The power management systems on your turboprop provide full control of the engine’s power during all phases of flight. Plus, being aware of your engine’s customized power ratings leads to more durable and cost-efficient maintenance.
Check Manuals for Key Data
The engine manufacturer receives a mission profile that analyzes and establishes component life as well as durability factors such as low cycle fatigue, creep, oxidation and vibration. From this data, customized power settings are determined for Aircraft Flight Manuals (AFMs) or Pilot’s Operating Handbooks (POHs). These documents are essential in managing a turboprop’s power and maintaining its performance, because the settings they contain help pilots correctly position the power lever to deliver the right torque during takeoff, climb, cruise and approach.
Know Your Certified Limits
Turboprops such as the PT6 and PW100 are versatile engines. They are designed to provide maximum takeoff power over a wide range of ambient temperatures so that the engine is not overworked. However, each turboprop performs up to a predetermined, customized thermal rating, which you can find in the AFM and POH.
