Embraer is working on an extended version of those planes but needs to work out an auto-take-off measure that prevents tail strikes.
Automatic takeoffs are coming for passenger jets and they’re going to redraw the map of the sky
Today, automatic landing systems are installed on most commercial aircraft and improve the safety of landings in difficult weather or poor visibility.
Now, nearly 60 years later, the world’s third largest aircraft manufacturer, Brazil’s Embraer, is introducing a similar technology, but for takeoffs.
Called “E2 Enhanced Take Off System,” after the family of aircraft it’s designed for, the technology would not only improve safety by reducing pilot workload, but it would also improve range and takeoff weight, allowing the planes that use it to travel farther, according to Embraer.
“The system is better than the pilots,” says Patrice London, principal performance engineer at Embraer, who has worked on the project for over a decade. ”That’s because it performs in the same way all the time. If you do 1,000 takeoffs, you will get 1,000 of exactly the same takeoff.”
Embraer, London adds, has already started flight testing, with the aim to get it approved by aviation authorities in 2025, before introducing it from select airports.

Crucially, the system allows the plane to take off as early as possible and more steeply, but without ever incurring a tail strike — a dangerous situation in which the tail of the plane touches the runway or an obstacle as the aircraft lifts off, sometimes as a result of pilot error.
“If you’re a pilot, you have to give some room for error,” says Affonso. “But because this system is so precise and consistent, you don’t need the same margins and you can operate closer to the optimum in the initial rotation, as if you were closer to touching with the tail. Except you will not.”
Embraer says this optimization allows for an increase in takeoff weight, which means either more passengers or more range — up to 350 nautical miles. This opens up destinations that are precluded with the same combination of airport and aircraft, but without the automated takeoff system.
