ELISE

A priority on landing safely

Airbus is facilitating safer aircraft landings with its advanced ELISE (Exact Landing Interference Simulation Environment) software, which the company is offering to air navigation service providers and airport operators around the globe as an advanced consulting service.

The new-generation technology effectively eliminates disturbances to an airport’s ground-based Instrument Landing System (ILS) signal, which can be sensitive to interference caused by other aircraft, buildings and other objects in close proximity to the runway.

These consulting services offer a step change in accuracy and reliability for ILS signal predictions when compared to existing predicting tools, with the ELISE software’s reliability validated by more than 100 ground and flight measurements performed at several airports.

Additional benefits for airport operations

In addition to raising safety levels during landings – particularly in flying conditions with low or no visibility – ELISE also enables increased runway capacity as well as the optimisation of airside land usage, allowing for “stealth” buildings to be built nearby without disrupting the facility’s Instrument Landing System. 

ELISE was developed by Airbus in partnership with Airbus Group Innovations – the group’s corporate research and development arm – along with France’s Ecole Nationale de l'Aviation Civile civil aeronautics academy. This technology helped determine how to apply “diffraction grating” panels on Airbus’ C65 hangar at the Toulouse-Blagnac airport to prevent the building from scattering signals from the airport’s Instrument Landing System.

In April 2012, ELISE was selected by Poland’s Warsaw Chopin Airport to advance landing operations and increase runway capacities – making it the specialized consulting service’s first customer located in Central and Eastern Europe.
