a 4 Engine-Driven pump low pressure. .
Note: With RAT extended, the green system is recovered. This permits to recover the flap
extensions.
However, green pressure will be lost when the speed will drop below 140 kt.
At the time, the red warning "G + Y SYS LO PR" will be triggered again.
With RAT extended, the fuel consumption is approximately increased by 1 %.
