"We don't have a lot of standard content on the existing 777, so I think our opportunities to gain share are pretty significant on the 777X," Rockwell Collins Chief Executive Kelly Ortberg told a Credit Suisse conference that was broadcast via Internet.
Ortberg said Boeing was determining how much of the current 777 widebody airplane might be changed. Should the jetmaker decide to use systems on the new jet similar to those on Boeing's 787 Dreamliner, he said Rockwell would have a greater opportunity to supply the 777X.
Rockwell Collins supplies avionics systems for the 787.
Ortberg also said the aviation electronics supplier expected to know what content the company might have on the 777X by late spring or early summer 2014.
The 777X, a widebody jet designed to carry up to 406 people on long-haul routes, may enter commercial service by 2020.
