Honeywell Aerospace, the United States-based aviation parts maker and a major supplier to China's domestic commercial aircraft, the C919, is upbeat about the much-anticipated jet's maiden flight in 2015, a senior executive of the company said.

"We are on schedule" with the Commercial Aircraft Corp of China's plan for the first flight, John Bolton, president of the air transport and regional strategic business division at Honeywell Aerospace, told China Daily during the Paris Air Show, which opened on Monday.

"Our products continue to progress and mature. And we are looking forward to a successful first flight in 2015," he said.
