Embraer Phenom 100 gains new airborne awareness systems

Saturday, October 23rd, 2010

Embraer has certified a new Traffic Alert and Collision Avoidance System (TCAS) and a Traffic Awareness and Warning System (TAWS) for its entry level Phenom 100 executive jet. These systems are now standard options for Phenom 100 customers. TCAS II will be supplied by Aviation Communications and Surveillance Systems (ACSS), and TAWS A by Garmin.

TCAS is an airborne system that operates independently from ground-based Air Traffic Control (ATC). It was designed to increase cockpit awareness of approaching aircraft, and to serve as a “last line of defense” to prevent mid-air collisions. TCAS I was developed to accommodate the needs of the general aviation community and regional airlines. This system issues Traffic Advisories (TA) to assist pilots in the visual acquisition of intruder aircraft. TCAS II is a more sophisticated system that provides all of the information of TCAS I, analyzes the projected flight path of approaching aircraft, and issues Resolution Advisories (RA) to the pilot to resolve potential mid-air collisions.

TAWS aims to prevent Controlled Flight Into Terrain (CFIT) accidents and displays terrain and obstructions relative to the altitude of the airplane. TAWS A is an enhancement to the TAWS B, which was originally available to Phenom 100 customers. TAWS A includes all of the requirements of TAWS B, and adds three alerts – closure rate to terrain, flight into terrain (when not in landing configuration), and downward deviation from an ILS (Instrument Landing System) glide slope – increasing flight safety for aircraft operators.
