Difference in payload due to CFM 56 B1 and CFM 56 B2 as fitted to B733F
Need to know the differences in flight performance (speed/payload) due to CFM 56 B1 (20K lbs thrust) and CFM B2/3C1 (22K lbs thrust) fitted to B737-300F/SF. We are considering to uplift 18T payload, will B1 engines help? What would be the best engine type for this amount of payload to fly a range of 1700nm into China? Appreciate genuine advices...
