Pratt & Whitney announced yesterday that its PW4000-100 engine with the Advantage 70 upgrade completed its first test flight aboard an Air Comet A330-200 in Toulouse. The test program will continue through early April. The PW4000-100 is designed to deliver 70,000 lb. thrust for the A330 and will enter revenue service on the Air Comet -200 and an Air Caraibes A330-300 in the summer.
