5 operations, for example, the AFM, the AFMS or OEM service letters.

3 RNAV 5 system performance
       3.1 For RNAV 5 eligibility, an aircraft's navigation system (the system) must meet the performance, monitoring and alerting requirements for RNAV 5 operations as stated in ICAO Doc. 9613, Performance-based Navigation (PBN) Manual, Volume II, Part B, Chapter 2, Implementing RNAV 5.
       3.2 If GNSS is used for an RNAV 5 operation, positioning data from non‑GNSS navigation sensors may be integrated with GNSS data if:
(a) the non-GNSS data does not cause position errors exceeding the TSE limit; or
(b) if paragraph (a) cannot be complied with — there is a means to deselect the non‑GNSS inputs.

4 RNAV 5 system functionality
       4.1 For RNAV 5 eligibility, the system must meet the following minimum standards of functionality:
(a) the aircraft position relative to track must be continuously displayed on a navigation display situated in the primary field of view of the pilot flying the aircraft;
(b) where the minimum flight crew is 2 pilots, the aircraft position relative to track must also be continuously displayed on a navigation display situated in the primary field of view of the pilot not flying the aircraft;
(c) the system must display distance and bearing to the active (to) waypoint;
(d) the system must display ground-speed or time to the active (to) waypoint;
(e) the system must store at least 4 waypoints;
(f) the system must indicate failure of the system, including the sensors.
       4.2 The following standards apply to navigation displays:
(a) navigation data must be available on:
 (i) a display forming part of the RNAV equipment; or
           (ii) a lateral deviation display, for example, CDI, (E)HSI, or a navigation map display;
       (b)      the display must be suitable for use:
 (i) as the primary flight instrument for navigation of the aircraft; and
 (ii) for manoeuvre anticipation; and
 (iii) for failure, status or integrity indication;
(c) the display must be visible to the pilot when looking forward along the flight path;
(d) where a lateral deviation display is implemented, the lateral deviation display must have:
 (i) scaling compatible with any alerting and annunciation limits; and
 (ii) scaling and full-scale deflection suitable for RNAV 5 operations.

5 RNAV 5 equipment
       5.1  For RNAV 5 eligibility, an aircraft's navigation equipment must:
(a) enable the aircraft to establish and follow a desired flight path; and
(b) automatically determine the aircraft's position in the horizontal plane using inputs from 1 or more of the following types or combinations of position sensors:
 (i) VOR/DME;
 (ii) DME/DME;
 (iii) INS or IRS;
 (iv) GNSS.
       5.2 If an aircraft is not equipped with GNSS, it must, nevertheless, have the capability to satisfy the RNAV 5
