FADEC (Full Authority Digital Engine Controls)

There are revolutionized in the Aviation industry especially in aviation structural mechanic and Modern Turbofan Engine Operations in terms of Autonomy, Reliability & Efficiency through micro-management?
Back in the 1970s, Baby steps were taken & Digital Engine Controls were introduced with the 'DEEC' for the PW JT9D engines.
By 1980s, demand surged, 'FADEC' had to evolve to cater to more capabilities for the engine.
Several computers or mainframe combine to form the control system, with the FADEC acting as the ‘brain’ of the engine.
FADEC tells you, No direct human control over the engine or manual control mode.
FADEC includes engine sensors, control logics & laws, the fuel metering device & interfaces with the aircraft computers.
FADEC is autonomous, self-monitoring, self-operating & redundant (less likely to fail). If the FADEC fails, the engine fails.

Micromanagement of FADEC :

Controls the gtr engine 'thrust target' to manage the aircraft speed, acceleration & deceleration.
Monitors the Engine Health & System behavior.
Optimisation of fuel consumption & emission levels.
Controls actuation & power supply of the thrust reverser system.
Detects, analyses & announces failures, as well as protects from malfunctions.
