SYSTEM AND METHOD FOR OPERATING A TURBOPROP ENGINE

A method (800) and system for operating a turboprop engine (110) of an aircraft comprise obtaining at least one upper limit (402, 502, 606, 610) and at least one lower limit (404, 504, 608, 612) on a gas generator speed (Ng) of the turboprop engine (110) and receiving a target power for the turboprop engine (110). When a resulting value for Ng is between the at least one upper limit (402, 502, 606, 610) and the at least one lower limit (404, 504, 608, 612), the output power is governed as a function of the target power. When the resulting value for Ng is on or outside of the at least one upper limit (402, 502, 606, 610) and the at least one lower limit (404, 504, 608, 612), the output power is governed as a function of the maximum Ng and the minimum Ng.
