Boeing completed the first flight of the upgraded CH-47F Chinook on 25 June, from its Wilmington, Pennsylvania, factory. Aircraft handling qualities were evaluated during the 5min flight. The CH-47Fprogramme involves fitting a new, lower vibration cockpit section and a Rockwell Collins avionics suite with two 150 x 200mm (6 x 8in) and four 100 x 100mm displays, and two control display units. The airframe has been re-lifed to 5,000h - enough for another 20 years service. The upgraded machines will also be fitted with Honeywell T55-714A engines, offering 25% more power at 4,000ft (1,220m) and 35íC (95íF), plus a low maintenance rotor.
