A snow plan is not relevant in Malaysia
The following information are based on the implementation of the new ICAO methodology for assessing and reporting runway surface conditions, commonly known as the ICAO Global Reporting Format (GRF). Aircraft operators should utilize the information in conjunction with the performance data provided by the aircraft manufacturer to determine if landing or take-off operations can be conducted safely and provide runway braking action special air reports (AIREP) to ATC.
Runway surface conditions are assessed and reported in the ICAO GRF whenever water is present on an operational runway.
Runway Condition Report (RCR) is disseminated when there are significant changes in the runway surface condition.
The RCR contains Runway Condition Code (RWYCC) and information that describes the runway surface condition, i.e., type of contaminants, depth, coverage for each runway third. Other relevant information is reported in the situational awareness section of the RCR
The RWYCC is derived from the Runway Condition Assessment Matrix (RCAM), which contains the information that is relevant to the current weather environment in Malaysia
Runway condition assessment matrix (RCAM)
Assessment criteria | Downgrade assessment criteria | ||
Runway condition code (RWYCC) | Runway surface description | Aeroplane deceleration or directional control observation | Pilot report of runway braking action |
6 | Dry | - | - |
5 | WET(The runway surface is covered by any visible dampness or water up to and including 3 mm depth) | Braking deceleration is normal for the wheel braking effort applied AND directional control is normal. | Good |
3 | WET(“slippery wet” runway) | Braking deceleration is noticeably reduced for the wheel braking effort applied OR directional control is noticeably reduced. | Medium |
2 | STANDING WATER(more than 3 mm depth) | Braking deceleration OR directional control is between Medium and Poor. | Medium to Poor |
e) The RCR is disseminated via ATIS, SNOWTAM, and Air-Ground Voice Communications.
Communication Channels for RCR
Runway condition code (RWYCC) | Air-Ground Voice Communications | ATIS | SNOWTAM |
6(Dry) | Yes* | No | No** |
5(Wet) | Yes | Yes | No** |
3(Slippery Wet) | Yes | Yes | No** |
2(Standing Water) | Yes | Yes | Yes |
* Upon request
** Except when RWYCC 2 was previously reported
ATIS
The RCR is communicated in addition to the MET REPORT elements. The information is communicated for each runway third in the direction of landing/take-off.
SNOWTAM
The SNOWTAM will be promulgated whenever RWYCC 2 is reported. The assessment and reporting of runway surface conditions continue until the runway is no longer contaminated. The RCR is communicated from the lowest runway designation number
Air-Ground Voice Communications
Only the Runway Condition Code (RWYCC) for each runway third will be communicated through the frequency. The contamination type, contamination depth, and coverage will be provided upon request by the pilot. The information is communicated for each runway third in the direction of landing/take-off
