PC - Systems

Question 1

Additonal function of BLEED on MAX vs NG

Answer 1

Incorrect bleed config 45 sec after flap retraction in the air - either bleed switched on extinguishes both lights

Question 2

Both PACK lights illuminated on MAX

Answer 2

Incorrect pack config 45 sec after flap retraction in the air - either pack switched on extinguishes both lights

Question 3

MAX COWL VALVE and ENG ANTI-ICE lights

Answer 3

COWL VALVE: momentary-valve in transit. Steady-position disagree with related ENG ANTI-ICE switch

ENG ANTI-ICE: System inhibited due to system failure or core anti-ice valve fails closed

Question 4

Arming VNAV on ground criteria

Answer 4

Flight plan, PWB, FD’s on

Question 5

Alt Intervention in VNAV Cruise

Answer 5

If higher altitude in MCP than FMC then FMC cruise alt will be reset to MCP alt.

If lower alt in MCP but at or above any descent constraint it will initiate CRZ DES at 1000fpm to new CRZ alt and will recruise the vnav page if aircraft is more that 50nm from TD. — IF less than 50nm from TD, early descent mode is engaged.

If more than 50nm to TD with MCP alt set below descent constraint, descent at 1000fpm will engage till capturing descent path or MCP alt is captured

Question 6

TO/GA FD commands on takeoff

Answer 6

<60kts 10* nose down
>60kts 15* nose up
After takeoff 15* nose up till sufficient climb rate established then commands MCP+20

Question 7

TR Unit light

Answer 7

Any TR on the ground, or TR 1 or 2 and 3 in the air

Question 8

STBY power off light

Answer 8

Loss of power to: AC or DC stby bus or Batt bus

Question 9

IF all power is lost

Answer 9

Stby switch in auto: battery powers the AC stby bus via STATIC INVERTER. DC stby, battery, and hot battery and switched hot battery are powered directly by the battery.

Functionality retained on CA Inboard/outboard DU, Clocks, CA EFIS panel, Stby flight display, magnetic compass

Question 10

REVERSER LIMITED on MAX

Answer 10

on ground: fault
in air: fault, will not deploy or will be limited to idle

Question 11

Engine overheat/fire detection and supression powered by

Answer 11

Battery bus and hot battery bus respectively

Question 12

What will spoilers do if Speed Brake is in DOWN on landing

Answer 12

Auto speed brake system: when main wheels >60kts, both thrust levers idle, reversers are deployed

Question 13

White sharks tooth

Answer 13

Takeoff: V2+15
Landing: 700 vREF+15
800/MAX vREF+20

Question 14

IAS disagree

Answer 14

CA and FO differ by more than 5kts for more than 5sec

Question 15

EFC on hold page affects arrival fuel how

Answer 15

assumes departure from holding fix at EFC time

Question 16

FMC calculates available hold time how

Answer 16

destination to be reached with planned reserves entered on perf init page

Question 17

FUEL FLOW (MAX) indicate?

Answer 17

The flow rate exceeds for 5 continuous minutes

Question 18

MAX vs NG fuel alerts

Answer 18

FUEL DISAGREE - totalizer and FMC

USING RSV FUEL - FMC fuel predicted to be less than entered reserves

INSUFFICIENT FUEL - FMC fuel predicted to be less than 2000lb

Question 19

PWB MEL/CDL penalties

Answer 19

Remarks page, release received by pwb system and taken into account

Question 19

First indication of PSEU fault

Answer 19

30 sec after landing. Inhibited in flight

Question 20

Predictive windshear

Answer 20

begins scanning when TLA is T/O. aLERTS available 12 seconds after radar starts scanning. IF wxr is pushed on efis, alerts are enabled before takeoff below 1200ra

Question 21

GPWS windshear

Answer 21

enabled at rotation below 1500ra

Question 22

What provides the auto populated arrival fuel for pwb

Answer 22

dispatch release planned arrival fuel
