Pratt & Whitney Canada PW127
PW127 is Pratt & Whitney Canada's PW100-series regional turboprop model. EASA's current type-certificate sheet lists 2,051 kW maximum take-off shaft power, 1,846 kW normal take-off power, and 1,864 kW maximum-continuous power at sea level. Pratt & Whitney describes the PW100 architecture as a three-shaft turbomachine with a two-spool compressor system, a free power turbine, and reduction gearbox; the canonical model remains distinct from later PW127 suffix variants and individual ATR installations.
