         Section 4.3 Aircraft eligibility groups, technical requirements and explanation of terms for CASR 91.5010

4.3.1 Aircraft eligibility groups

       4.3.1.1Group 1 aircraft have the following characteristics:

(a) the aircraft have obtained formal certification and approval of RNP integration in the aircraft;

(b) RNP compliance is documented in the flight manual and may not be limited to a single RNP type;

(b) the flight manual addresses the RNP levels that have been demonstrated and any related provisions applicable to their use (eg navaid sensor requirements);

(c) operational approval is based on the performance stated in the flight manual;

(d) a supplementary type certificate may be issued to cover retrofitting of equipment, such as GNSS receivers, to enable the aircraft to meet RNP 4 requirements in oceanic and remote area airspace.

       4.3.1.2Group 2 aircraft are those that can equate their certified level of performance, given under previous standards, to RNP 4 criteria.

       4.3.1.3Group 2 aircraft include aircraft fitted with:

(a) Global Navigation Satellite Systems (GNSS) as an approved long-range navigation system for oceanic and remote airspace operations that meet the technical requirements mentioned in clause 4.3.2, if:

 (i) the AFM states that the dual GNSS equipment is approved under FAA Technical Standard Orders (TSO) C129a or C146a, or JAA Joint Technical Standard Orders (JTSO) C129a or C146a; and

 (ii) there is an approved dispatch fault detection and exclusion (FDE) availability prediction program; and

 (iii) the maximum allowable time for which FDE capability is projected to be unavailable is 25 minutes; and

 (iv) if predictions indicate that the maximum allowable FDE outage will be exceeded, a rescheduling of the operation is required for a time when FDE is available; or

(b) multi sensor systems integrating GNSS with integrity provided by RAIM, and multi-sensor systems integrating GNSS with RAIM and FDE, that are approved under FAA AC 20-130A or other equivalent documents; or

(c) multi sensor systems integrating GNSS:

 (i) with integrity provided by Aircraft Autonomous Integrity Monitoring (AAIM) that uses the redundancy of position estimates from multiple sensors, including GNSS, to provide integrity performance that is at least equivalent to RAIM; and

 (ii) if certified in accordance with TSO C-115b, JTSO C-115b or other equivalent documents (eg the use of an inertial navigation system (INS) or other navigation sensors as an integrity check on GNSS data when RAIM is unavailable but GNSS positioning information continues to be valid; and

 (iii) for which the INS or inertial reference unit (IRU) is approved in accordance with FAA Part 21 Appendix G).

    4.3.2 Technical requirements

       4.3.2.1Navigation accuracy has the following characteristics:

(a) it is defined relative to a geodesic path along
