Two powerplant manufacturers have come to dominate the field among the super midsize jets: Pratt & Whitney Canada and Honeywell. The PW300 family numbers nearly 3,000 in service and has about seven million hours in the logbooks on the Galaxy/Gulfstream G200 and Hawker 4000, while the HTF7000 posts dispatch reliability numbers north of 99% in the Challenger 300 and will power the new Gulfstream G250 and Embraer Legacy 450 and 500.
