncertified aircraft; FMS Speed Module is required in engine failure
• C. RNAV (GPS) LP minima not authorized; FMS Speed Module may be used during engine failure
• D. RNAV (GPS) LP minima authorized in certified aircraft only; FMS Speed Module can be used in engine failure with ATC approval

Answer: (A)

RNAV (GPS) LP minima depend on having an approved and certified navigation system that guarantees the required lateral accuracy. Only aircraft that are certified for RNAV (GPS) LP procedures meet those standards, so LP minima are authorized only in certified aircraft. Uncertified aircraft lack the necessary certification and navigation integrity, so they cannot use LP minima. For engine failures, the speed management in the cockpit must follow established performance and procedure rules. The FMS Speed Module is not permitted to be used during an engine failure because relying on it could compromise safety when thrust is asymmetric and speeds must be controlled manually according to the applicable procedures. Putting those together, the combination that aligns with these rules is that RNAV (GPS) LP minima are authorized in certified aircraft only, and the FMS Speed Module is prohibited in engine failure.
