Denis Huet is the head of the Aviation Intelligence Unit in EUROCONTROL. He is in charge of leveraging the data in EUROCONTROL with the view to inform the aviation community and in particularly its decision makers.

As part of his portfolio, he leads the Performance Review Unit (PRU) in its support to the Performance Review Commission (PRC). He is also in charge of EUROCONTROL traffic forecasts (STATFOR) as well as the Central Office of Delay Analysis (CODA) and Cost Benefit Analysis for SESAR, the R&D part of the Single European Sky.

Denis Huet started as Deputy Head of the Air Navigation Charges Bureau in the French DGCA from 1996 to 2001. He moved to the European Commission in 2001 until 2006 as national expert in the Single Sky Unit, in charge of setting up both the SES charging and performance schemes. He then moved to EUROCONTROL as Head of the Projects Office of the Performance Review Unit until 2013, in charge of supporting the Commission in the development and management of the SES performance scheme. He then spent 3 years as Senior Expert in the Airport Research Unit of Eurocontrol until September 2016, in charge of the development of the performance aspects of the Airport Operations Center (APOC) concept. He became Head of the Economic Performance Review Unit in October 2016, supporting both the Performance Review Commission and the European Commission. Since January 2020, he leads the Aviation Intelligence Unit.
