routes. These checks are in addition to any checks performed by the Aeronautical Information Services, unapproved navigation database suppliers or navigation equipment manufacturers.

       4.4.4.3The integrity checks must identify any discrepancies between the navigation database and the published charts and procedures.

       4.4.4.4If an approved third party performs integrity checks:

(a) discrepancies that invalidate a procedure must be reported to the navigation database supplier; and

(b) affected procedures must be prohibited by an operator's notice to its flight crew.

         Section 4.5 Training programs and operating practices and procedures for CASR 91.5010

4.5.1 Introduction

       4.5.1.1Standardised RNP 4 training programs and operating practices and procedures must be incorporated into existing operator programs and procedures.

       4.5.1.2This section sets out items that the programs, practices and procedures must cover.

       4.5.1.3Some items may already be covered adequately in existing operator programs and procedures.

       4.5.1.4If a new technology eliminates the need for a crew action that this MOS would otherwise require, the MOS may be taken to be complied with in relation to that action.

4.5.2 Flight planning

       4.5.2.1 During flight planning, flight crew must pay particular attention to conditions that may affect RNP 4 operations, including:

(a) verifying that the aircraft is authorised for RNP 4 operations; and

(b) verifying that the ICAO Flight Plan has been correctly annotated (see clause 4.4.2); and

(c) verifying that any additional flight planning requirements specified in ICAO Regional Supplementary Procedures (Doc 7030) or State AIP have been met; and

(d) confirming the requirements for GNSS, such as FDE, for the operation; and

(e) if required for a specific navigation system, accounting for any operating restriction related to the RNP 4 operational authorisation.

4.5.3 Pre-flight procedures

       4.5.3.1The flight crew must:

(a) review maintenance logs and forms to ascertain the condition of equipment required for RNP 4 operations, and clear that maintenance action has been taken to correct defects to required equipment; and

(b) review contingency procedures for RNP 4 operations; and

(c) be able to recognise when the aircraft is no longer capable of navigating in accordance with its RNP 4 operational authorisation.

4.5.4 En-route

       4.5.4.1En-route flight crew must:

(a) check that at least 2 independent long-range navigation systems capable of navigating to RNP 4 are operating normally at entry to the airspace where RNP 4 operations are to be conducted; and

(b) conduct in-flight operating drills and crosschecking procedures to identify navigation errors in sufficient time to prevent aircraft from deviating inadvertently from ATC cleared routes; and

(c) 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.

4.5.5 Flight crew knowledge

       4.5.5.1An AOC holder must ensure that flight crew members have been trained and
