SECTION 15
RNP CAPABILITY
OVERVIEW
When installed in accordance with AC 20-130A or equivalent, the CMA-9000 FMS is eligible for TGL-10 P-
RNAV and AC 90-100 approvals. The information to support RNP approvals is contained in this section .
This section describes RNP capabilities for the CMA-9000 Flight Management System (FMS) when the civil
navigation configuration is set. This information is intended to be used by operators and regulatory authorities to
facilitate RNP operational approvals. It does not constitute an operational approval by itself. The intent of the
RNP capability section is to address the 95% Total System Error (TSE) accuracy requirement and to declare the
performance monitoring and alerting capability for the applicable navigation modes.
For all navigation modes, the Actual Navigation Performance (ANP) does not include any consideration of the
Flight Technical Error (FTE). The ANP represents the 95% probable radial error of the estimated aircraft
position.
The CMA-9000 FMS monitors the position estimation error and generates an alert when the ANP exceeds the
current RNP.
In GPS navigation mode, the FMS monitors the Horizontal Integrity Limit (HIL) and activates an integrity lamp
and annunciation when the HIL exceeds the RNP value.
FLIGHT TECHNICAL ERROR
In the current implementation, the Flight Technical Error (FTE) is not integrated in the Performance Monitoring
and Alerting. Operational procedures must be developed taking into consideration the (CDI) scaling, auto-pilot
and flight director capabilities to bound the (FTE) as required to support the (TSE) requirements in the RNP
airspace.
Crew procedures should also be developed to address the case when the (FTE) becomes larger and does not
support the RNP procedure.
The FMS drives a course deviation indicator (CDI) with RNP-dependent full-scale deviation (FSD) as described
in the following table.
