26.08 Aeroplane IFR flight
       (1) An aeroplane for an IFR flight must be fitted with the following navigation equipment:
(a) for an aeroplane that is manufactured on or after 6 February 2014 — at least 1 approved GNSS but not one authorised in accordance with (E)TSO-C129;
       Note   For approved GNSS, see subsection 1.07 (6).
(b) for an aeroplane that was manufactured before 6 February 2014:
           (i) if the GNSS equipment is installed on or after 6 February 2014 — at least 1 approved GNSS, but not one authorised in accordance with (E)TSO-C129;
           (ii) if the GNSS equipment was installed before 6 February 2014 — at least:
            (A) 1 approved GNSS, but not one authorised in accordance with (E)TSO‑C129; or
            (B) 1 approved GNSS that is authorised in accordance with (E)TSO-C129, and an ADF or VOR.
Note   For aircraft entering oceanic airspace with RNP 2, 4 or 10 navigation specification capability, see subsections 11.03 (1B) and (1C) in relation to long range navigation systems (LRNS) operability requirements.
       (2) If, in accordance with subsection (1), an approved GNSS unit is provided with the automatic barometric aiding options specified in any of the following (the relevant options):
(a) (E)TSO-C129a;
(b) (E)TSO-C145a;
(c) (E)TSO-C146a;

        then the relevant options must be connected.
       (3) Subject to subsection (4), an aeroplane for an IFR flight must be fitted with equipment for measuring and displaying the following flight information:
(a) indicated airspeed;
(b) pressure altitude;
(c) magnetic heading;
(d) time;
(e) Mach number — but only for an aeroplane with operating limitations expressed in terms of Mach number;
(f) turn and slip;
(g) attitude;
(h) vertical speed;
(i) stabilised heading;
(j) outside air temperature;
(k) whether the supply of power to gyroscopic instruments (if any) is adequate.
       (4) For subsection (3), the equipment for measuring and displaying the flight information mentioned in column 1 of an item in Table 26.08 (4) must meet the requirements mentioned in column 2 of the item.
