B1900d fuel capacity3/12/2024 I believe the Metro family also burns less fuel to haul 19 people around, but in considerably less comfort. The PW118 on the E120 is a three spool design, with two power turbine stages, delivering better specific fuel consumption, but at the cost of considerable weight and complexity. Some of the difference is the engine, the PT6 is only a two spool engine, so all 1275 SHP have to be extracted from the one power turbine stage, that just requires alot of gas flow. At FL280 you could bring the fuel flow down to match the Beech, 800lbs/hr, and be 20kts TAS faster with more than half again as many people. The Emb-120, for example, carries 11 more people on only 20% more fuel burn, most of which was in the climb. There are airplanes that will burn less fuel. There were no complaints regarding engine life from our mx department nor our engine vendor. We climbed at Max Continuous Torque, and once limited by temperature climbed at ITT 760C, cruise between 730-760C. I guess I should qualify my reply in that that was real world values, and setting "company" power, not book settings.
