6 ISSUE RNP (Required Navigation Performance) data included in the LP and LPV approaches that are attached to the end of this service alert cause the scale factor of the CDI (Course Deviation Indicator) to be incorrect. The incorrect scale factor affects the displayed course error on the CDI. PILOT ACTION Until navigation database cycle 1501 (or later) is loaded, do not fly LP or LPV approaches that annunciate RNP near the center of the HSI (see Figure 2) when the active waypoint is the final approach fix (FAF) or the aircraft is on final approach inside the FAF. A list of these approaches is attached to the end of this service alert. Figure 2 - HSI RESOLUTION This issue will be resolved in navigation database cycle 1501 (and later).
