Jet Aviation develops EASA STC for upgraded TCAS

 Any aircraft equipped with TCAS II version 7.0 software and operating within European Union airspace must upgrade to version 7.1 by December 1, 2015.

The Swiss company’s Basel operation now has an STC approved by EASA for the TCAS II version 7.1 upgrade. TCAS II provides vertical rate "Resolution Advisories" (RAs) to pilots, informing them when and how to adjust their vertical speed
in order to avoid collisions. All aircraft manufactured since March 2012 are equipped with TCAS II version 7.1.

The TCAS II version 7.1 upgrade improves flight safety by correcting an issue with the TCAS reversal logic in the event that one of the alerted crews does not comply with a resolution advisory or initiates an opposite manoeuvre. The upgrade also replaces several confusing “Adjust Vertical Speed” RAs with a single “Level Off” RA.

“To ensure easy installation of this state-of-the-art software, we are offering the TCAS version 7.1 STC upgrade alone or in combination with a full service installation at Jet Aviation Basel or any other Jet Aviation facility,” said Johannes Turzer, vice president and general manager at Jet Aviation Basel. “Our dedicated off site service team can also install the upgrade in any hangar of the customer’s choice worldwide.”
