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 permitted
• C. RNAV (GPS) LP minima not authorized; FMS Speed Module prohibited
• D. RNAV (GPS) LP minima authorized in certified aircraft; FMS Speed Module optional

Answer: (A)

RNAV (GPS) LP minima require the aircraft to have the approved navigation performance and certification for those specific minima. That means only certified aircraft may publish and fly LP minima because their avionics, databases, and procedures have been evaluated to meet the required accuracy and reliability. Uncertified aircraft don’t have that authorization, so LP minima aren’t allowed there. In an engine-failure scenario, the approach speed and maneuvering plan depend on predictable performance and constrained speed schedules that the crew must manage with approved procedures. The FMS Speed Module is not permitted in engine failure because relying on that automated speed control could conflict with the required speed constraints and reduced-thrust performance, potentially compromising safety margins. So the true combination is that RNAV (GPS) LP minima are authorized in certified aircraft, and the FMS Speed Module is prohibited in engine failure.
