Agenda Item 7: ANSP Monitoring
POST IMPLEMENTATION MONITORING DEVELOPMENT OF
RCP AND ADS LATENCY
(Presented by Airways New Zealand)
SUMMARY
This paper provides a further update on RCP monitoring by Airways New Zealand. The
paper provides information on current measured performance together with information on
some of the analysis that has been undertaken when identifying performance issues. We
intend to use this development work and any feedback received during the process to
generate the draft GOLD Appendix D covering FANS1/A post implementation monitoring.
1. INTRODUCTION
1.1 Airways New Zealand has been developing FANS1/A monitoring to the Oceanic SPR
standard since October 2007. We previously reported on this development at
ISPACG22 FIT/15 in WP-04. WP-04 discussed the methodology used to extract the
Actual Communications Performance (ACP) and Actual Communications Technical
Performance (ACTP) for CPDLC and the latency for ADS reports and provided
illustrations of the type of performance data that was extracted.
1.2 This working paper discusses our current thoughts regarding post implementation
monitoring and has been prepared to generate discussion on this topic as we plan to
use the views expressed in this paper to further develop the draft GOLD Appendix D
which will provide global guidelines for FANS1/A post implementation monitoring.
2. DISCUSSION
2.1 Our experience in the last 12 months has continually emphasized the importance of
monitoring by individual ANSP of the FANS1/A performance in their airspace.
Performance differences have been identified between the same airline fleets in
different airspaces. Two recent examples of this are the lower than expected CPDLC
performance from the UAE A345 and B773 fleets on westbound Tasman routes, and
the performance of the A388 fleets which are showing lower than expected
performance in NZZO when compared with other Airbus fleets operating in our
airspace. However, with the A388 Air Services Australia are reporting normal

performance in their airspace. The amount of analysis time needed to extract these
performance differences is currently quite extensive as a lot of manual analysis is
necessary. The development of analysis tools that will automate the majority of this
work is seen as an important prerequisite for the type of monitoring that will be
needed.
2.2 We consider most FANS1/A problem reports derived from RCP monitoring will be
generated by data analysis at individual ANSP. It is the ANSP that has immediate
access to reported issues as they occur, and probably more importantly has the local
knowledge and resources needed to review the data for any degraded performance
noticed in their airspace. We feel that a regional CRA may struggle to do the type of
analysis needed both from the availability of resources required to do the analysis and
also a lack of local knowledge. The regional CRA would in our view be better suited
to aggregating actual reported RCP performance data from individual ANSP to derive
regional performance data figures and issues that may be viewed by other regions. If
required global aggregation of this regional data could be easily achieved.
2.3 We propose that each ANSP will provide the CRA with monthly performance data for
