Honeywell FX5

The Honeywell FX5 was a 6,000lb-thrust (27kN) geared turbofan based on a technology demonstrator core. Aiming for a 20%-plus reduction in cost of ownership from the TFE731-60 and to span a 3,000 - 8,000 lbf family, it could have been certificated within 36 months. It was proposed for the Dassault Falcon 7X business jet launched in 2001, but the Pratt & Whitney Canada PW307 was finally selected. The Honeywell range comprises the previous 6,700 - 7,500 lbf Lycoming ALF502/Honeywell LF507 and the subsequent 6,540 - 7,550 lbf Honeywell HTF7000.
