lateral TSE must be within ±1 × RNP of the path defined by the published procedures for at least 95% of the total flight time for each phase of flight and each autopilot and/or flight director mode requested.

6 RF path terminator system functionality
       To meet the requirements of clause 4 above, an eligible aircraft's RF path terminator system must have the following functionality:
(a) an autopilot or flight director with at least "roll-steering" capability that is driven by the RNP system. The autopilot/flight director must operate with suitable accuracy to track the lateral and, as appropriate, vertical paths required by a specific RNP procedure;
(b) an electronic map display depicting the RNP computed path of the selected procedure;
(c) the flight management computer, the flight director system, and the autopilot must be capable of commanding and achieving a bank angle up to 25 degrees above 400 feet AGL;
(d) the flight guidance mode should remain in LNAV while on an RF Leg, when a procedure is abandoned or a missed approach/go-round is initiated (through activation of TOGA or other means) to enable display of deviation and display of positive course guidance during the RF Leg. As an alternative means, crew procedures may be used that ensure that the aircraft adheres to the specified flight path throughout the RF Leg segment.

7 Operating standards
       7.1The standards for the conduct of RF path terminator operations are as follows:
(a) RF path terminator operations must be conducted in association with RNP 1, RNP 0.3, RNP APCH or A-RNP operations;
(b) when the intended route includes flying an RNP route with an RF Leg, the RNP system and autopilot/flight director must be operational on despatch;
(c) the route must be retrieved from the aircraft navigation database and conform to the charted procedure;
(d) the lateral path must not be modified except when complying with ATC clearances/instructions;
(e) the pilot must use either a flight director or autopilot and comply with any instructions or procedures identified by the manufacturer as necessary to comply with the performance requirements in this Appendix;
(f) the aircraft must be established on the procedure or route before beginning the RF Leg;
(g) where published, the pilot must not exceed maximum airspeeds associated with the fly-ability (design) of the RF Leg.
       7.2Route centrelines must be maintained as close as practicable unless authorised to deviate by ATC or under emergency conditions. Navigation System Error + Flight Technical Error (lateral deviation) must not exceed the specified navigation accuracy.

8 Flight crew knowledge and training
       An RF path terminator operation may only be commenced if each member of the flight crew has knowledge of, and approved training in, how to safely conduct an
