Systems Exam Flashcards
A temperature of each aircraft zone is optimized by means of a ???
A TRIM AIR valve
Under what conditions should the pack flow controller be set to LOW?
With a low passenger load to reduce bleed air demand and improve fuel efficiency
The PACK FLOW controller is set to NORM and yet the ECAM display shows PACK FLOW to be high. How is this possible?
HI flow is automatically selected regardless of PACK FLOW selector position because air is only being supplied by the APU
The safety valve protects the aircraft against?

In Normal Law, is there a maximum pitch attitude?
(“A”) (yellow line on PFD)
Yes, indicated by the green dashes
