Flying to Europe? Don't Forget to Pack your TCAS 7.1 Upgrade

With the December 2015 European Union mandate quickly approaching, operators flying in EU airspace are well-advised to get their aircraft updated at the earliest opportunity to avoid possible end-of-year installation capacity issues.

While implementation of TCAS has had a significant beneficial impact on aviation safety since initial government-mandated implementations began in the mid-1990s. the essential model continues to evolve as a result of further study of accidents, leading to refinements, training and regulatory mandates.

Spurred by a series of incidents in 2001 and 2002, two primary safety-related issues are addressed in the latest version, Change 7.1. One change (CP 112E) corrects an issue with TCAS-TCAS reversals. The other (CP 115) changes the current TCAS II aural warning “Adjust Vertical Speed, Adjust” to “Level Off, Level Off.”

TCAS Reversals

Honeywell’s TPA-100B Change 7.1-compliant design meets the challenge for its broad base of airline and business aviation customers with solutions that not only meet the mandate requirements but provide a number of benefits ranging from fuel savings, greater situational awareness, fewer delays and expensive aircraft-on-ground (AOG) situations.

Jet Aviation, one of the leading business aviation services companies in the world, recently completed supplemental type certifications (STCs) on the Dassault Falcon 20 and Learjet 31 and Germany-based Aero-Dienst completed certification for the Learjet 35/36.

For owners of the Bendix/King (Honeywell) CAS-67A processor, Pro Star Aviation has developed an STC to address the EASA mandate. In December 2014, The FAA issued an approved model list (AML) STC to Pro Star for upgrade of BendixKing CAS 67A Change 7.0 to CAS 67B Change 7.1 for operators of many popular business aircraft including various Beech, Boeing® , Bombardier®, Cessna, Dassault®, Gulfstream®, Learjet, Lockheed and Sabreliner models. STCs are in progress for the other affected platforms.

Operators and dealers can contact their BendixKing sales representative for more information about STC ST00347BO and to get a list of approved models.
