Which statement best describes RNAV (GPS) LP minima authorization?

• A. They are authorized for all aircraft
• B. They are authorized in certified aircraft only
• C. They require the use of the FMS Speed Module
• D. They are prohibited in all operations

Answer: (B)

RNAV (GPS) LP minima rely on the aircraft’s navigation system meeting specific certification standards. Localizer Performance (LP) is a GPS-based lateral guidance capability that can only be used if the aircraft’s equipment is certified for LP operations and the operator has the appropriate approvals and database access. Because the authorization depends on having certified RNAV/GPS equipment and the required operational credentials, these minima are not available to all aircraft. The statement that best describes this is that LP minima are authorized in certified aircraft only. The other ideas aren’t accurate: not every aircraft has LP authorization, there isn’t a universal requirement for a particular FMS Speed Module to use LP minima, and LP minima aren’t prohibited in all operations.
