OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
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 tables.
When FMS configured with RNP full scale deviation = YES.
Current RNP (nm)
HSI FSD [nm]
RNP lower than 1.0 0.3
RNP between 1.0 and 1.99
1.0
RNP between 2.0 and 3.99
2.0
RNP greater than 4.0
4.0
