Embraer's new auto take-off system is presented at a briefing at the Farnborough Airshow.
Embraer is launching a new automated take-off system that will enable its E-Jets to make better use of short runways and would improve payload-range performance.
The Embraer Enhanced Take-Off system (E2TS), part of a range of cabin and performance improvements for the Brazilian crossover jets, has been under development for more than three years and is now patented, Embraer VP engineering and technology Luís Carlos Affonso said during a briefing at the air show Tuesday.
Affonso said the system optimizes the aircraft’s take-off profile and is the first such system in commercial aviation. It will be available from Q4 2025.
E2TS involves a tweak to the aircraft’s flight control system software.
The pilot lines up on the runway, engages autothrottles and selects the E2TS option on the multi-function control display system. The aircraft rotates as normal, but after take-off, increases the pitch angle and achieves the optimum climb profile. Although it is possible for pilots to do this, they cannot achieve the level of precision and consistency of the new system, Affonso said.
Even if an engine is lost, the aircraft can maintain the new angle of climb. “You can gain 250 nm to 500 nm with the same take-off weight” using E2TS, he said. It also allows the aircraft to achieve the standard target of avoiding a 50 ft high obstacle a set distance beyond the end of the runway.
The new system is said to be particularly useful at airports with restricted runways; an E2 taking off from the short runway at London City, for example, will gain 350 nm in range.
