and

(d) tell ATC of any deterioration or failure of the navigation equipment below the navigation performance requirements or of any deviations required for a contingency procedure.

3.10.5 Flight crew knowledge

      3.10.5.1 An AOC holder must ensure that flight crew members have been trained and have appropriate knowledge of:

(a) this MOS; and

(b) the limits of their RNP 10 navigation capabilities; and

(c) the effects of updating navigation systems; and

(d) RNP 10 contingency procedures.

      3.10.5.2 A private operator must show CASA that the operator's pilots have appropriate knowledge of RNP 10 operations.

Chapter 4 Required Navigation Performance 4 (RNP 4)

Section 4.1 Overview

4.1.1 Background

       4.1.1.1ICAO Annex 6 — Operation of Aircraft requires that an operator must obtain RNP operational authorisation from the State of the operator (for international commercial air transport operations) or the State of registry (for international general aviation operations) before conducting flights in defined portions of airspace or on routes where RNP types have been prescribed.

4.1.2 Applicability

       4.1.2.1Under CASR 91.005, the standards in this chapter apply to Australian operators of Australian or foreign registered civil aircraft, and flight crew, seeking approval to undertake RNP 4 operations.

       4.1.2.2Australian registered aircraft, when operating outside Australian territorial airspace (i.e. beyond the 12 NM territorial limit), must comply with:

(a) when over the high seas — ICAO Annex 2; or

(b) when operating within another State's airspace — the applicable regulations of that State.

4.1.3 Approval to undertake RNP 4 operations

       4.2.3.1Under CASR Division 91.U.4, CASA may grant an approval in the form of an RNP 4 operational authorisation to an operator to undertake RNP 4 operations.

Section 4.2 Operational authorisation process

4.2.1 General

       4.2.1.1Under CASR 91.5155 (3), 91.5160 and 91.5170, the steps that must be completed before an RNP 4 operational authorisation is issued to an operator are:

(a) CASA reviews the existing certification of the aircraft navigation equipment and makes a determination that it is eligible for RNP 4 operational authorisation;

(b) the operator identifies the flight crew training and operating procedures for the navigation systems to be used for RNP 4 operations;

(c) CASA evaluates the operator's database use, flight crew training and operating procedures.

4.2.2 Limitations

       4.2.2.1For CASR 91.5010, authorisation for RNP 4 operations is only given for an aircraft that has received airworthiness certification indicating that the installed navigation systems meet the performance requirements for RNP 4.

       4.2.2.2The authorisation may have been issued at the time of manufacture or if the aircraft has been retrofitted in order to meet the requirements for RNP 4, by the granting of an appropriate supplemental type certificate.

       4.2.2.3For CASR 91.5010, authorisation may be given only for aircraft for which the certification of RNP 4 navigation capability
