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 of performance, under previous standards, to the RNP 10 criteria.

       3.5.3.2The standards in this subsection may be used to qualify an aircraft under Group 2.

         3.5.3.3 Transport category aircraft equipped with dual FMSs and other equipment

      3.5.3.3.1 Aircraft having INSs or IRUs, radio navigation positioning updating and electronic map displays that qualify for the /E equipment suffix meet all of the RNP 10 requirements for up to 6.2 hours of flight time.

      3.5.3.3.2 For 3.5.3.3.1, the flight time starts at the later of when the systems are placed in the navigation mode or the last time the systems are updated.

      3.5.3.3.3 If systems are updated during en-route, the effect that the accuracy of the update has on the time limit must be included in the operator's application (see subclause 3.5.6).

Note   The 6.2 hours of flight time is based on an inertial system with a 95% Radial Position Error Rate (circular error rate) of 2.0 NM/hr which is statistically equivalent to individual 95% cross-track and 95% along-track position error rates (orthogonal error rates) of 1.6015 NM/hr each, and 95% cross-track and 95% along-track position error limits of 10 NM each (eg 10 NM/1.6015 NM/hr = 6.2 hours).

      3.5.3.3.4 The aircraft must have the following equipment:

(a) dual FMSs that meet the specifications of:

 (i) FAA AC 25-15 Approval of Flight Management Systems in Transport Category Airplanes,              FAA AC 20-129 Airworthiness Approval of Vertical Navigation (VNAV) Systems for use in the US National Airspace System (NAS) and Alaska and FAA AC 20-130A Airworthiness Approval of Navigation or Flight Management Systems Integrating Multiple Navigation Sensors; or

 (ii) equivalent criteria as approved by CASA;

(b) a flight director and autopilot control system capable of following the lateral and vertical FMS flight path;

(c) at least dual inertial reference units (IRUs);

(d) a database, containing the waypoints and speed and altitude constraints for the route and procedure to be flown, that is automatically loaded into the FMS flight plan;

(e) an electronic map.

Note   These requirements are set out in the US Aeronautical Information Manual (AIM), Table 5-1-2, Aircraft Equipment Suffixes - Area Navigation Systems. Under the US system, these aircraft qualify for the /E suffix.

         3.5.3.4 Aircraft equipped with INSs or IRUs that have been approved under CFR Part 121

      3.5.3.4.1 INSs or IRUs approved under Appendix G of FAR Part 121 meet RNP 10 requirements for up to 6.2 hours of flight time.

      3.5.3.4.2 For 3.5.3.4.1, the flight time starts at the
