Embraer Chief Executive Paulo Cesar de Souza told journalists the business model and financial commitments of the partnership have not been defined. Uber Chief Product Officer Jeff Holden said last month that a paid, intra-city flying taxi service could start in 2023.
Souza said the companies would soon determine specifications of the proposed vertical take-off and landing (VTOL) aircraft.
Engineers are projecting one-tonne vehicles transporting a pilot and four passengers at an altitude of 800 to 1,000 meters (2,600-3,300 feet), Souza said. The aircraft will be powered by batteries that can charge in as little as five minutes between flights, he added.
The project has provided an outlet for engineering resources at Embraer, whose newest planes - a military cargo jet and a new generation of passenger jets - are well into their flight testing campaigns.
The transition to a new commercial jet line-up is pressuring operations, but Souza said Embraer would meet the bottom end of its 2017 profit margin and aircraft delivery targets.
