Aviation Communication and Surveillance Systems (ACSS), an L-3 and Thales company (Booth C8145), is reminding NBAA 2015 attendees that the European Aviation Safety Agency (EASA) mandate for aircraft using its airspace and services to upgrade to TCAS II Change 7.1 is December 1.

“The Change 7.1 upgrade delivers important enhancements to TCAS, including reversal logic, new aural alerting for Adjust Vertical Speed, and Level-off resolution advisories. A lot of operators should want this upgrade even if they don’t fly to Europe,” explained Shane LaPlante, vice president of aftermarket sales for ACSS and L-3 Aviation Products.

The 7.1 upgrade is available from ACSS for all of its TCAS products through the L-3 dealer network and major OEM service centers worldwide. ACSS products include TCAS II, TCAS 3000 /SP, T2CAS and T3CAS.
