This year over 1,000 employees will once again be involved in winter service operations at Paris-CDG Airport.

Providing the winter service (WS) for the CDG airside areas requires setting up a Snow Plan as part of our overall organisation involving all the stakeholders in the winter maintenance of Paris-CDG.

This document is published every year in October and is for all those involved in WS as well as Groupe ADP partners (Air Navigation Service, airlines, CDGR Winter Maintenance Department service providers, the Operational Unit for CDG airside areas, etc.). It describes in detail the winter processes involved during a winter aviation season, particularly the different intervention strategies.

“The obligation to maintain our expertise requires a tremendous amount of organisation, logistics and training.”  Régis Lacote, Director of CDGR Airside Operations and Facilities

CDM, the primary process

The Snow Plan is implemented collectively. It is consistent with the CDM (Collaborative Decision Making) approach, and as such is a key component even of a collaborative circle between all the players involved in WS operations.

The CDM is structured around daily or intermittent audio-conferences during which available information is shared between all the participants and decisions are made regarding the strategies and tactical solutions each of them has planned (CDM platform).

The CDM platform centralises and makes decisions on how to manage any deteriorating situation.” Jean-Marc Flon, SNA – RP
