ED Decision 2021/003/R
ASSESSMENT OF ACHIEVED RESULTS
The operational objectives are aligned with the need to establish a runway surface at least with friction characteristics commensurate with RWYCC 4. This could mean a need to apply materials (sand, grit or chemicals) and to assess whether frozen sand can be applied.
If it is assessed that the treatment (frozen sand or other method) has not achieved the desired results (i.e. at least the equivalent of RWYCC 4), a specially prepared winter runway is reported with the appropriately downgraded RWYCC, and in the RCR free text field, the word ‘DOWNGRADED’ is used.
Depending on the actual weather and traffic conditions, the continuous monitoring and assessment of the achieved results may be carried out by the same staff operating the equipment for surface treatment or by staff operating an independent vehicle in contact with the equipment operator.
