Embraer plans to unveil upgrades to its Ejet regional jet family around the time of the Farnborough air show to demonstrate its commitment to the product line even as it works on defining a new family of regional jets.

The update will lead to improvements in aircraft fuel burn and maintenance performance, says Paulo Cesar de Souza e Silva, president of Embraer’s commercial aviation business. A better health monitoring system would be part of the upgrade.

Meanwhile, the aircraft maker is hoping to see new order bookings in the U.S., with Delta Air Lines and American Airlines seen as potential candidates. Although the Chapter 11 bankruptcy restructuring process at American parent AMR could slow a deal being signed, talks to prepare a contract can go forward.

If any of those deals come through, it would likely provide the impetus to boost output. Deliveries this year are likely to reach 105-110 regional jets, slightly above last year, with order intake at least equal to deliveries.
