Q

CLIMB mode

*Automatic pressurization mode

A

Automatically controls cabin climb rate according to theoretical schedule of cabin altitude versus aircraft altitude

Also takes into account the rate of climb and landing field elevation.

Typical climb rates are 300-500 fpm with max rate of 635 fpm at lighter weight and best climb

*Above 25000, high rates of climb (>6000 fpm) may cause cabin rate of climb to exceed 635 fpm max and should be avoided for auto overpress protection and cabin comfort

Q

When will HYD SHUTOFF VLV close

(2)

A

Fire switch depressed

or

Shut off valve closed

Fluid temp above 135°C (skydrol boiling point)

23
Q

What are the HYD DCMP power sources?

A

Left DCMP = RIGHT MAIN BUS

Right DCMP = LEFT ESSENTIAL BUS

24
Q

What is the primary purpose of the PTU?

When does it run?

A

To aid in gear retraction

Comes on when gear is being retracted and

Left EDP pressure is low

25
What does the AUX HYD system power?
Assists the lower rudder PCU
26
How are gear up locks released?
When extension commanded, gear initially over stows the gear, releasing the mechanical up locks. This allows mechanical up lock hook to be retracted for extension. Mechanical Right hydraulic gear asssit
27
The GEN overload message comes on at what load?
501 AMPS
28
What inputs arm the GROUND SPOILERS in AUTO mode (4)
Inputs come from : RADALT Wheel Speed WOW TLA
29
When do GROUND SPOILERS extend in MANUAL ARM
Thrust Levers Idle and WOW only \*Manual Arm mode does not provide additional input protection available in AUTO.
30
ALTN FLAPS
When ALTN FLAPS selected: Left HYD system pressure powers flaps. Flow restricted (to prioritize gear actuation) Takes over 1 min to extend flaps from 0°-20° Normal flaps (R) HYD system = O°-30° is 20 seconds
31
CONFIGURATION TRIM
Stab trim automatically adjusts when gear and flaps are extended to smooth out oscillations
32

38
RA INHIBIT Parameters (3)
1. Descending below 900' AGL, or climbing below 1100' AGL All RA's inhibited (TA ONLY) and TA AURAL INHIBITED 2. Descending below 1000' AGL or below 1200' AGL and climbing DESCEND RA inhibited 3. Below 1450' AGL INCREASE DESCENT inhibited
39
DESCENT MODE \*Automatic pressurization mode
Aircraft descends at preset rate Varies based on aircraft rate of descent and time remaining to land. 2000 fpm aircraft rate yields 300 fpm cabin rate 5000 fpm and greater descent rate yields cabin descent of 750 fpm Decent continues to 300' below landing field elevation.

GS = BC Approach or GS inop Flaps = Landing less than flaps 30 Airport not in database
49
What is lost with Secondary Trim use?
Autopilot Mach Trim Configuration Trim Memory Aid: MAC (Mach)
50
How are electrical buses powered?
Battery always powers respective Batt Bus Batt ON powers respective Essential Bus Generators power respective Main Bus Aux buses powered by generators thru respective Main bus
51
With a single generator in flight, what buses are powered? With single generator on the ground, what buses are powered?
In flight: Operable: Essential, Main, Battery. Single gen sheds Aux buses. On Ground: Single Gen everything is still powered
52
With one engine-driven gen in flight and APU operating: What does APU power?
APU gen will power the Main Bus on the side with the lost gen while in flight with one engine-driven generator on line.
53
In flight, with no engine-driven gens and only APU: What is powered?
In flight, APU operating with no engine-driven gens: APU powers (R) Main , bus ties contactor closes (BTC) and powers (L) Main.

What happens in flight with no generators? (No APU or Engine Driven Gens online)
With no generators on line, each battery powers respective Batt and Essential busses, and BTC closes. Battery duration is 1 hour in this situation
