Cobham said its board's expectations for group performance in 2017 remained unchanged.
But it said that as previously stated, a range of potential outcomes for full year performance remained and, as in prior years, this included a significant level of trading activity in the final two months of the year.
Th group said its performance in the first 10 months of 2017 had been largely as expected.
An update said: 'Cobham has continued to build the foundations for its future success through the implementation of a challenging turnaround in its performance.
'This turnaround includes arresting and reversing the group's negative performance trajectory and the resolution of onerous contracts, including the KC-46 tanker programme, and other legacy issues.
'The group is continuing to focus on its three operational priorities of: (1) customer focus, (2) leadership and simplification and (3) control and execution.'
It said the strategic review of its Wireless and AvComm business units was ongoing and an update would be provided in due course.
