This is a part of the permanent snow plan applicable for the international airports. The mean friction coefficient will be indicated for each third for the runway. The breaking action will be measured continuously by the Skiddometer, the Surface-Friction-Tester or Tapley-Meter. All friction coefficients are measured and will be given on the basis of the following
0,40 and above | good | Code 5 |
0,39 – 0,36 | medium to good | Code 4 |
0,35 – 0,30 | medium | Code 3 |
0,29 – 0,26 | medium to poor | Code 2 |
0,25 and below | poor | Code 1 |
unreliable | unreliable | Code 0 |

Nautical mile , NM and tenth of it.
1 nautical mile is equal of circle-minute of a great-circle. 1 NM = 1,852 km.
The identification of runway is expressed by numbers which indicate the magnetic direction of the runway.
