201
What happens if both channels of the FADEC fail?
The engine fails
202
What controls the engines FADEC?
Permanent Magnetic Alternator – Above 50% N2
203
Normal start sequence:
N2 7% - Ignition, N2 20% - Fuel flow, N2 50% - Starter cutoff
204
What does the Starting system consist of?
Air Turbine Starter and Starter Control Valve
