Embraer underlines safety aspects of automatic rotation and take-off system

Embraer has emphasised the safety aspects of its automatic take-off system, as it prepares for European and US certification measures. The system – known as E2TS – has already been fitted to an E195-E2, but the manufacturer intends to make it available across its E-Jet range. It is designed to optimise take-off by rotating the aircraft consistently, pitching it sufficiently to avoid tail-strike before increasing pitch, immediately after becoming airborne, to gain height and reduce overall take-off distance. Embraer’s E2TS technical leader, Patrice London Guedes, says it uses the fly-by-wire architecture, including three flight-control computers and four air-data sensors, for the “highest level of integrity and availability”. The ability to pursue a greater pitch after leaving the ground translates to increased take-off weight capability. London Guedes adds that the system is “fail passive”, disengaging with no significant deviation and reverting to pilot control after a single failure. “Beyond the take-off performance optimisation, the system will greatly improve safety, by reducing the pilot workload and making the operation even more precise and consistent,” he says.<br/>
