How does an EEC work?
The EEC is an electronic control, mounted on the engine or engine fan case, drawing power from an engine alternator to receive data from sensors measuring pilot commands and monitoring flight and engine conditions such as throttle position, fuel flow, temperature, vibration, and pressure.
What is electronic engine control systems?
An electronic engine control system is an assembly of electronic and electromechanical components that continuously varies the fuel and spark settings in order to satisfy government exhaust emission and fuel economy regulations.
What is FADEC and ECU how it can help the pilot?
FADEC is a system consisting of a digital computer, called an electronic engine controller (EEC) or engine control unit (ECU), and its related accessories that control all aspects of aircraft engine performance.
How does the EEC control or to maintain the thrust power of the engine?
The EEC computer uses data it receives from many engine sensors and airplane systems to control the engine operation. It receives electronic signals from the flight deck to set engine power or thrust.
What are the two modes of operation of EEC?
The EEC can control the engine thrust in two modes, which can be selected by use of a mode selection switch. In the normal mode, engine thrust is set with EPR; in the alternate mode, thrust is set by N1.
What is the main function of ECU?
An engine control unit (ECU), also commonly called an engine control module (ECM), is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance.
Why do we need electronic engine control?
Electronic control allows you to control the injection of fuel more accurately to optimise the power delivery and fuel consumption compared to mechanically controlled engines.
How is FADEC powered?
The FADEC system is self-powered by a dedicated permanent magnet alter- nator when N2 is above 15%, and is powered by the aircraft for starting, as a backup and for testing with engine not running.
Which controls the power supply to the APU EEC unit?
Power for the EEC comes from the aircraft electrical system or the permanent magnet alternator (PMA). When the engine is running, the PMA supplies power to the EEC directly. The EEC is a two channel computer that controls every aspect of engine operation.
What is the difference between EEC and EU?
The European Economic Community (EEC) was a regional organization that aimed to bring about economic integration among its member states. It was created by the Treaty of Rome of 1957. Upon the formation of the European Union in 1993, the EEC was incorporated into the EU and renamed the European Community (EC).
Where is the ECU located?
On most models the ECU is located beneath the wipers behind the plastic trim.
What is MFD in aviation?
Multi-Function Display (MFD): A small screen (CRT or LCD) in an aircraft that can be used to display information to the pilot in numerous configurable ways. Often an MFD will be used in concert with a Primary Flight Display.
Does the EEC still exist?
Upon the formation of the European Union in 1993, the EEC was incorporated into the EU and renamed the European Community (EC). In 2009, the EC formally ceased to exist and its institutions were directly absorbed by the EU. This made the Union the formal successor institution of the Community.
Is the UK still part of the EEC?
The United Kingdom (along with the British Overseas Territory of Gibraltar) was a member state of the European Union (EU) and of its predecessor the European Communities (EC) – principally the European Economic Community (EEC) from 1 January 1973 until 31 January 2020.
How does a ECU work?
Fundamentally, the engine ECU controls the injection of the fuel and, in petrol engines, the timing of the spark to ignite it. It determines the position of the engine’s internals using a Crankshaft Position Sensor so that the injectors and ignition system are activated at precisely the correct time.
How many controls are there in a helicopter?
There are 4 pilot-operated controls in a helicopter. The Throttle is used to control the power of the engine. The Pedals turn the helicopter around its mast in a hover. The Collective is used to climb or descend and the Cyclic is used to control the direction the helicopter travels.
What are the collective and cyclic used for in helicopters?
The Collective is used to climb or descend and the Cyclic is used to control the direction the helicopter travels. Now you have the very basic explanation let’s look at each one in detail so you have a full understanding of how they all work to make one of these things fly!
What is the function of the throttle on a helicopter?
The Throttle is used to control the power of the engine. The Pedals turn the helicopter around its mast in a hover. The Collective is used to climb or descend and the Cyclic is used to control the direction the helicopter travels.
How do helicopter pedals work?
The Pedals turn the helicopter around its mast in a hover. The Collective is used to climb or descend and the Cyclic is used to control the direction the helicopter travels. Now you have the very basic explanation let’s look at each one in detail so you have a full understanding of how they all work to make one of these things fly!
