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 CO2 and NOx

Research results for new altimetry sensors

The HISVESTA project was officially started in January 2009 and has 30 months duration.

HISVESTA is targeting better altimetry pressure sensors for altimeters, Air Data Computers and Auto Pilot systems Sea level 1013,25 mbar A 18,000 ft 500mbar A 29,000 ft 315mbar A 29,000 ft 315mbar A 41,000 ft 178mbar A
