RNAV (GPS) LP minima may be used only in which category of aircraft?

RNAV (GPS) LP minima may be used only in which category of aircraft?

• A. Uncertified aircraft
• B. Certified aircraft
• C. Military aircraft only
• D. Experimental aircraft

Answer: (B)

RNAV (GPS) Localizer Performance minima rely on assured navigation performance from certified equipment. The published LP minimums assume the airplane’s navigation system, GPS receiver, flight guidance, and navigation database are properly certified and approved for RNAV LP operations, with the required integrity monitoring and fault-detection in place. If the aircraft isn’t certified or is operated in configurations outside those approvals (such as experimental or military without civilian certification), the navigation performance assumptions behind LP minima aren’t guaranteed, so those minima can’t be used. That’s why certified aircraft are the only ones allowed to fly RNAV (GPS) LP minima.
