Provide updated databases including aeronautical information and geographical data on LFPG and LFPO. These databases will be shared by DSNA and airports operators and will be used in a collaborative way on LFPG and LFPO. Use databases for procedure design and cartographic needs on LFPG and LFPO. DSNA and airports operators will use the databases for their respective needs (procedure design, cartography...). For these needs, existing tools will be updated and a common AIM Tool used by local DSNA units and airports operators at LFPG and LFPO will be developed to enhance the collaboration between ANSP and Airport operator in the AIM domain and to enhance aeronautical publication on these airports.
