the maximum estimated time from alignment to the time when the flight will leave Class II Navigation; and

         Note   Class II navigation is an en route operation conducted outside the operational service volumes of ICAO standard NAVAIDS (VOR, NDB, VOR/NDB). Class I operations are those conducted within the operational service volumes of ICAO standard NAVAIDS.

 (iii) the compliance procedures to be used to ensure that all aircraft submitted for approval meet RNP 10 navigational capabilities for the RNP 10 approved time duration; and

 (iv) engineering data to be used to ensure continued in-service RNP 10 capability for the RNP 10 approved time duration.

3.4.2 Non-group aircraft

       3.4.2.1A non-group aircraft is an aircraft for which an operator applies for authorisation on the basis of the characteristics of the unique airframe and the navigation system used rather than because the aircraft is a member of a group.

       3.4.2.2For a non-group aircraft, if airworthiness approval has been based on data collection, the continuing integrity and accuracy of the navigation system must be demonstrated by meeting the data collection requirement for group aircraft.

Note   Data collected by 1 or more operators is acceptable as the basis for authorisation by another operator. An approved data collection procedure is described in AC 91.U-2(0) Appendix 6.

Section 3.5 Determination of aircraft equipment eligibility for CASR 91.5010

3.5.1 Introduction

       3.5.1.1The following groupings are different to the groupings described in section 3.4.

       3.5.1.2These eligibility groups are meant to assist in determining the approval method that may be used to approve specific aircraft and navigation systems.

Note   Doppler systems are not approved for RNP 10 operations.

3.5.2 Aircraft eligibility through prior navigation system certification — Group 1 for CASR 91.5010

       3.5.2.1Group 1 aircraft are those that have obtained formal certification and approval of RNP integration in the aircraft.

       3.5.2.2RNP compliance is documented in the AFM, and may not be limited to RNP 10. The AFM addresses RNP levels that have been demonstrated and any related provisions applicable to its use (eg navaid sensor requirements). Operational authorisation of Group 1 aircraft is based upon the performance stated in the AFM.

       3.5.2.3An airworthiness approval may specifically address RNP 10 performance. The approval includes approval of an appropriate AFM supplement containing the system limitations and referring to the manufacturer's operating procedures applicable to the equipment installed. The AFM supplement may be approved under regulation 138 of the Civil Aviation Regulations 1988 (CAR) with a layout that follows the format for an approved flight manual.

Note   It is proposed to replace CAR 138 with regulations in CASR Part 91.

3.5.3 Aircraft eligibility through prior navigation system certification — Group 2 for CASR 91.5010

       3.5.3.1Group 2 aircraft are those that can equate their certified level
