Motivation for HISVESTA f • After introduction of RVSM (Reduced Vertical Separation Minimum) to 1000ft altitude separating aircrafts flight levels a number of incidents are reported were passenger separating aircrafts flight levels, a number of incidents are reported were passenger aircrafts are violating the tolerances of altitude accuracy. • The specific Altimetry conference held in Brussels August 2010 by EuroControl, “Altimetry System Error, The invisible Risk” clearly showed that improved procedures and more accurate altitude equipment are needed to secure safe flight operation • HISVESTA project concentrates on Research and Development of altimetry sensors with higher accuracy and better long term stability performance than what is currently available • Additional Motivation: To utilize the R&D results from Altimetry sensor project to develop pressure sensing products suitable for Jet Engine FADECs (Full Authority Digital Engine pressure sensing products suitable for Jet Engine FADECs (Full Authority Digital Engine Control) for high temperature operation, to reduce fuel consumption, reduce emission of CO 2 and NOx HISVESTA is carried out with support from European Commission Framework 7 Theme 7 - Transport- 4 Aeronautics
