in accordance with section 12.04A of this MOS. For guidance, see also Multi-Part AC 91-32 and AC 139-22 v2.0, Global reporting format – Runway surface condition.

(h) wet snow, being snow that contains enough water content to be able to make a well‑compacted, solid snowball, and from which water will not squeeze out.

       Note   A runway is contaminated when one or more contaminants are present on the surface of the runway.

runway condition assessment matrix or RCAM means a matrix for assessing the runway condition code from a set of observed runway surface conditions and the pilot in command's report on braking action.

runway condition code or RWYCC is the number used in a runway condition report to describe the runway surface condition.

Note   The runway condition code allows the flight crew to make an operational aeroplane performance calculation in accordance with section 12.04A of this MOS. For guidance, see also Multi-Part AC 91-32 and AC 139-22 v2.0, Global reporting format – Runway surface condition.

runway condition report or RCR means a comprehensive standardised report relating to runway surface conditions, and their effect on aeroplane landing and take-off performance.

runway surface condition descriptors: see contaminant.

slippery wet runway means a wet runway where the surface friction characteristics of a significant portion of the runway show that the runway is degraded.

Note   These definitions are for use in relation to Global Reporting Format.

CHAPTER 4 AERODROME REFERENCE CODE AND DETERMINATION OF AERODROME STANDARDS

4.01 Aerodrome Reference Code

       (1) The standards which an aerodrome facility must meet to be suitable for use by aeroplanes within a particular range of performance and size are determined by the aerodrome reference code (ARC) chosen by the aerodrome operator.

       (2) The ARC is made up of 3 elements:

(a) a code number determined by the aeroplane reference field length (code number or runway code number); and

(b) a code letter determined by the aeroplane wingspan (code letter); and

(c) the outer main gear wheel span (OMGWS).

       (3) The aerodrome operator must select from Table 4.01 (3) the code number corresponding to the highest value of the aeroplane reference field length of the aeroplanes which the aerodrome facility is nominated by the operator to serve.

Note   When making a selection, CASA recommends that an aerodrome operator should consider the aircraft types and operations to be accommodated because it is such considerations which dictate the appropriate design, and operating and reporting standards, for the facility.
