  3. Workshop background (1/3) • The future operations of new large aircraft (e.g. A380) in Low Visibility Conditions have raised some concerns in past five years • Are the current practices based upon the vacation of ILS sensitive area before a landing still valid with these new aircraft? • Are wider sensitive areas necessary? • Are existing propagation signal model appropriate?

  4. Workshop background (2/3) • Several studies have been conducted to assess the effect of such new large aircraft on the ILS signal performances • They were based upon various simulation models and the results were not necessarily coherent • There is a general agreement on the fact that a sophisticated simulation model should provide results closer to the reality • This situation has generated a lot of debate regarding the validity of simple simulation model to really assess those impact and the fact that such validity could be scenario dependant

  5. Workshop background (3/3) • As a result of the concerns expressed before, a common project has been launched by the several aviationstakeholders to address this issue by conducting several measurement campaigns with an A380 • The partners are: ANSPs (DFS, DSNA, LVNL and NATS), Airport operators (Fraport, BAA), Airbus and several experts in simulation tools and methods • The results of this project are presented in this workshop

  6. Workshop objectives • To provide a first assesment of the impact of new large aircraft on ILS sensitive areas based upon field measurements • To provide results of correlation between field measurements and simulations results to validate propagation and A380 models
