and ceiling, less than the minimum specified for visual meteorological conditions.

instrument runway means 1 of the following types of runway nominated for the operation of aircraft using instrument approach procedures:

(a) non-precision approach runway, being a runway, served by visual aids and non‑visual aids, intended for landing operations following an instrument approach operation with a minimum descent height or decision height (DH) at or above 250 ft (a type A operation) in runway visibility of not less than 1 000 m;

(b) precision approach runway, Category (CAT) I, being a runway, served by visual aids and non-visual aids, intended for landing operations following an instrument approach operation with a DH lower than 250 ft (a type B operation) but not lower than 200 ft, and either:

 (i) in visibility of not less than 800 m; or

 (ii) with an RVR of not less than 550 m;

(c) precision approach runway, Special Authorisation Category I (SA CAT I), being a runway, served by visual aids and non-visual aids, nominated for landing operations following an instrument approach type B operation with a DH lower than 200 ft but not lower than 150 ft, and an RVR of not less than 450 m;

(d) precision approach runway, Special Authorisation Category II (SA CAT II) being a runway, served by visual aids and non-visual aids, nominated for landing operations following an instrument approach type B operation with a DH lower than 200 ft but not lower than 100 ft, and an RVR of not less than 350 m;

(e) precision approach runway, CAT II, being a runway, served by visual aids and non‑visual aids, nominated for landing operations following an instrument approach type B operation with a DH lower than 200 ft, but not lower than 100 ft, and an RVR of not less than 300 m;

(f) precision approach runway, CAT III, being a runway, served by visual aids and non‑visual aids, for landing operations following an instrument approach type B operation to and along the surface of the runway and:

 (i) for CAT IIIA — nominated for operations with a DH lower than 100 ft or with no decision height, and an RVR of not less than 175 m; and

 (ii) for CAT IIIB — nominated for operations with a DH lower than 50 ft or with no decision height, and an RVR of less than 175 m but not less than 50 m; and

 (iii) for CAT IIIC — nominated for operations with no DH or RVR limitations.

Note 1   Instrument approach procedures are classified as follows:
       (a) Non-precision approach (NPA) procedure: an instrument approach procedure designed for 2D instrument approach type A operations.
       (b) Approach procedure with vertical guidance
