Aeroderivative Gas Turbine M250-Turboprop
The M250 turboprop has found popularity due to its small size and high power-to-weight ratio, which make it ideal for Original Equipment Manufacture Type Certified designs and for Supplemental Type Certificate conversions of existing piston-engined designs. These lightweight, high power engines operate on all certified aircraft fuels, a feature favoured by operators who take them into remote regions of the world. Their legendary reliability, combined with vibration free turbine smoothness, gives an easy ride to both the passengers and the airframe components. Cabin noise levels can often be cut by over 10 dBA, enabling pilots and passengers of M250 turboprop powered aircraft to converse at normal levels, without headsets.
