What is the difference between FADEC and EEC?
When standing alone, the EEC makes all of the decisions until the pilot wishes to intervene. FADEC works by receiving multiple input variables of the current flight condition including air density, throttle lever position, engine temperatures, engine pressures, and many other parameters.
What does a FADEC do?
FADEC combines throttle, prop, and mixture controls into a single control. Every throttle setting at any altitude results in the optimum power/prop RPM/mixture combination. This enables pilots to realize fuel economy that would only have been dreamed of previously.
What is the function of EEC in aircraft?
The primary function of the EEC is fuel flow regulation and thrust management for optimization of flight performance at all times while protecting the engine against hazards.
What is Ng in aviation?
Ng: Gas generator rotation speed indication. Ng is an indication of the power output of the engine. The pilots and technicians reference the Ng speed to determine the engine power setting.
What is EEC system?
The EEC system is a method of controlling HC emissions by collecting fuel vapours from the fuel tank and carburettor fuel bowl vents, and directing them into an engine intake manifold. A typical evaporative emission control system is illustrated in Fig. 17.19.
What is fly by wire system in aircraft?
Fly-by-wire (FBW) systems are semi-automatic, computer-regulated aircraft flight control systems that replace mechanical flight controls with an electronic interface. Their “hands on” design gives pilots a direct, tactile feel for how the aircraft is handling aerodynamic forces as they fly.
Is the pt-6c engine available with FADEC?
The PT-6C engine is available with FADEC but appears to be more for rotorcraft. That being said its fundamentally a similar engine and the systems could be migrated to the common PT-6A. This is somewhat of an opinion based question depending on what you personally feel is necessary.
What is the cost of FADEC engine control?
The cost of FADEC is putting the engine control in the hands of a computer, which many are slowly becoming comfortable with. One thing to consider on smaller planes like the M600 is backup power systems.
What kind of engine is a PT6A engine?
The PT6A is a two-shaft engine with a multi-stage compressor driven by a single-stage compressor turbine and an independent shaft coupling the power turbine to the propeller through an epicyclic concentric reduction gearbox.
