Rescue and fire fighting services
At aerodromes approved for scheduled and/or non-scheduled traffic, Rescue and Fire Fighting Services are established in accordance with the regulation for civil aviation.
Information about whether there is service and what the extent of that service is, is given on the relevant page for each aerodrome.
Snow plan
Organization of winter service
During the winter period from approximately 1 November to approximately 1 April, winter service is established at the aerodromes.
Measuring methods and measurement taken
The runway surface friction measurements will be carried out under the following circumstances:
The wet and slippery runway
The runway are wholly or partially covered with snow and ice.
The friction of runway surface coefficients are measured with Mu-meter or SFT(surface friction) along a line on each side of the center line of the runway approximately 3 - 6M.
With the MUM(Mu-meter) and SFH(Surface friction Tester(high pressure tire)), the braking action will be measured continuously at a speed of 65KM/h or 95 KM/h.
Report of Estimated Surface Friction
The table of friction coefficients is as the following table.
Measured coefficient |
Estimated Surface Friction |
Code |
---|---|---|
0.40 and above |
Good |
5 |
0.39 to 0.36 |
Good to Medium |
4 |
0.35 to 0.30 |
Medium |
3 |
0.29 to 0.26 |
Medium to Poor |
2 |
0.25 or below |
Poor |
1 |
For the purpose of reporting braking action by ATS, each runway, divided into three section, will be referred to as “First”, “Second”, or “Third” part of a runway as seen in the direction of landing. If the friction coefficient values for any of the runway are reported below 0.4, the estimated braking action will be notified to pilots. The information will also be disseminated by ATS through the ATIS broadcasts and NOTAM.
Measures for improvement of Surface Friction
In order to clear of runway, taxiway and apron, snow blower/sweeper and snow ploughs will be used for removal of snow, ice, slush and standing water. Thin ice covering on runway will be removed by means of chemical de-icing.
Dissemination of information about snow conditions
Information on snow conditions at aerodromes will be disseminated directly from the individual aerodrome in a separate series of NOTAM (SNOWTAM). SNOWTAM will be prepared in accorance with ICAO ANNEX 15.
