Safety issue description

There was no regulatory direction from the Civil Aviation Safety Authority on how a damp runway was to be considered for aircraft landing performance.

Proactive Action

Action number: AO-2015-046-NSA-009
Action organisation: Civil Aviation Safety Authority
Date: 18 September 2018
Action status: Monitor

In response to this safety issue, the Civil Aviation Safety Authority advised that the International Civil Aviation Organization has already harmonised its runway condition definitions across all relevant Annexes and Documents (Docs) for the pending implementation of a globally harmonised methodology for runway surface condition assessment and reporting. The new methodology is scheduled to become effective in 2020. The new definitions remove any reference to damp as a separate runway condition, and explicitly introduce ‘dampness’ under the ‘wet’ runway condition.

The Civil Aviation Safety Authority is committed to closely harmonising its regulations with the International Civil Aviation Organization. Considering the regulatory development process the Civil Aviation Safety Authority is currently undertaking, it is their preference to align the relevant runway condition definitions with International Civil Aviation Organization, and at which time they will consult industry accordingly.
