A major part of the modification for both the Mk4/4A and Mk5 aircraft is the Thales TopDeck cockpit. Thales UK is under contract with Boeing to supply its Cockpit Display System/Mission Avionic System, which will provide improved situational awareness, increased safety and options for capability enhancement. The upgraded and integrated cockpit display includes four multifunction displays, two stand-by flight displays, updated communications interfaces, and two new air data computers. 

"The first of the modified JULIUS Chinook helicopters is expected to be available to commanders before the end of 2011," said David Pitchforth, managing director, Boeing UK Rotorcraft Support. "The entire Mk2 fleet will be fitted with the JULIUS cockpit by early 2015, followed by Mk2A and Mk3 modifications by 2015 and 2016, respectively." 

The modifications also include the addition of a third crew-member seat and an update of Airworthiness & Safety Certification and Qualification for the modernized Chinook. The aircraft are being modified at the Gosport Fleetlands facility operated by Vector Aerospace, Boeing's principal subcontractor for deep support of the RAF Chinook fleet. Vector Aerospace has established a dedicated production line at Fleetlands to support the JULIUS program, with specialist component manufacture provided from its Almondbank facility near Perth, Scotland. 

"Vector Aerospace is delighted to be associated with this significant milestone. It is a testimony to the skill and dedication of our teams in Fleetlands and Almondbank, who have worked in a spirit of true partnership with our customer Boeing and the key equipment suppliers," said Tim Rice, managing director, Vector Aerospace UK.
