Extract of AC 90-101(Appendix 6, 12/15/2005)
1. The operator must have an RNP monitoring program to ensure continued compliance with the guidance of this AC and to identify any negative trends in performance. At a minimum, this program must address the following information. During the interim approval, the operator must submit the following information every 30 days to the CHDO or FSDO granting their authorization. There-after, the operator must continue to collect and periodically review this data to identify potential safety concerns, and maintain summaries of this data. 
a.
 Total number of RNP SAAAR procedures conducted. 

b.
 Number of satisfactory approaches by aircraft/system (Satisfactory if completed as  planned without any navigation or guidance system anomalies). 

c.
 Reasons for unsatisfactory approaches, such as:  1) UNABLE REQ NAV PERF, NAV ACCUR DOWNGRAD, or other RNP messages during approaches.  2) Excessive lateral or vertical deviation.  3) TAWS warning. 4) Autopilot system disconnects.  5) Nav data errors. 6) Pilot report of any anomaly. 

d.
 Crew comments.

7.2.7 MAINTENANCE
There is no specific or scheduled maintenance tasks for RNP AR operations. 
The maintenance organization should be aware of the minimum equipment required to fly the
intended RNP AR operations. 

7. RNP AR Operations and Training

-49 -
7.3  FLIGHT CREW AND DISPATCHER TRAINING
The airline needs to define a flight crew training that is adequate to the type of operations being envisaged. The training can be generic if all operations are equivalent, but may need to be specific for operations that are significantly different considering the type of flight path, DA location or environment.
The flight crew training to fly RNP AR procedures should include a ground school segment and a Full Flight Simulator segment.
The ground school segment should include a briefing (or briefing note) on:
.  
The concept of RNP AR operations,

.  
The aircraft systems to fly RNP AR procedures,

.  
Flight crew procedures in addition to the FCOM SOP for RNAV procedures,

.  
The specificities of each RNP AR procedure,

.  
RNP AR procedures charting. 

The Full Flight Simulator segment should highlight:
.  
The use of FINAL APP mode,

.  
The flight crew procedures specific to RNP AR operations in general or specific to particular RNP AR procedures,
