The SESAR project is an initiative of the European Union aiming to
modernise and harmonise the European Air Traffic Management (ATM) System
from a technological and operational perspective. It is an essential
component of the broader Single European Sky (SES) initiative. SESAR
contributes to achieving the SES high level performance objectives in
terms of increasing the capacity of current European ATM system, while
reducing their costs and the environmental impact of flights, yet
increasing the level of safety.
