Definition     a) Environmental   b) Pressurization   c) Emer press   d) Baggage heat Term       What systems are on the right knob? (air conditioning) Definition     a) Anti-ice   b) Environment   c) Pressurization   d) Service air Term       What system is not on the right knob? Definition           Baggage heat Term       How do you get incoming air in emer? Definition           Mass flow fail open Term       What do you use to get outgoing air in emer? Definition           In manual mode, using the cherry picker Term       What is the NACA scoop by the ACM exhaust? Definition           Keeps tailcone pressurized Term       How do you get hot air in the cabin? Definition         Mix recycled warm air over cold air from ACM Term       What valves control the air going to the ACM? Definition         Left and Right mass flow valves   APU BCV Term       How is cabin temperature controlled? Definition         Main DC in auto   Emer in manual Term       How long does the TCV go from cold to hot? Definition           10 seconds Term       Is it allowed to set HP with the engine bleed knob to heat the cabin below FL 370? Definition         Yes you can, if fuel consumption allow Term       What valves does the temperature select move? Definition           TCV's Term       Why is the APU needs to be off to do the bleed air test? Definition         ITT would not decrease   Engine would not have to "work" Term       Bleed air test: What happens when you turn the left engine bleed air knob? Definition         a) Shutoff Left bleed air valve   b) Left ITT decrease Term       Bleed air test: what happens when you turn the right engine bleed air knob to the off position? Definition                            a) Shut off the right bleed air valve   b) Right ITT decrease Term       Bleed air test: What happens when you turn the press source knob off? Definition       a) Both mass flow valve close (less demand on both engines)   b) Both ITT decrease Term       Bleed air test: what happens   when you turn the press source knob to emer? Definition       a) Emer press valve opens   b) Left mass flow remains closed   c) Left ITT decrease Term     Bleed air test: what happens when you turn the press source knob to the left?
