Abstract	The availability of the LHC ADT and RF systems in 2017 is presented in details, including high-and low-power RF and RF controls. A comparison with 2016 availability is performed. The full-detuning scheme, commissioned early this year, has been operational throughout the year and the first experience with this scheme is summarised. New operational diagnostics, implemented in 2017, are shown as well. Finally, the latest findings from beam dynamics studies and measurements, which have implications for the operation today and in the near future, are highlighted.
