FADEC Engine Protections
The FADEC provides protections against:
-
Ng exceedance and underspeed during engine operation by modulating the
fuel flow,
-
TRQ exceedance during engine operation by reducing the fuel flow and, if
necessary, increasing Np to 2,000 RPM,
-
Np exceedance during engine operation by reducing the fuel flow and, if
necessary, by feathering the propeller,
-
uncommanded propeller reverse in flight, by feathering the propeller,
