Fuel consumption is a PITA because official figures aren't published. But we can work backwards towards it. PW suggests a 16% reduction against a CFM-56 benchmark, and Aviadvigatel suggest a 10% reduction against a CFM-56 benchmark.

- For apples to apples, we will use the average of 737-700 & A319 CFM-56 fuel burn to compare to the MS-21-200, as they are the closest approximations in size.
- 737-700 with CFM-56 average consumption: 2505 kg/hr
- A319 with CFM-56 average consumption: 2235 kg/hr
- Average of A319/737 fuel consumption: 2370 kg/hr
- PW-1400 16% decrease in fuel consumption rounded to nearest 5: 1990 kg/hr
- PD-14 10% decrease in fuel consumption rounded to nearest 5: 2135 kg/hr
MS-21-300 Fuel Consumption Calculation
- For apples to apples, we will use the average of 737-800 & A320 CFM-56 fuel burn to compare to the MS-21-200, as they are the closest approximations in size.
- 737-800 with CFM-56 average consumption: 2545 kg/hr
- A320 with CFM-56 average consumption: 2445 kg/hr
- Average of A320/738 fuel consumption: 2495 kg/hr
- PW-1400 16% decrease in fuel consumption rounded to nearest 5: 2095 kg/hr
- PD-14 10% decrease in fuel consumption rounded to nearest 5: 2245 kg/hr
Both of these figures are consistent with the NEO/Max performance improvements over the standard A320/737 series.
