Final approach improvements with conventional navaids rationalization while maintaining performance levels. Advanced techniques like APV&LNAV and Precision Tactical Clearance for TMA operations. SESAR concept integration for environmental and efficiency improvements. ATC utilizing conflict detection tools for better management of air traffic. Future considerations for Free Route development and PBN implementation. Multiconstellation requirements for robust RNP. Emphasis on fleet equipage to maximize PBN benefits in busiest TMAs.

DSNA needs & Policy • Final approach • ConventionalNavaids rationalisation whilemaintaining the samelevel of performance • -> APV&LNAV • Terminal Area • SID/STARswithturning legs for environmentalimprovements & shortertracks • SESAR concept & PrecisionTactical Clearance = RNP for TMA operations • -> RF capability & Advanced RNP (1NM TSE) & RNAV holding • -> VNAV ? • En-Route • Free-route development. ATC keeps an eye on trafic through « conflictdetectiontools » (CDT) The betteraircraft performances we have, the better CDT resultsweget • Turning legs for the remainingfixed route network • -> What PBN for the various steps of FreeRouting and for its long terms targets? • -> RF or FRT for En-Route ? • General • Multiconstellationwillbeneeded for a robust RNP • ATC need a very large percentage of the fleet to beequipped to provide PBN benefits in the busiest TMA/Approaches • -> As few mandate exemptions as possible
