HIgh Stability VErtical SeparaTion Altimeter instruments


The strategic objective of the project is to increase the safety in all in-flight situations, particularly low visibility situations, by improving the altimetry transducers used in Air Data Computers for aircraft applications. The project is relevant in auto pilot situations in the reduced vertical separation minima legislation of 1000ft, as well as in demanding manual flying situations such as darkness and low visibility. Used in enhanced transponder applications, the project will contribute to significantly increased reliability in altitude information for manual and automated Air Traffic Control systems. Aircraft Traffic Collision Avoidance Systems will also benefit from more accurate and reliable altitude information, which will allow the automated avoidance instructions to be more accurate and effective. HISVESTA is the next step in solving the remaining RTD challenges after the successful HASTAC project in FP6. The project will develop a new generation of altimetry module, suitable for fixed wing and rotary wing applications, which will give altitude accuracy capabilities significantly improved over those currently available today. Air Data Computer and aircraft flight testing performed in the project will demonstrate the effectiveness of the performance improvement. A key HISVESTA target is for the European avionic system industry to regain the market lead in altimetry and automatic ATC solutions as well as in altitude pressure transducers with best in class long-term stability. Another project objective is to contribute to reduction of the emission of CO2 and NOx significantly in the next generation jet Engines, by improving the multifunctional pressure control system in the Full Authority Digital Engine Control systems. This initiative consists of a strong consortium of European SMEs and participants from new member states. The entities in the Consortium have worked together successfully in the past; enhancing the probability for success.
