Revision 5 – for information only until 30 November 2023

To support the publication of the pending rules on runway condition reporting, which will come into force on 30 November 2023, we encourage participants to refer to the plain and marked up versions of Revision 5 of AC139-3.

Plain version of Revision 5 of AC139-3 [PDF 1002 KB]

Marked-up version of Revision 5 of AC139-3 [PDF 1023 KB]

While this Revision will not come into force until 30 November 2023, we hope that participants will find it helpful to use one or both versions in their preparation for adapting to new runway condition reporting rules by 30 November 2023.  

Please note we are still working with the sector to agree how the necessary software will work in practice. When we have reached decisions on this, we are likely to add sections to this AC and put up an enhanced version of this AC.
