IN CRUISE TASK SHARING
In cruise, the task sharing is let to crewappreciation.

PFPF PNFPNFSYSTEM DISPLAY REVIEW
Oil pressure and temperature
A slight decrease in quantity is normalFluid contraction during cold soak can be expectedGreen system is lower than on ground,following landing gear retraction
BLEED parameters
Duct temperature, compared with zone temperatureAvoid large differences for passenger comfort
