Off - sign is off
On - sign is on
Auto - on or off depending upon landing gear or flap position

9

When do no smoking and seat belt signs automatically come on regardless of respective switch positions?

Anytime passenger oxygen is deployed

10

What does the Light Override (LT OVRD) switch do?

Max brightness for the five main cockpit light areas

11

What does the overhead panel Indicator Lights (IND LTS) switch do?

Sets all illuminated annunciator lights to either full brightness (BRT) or low brightness (DIM)

12

What does the overhead panel Indicator Lights (IND LTS) TEST switch do (3)?

1. Initiates the indicator lights test at the set brightness level
2. Tests the ADI and HSI displays if the aircraft is on the ground
3. Illuminates the IRS data display characters

13

What light switch controls the magnetic compass brightness?

Left panel light control on left glareshield

14

Exterior position lights are? (3)

Red
Green
White

15

Where are the anti-col white lights?

Wing tip

16

When does the nose landing gear light not illuminate? (2)

When either the switch is off with the nose gear locked down, or if the switch is on and the nose gear is not locked down

17

When does the taxi light not illuminate?

When the nose gear is not down and locked

18

Three positions and description of the Emergency (EMER) exit lights switch?

- Off - Lights will not work if aircraft electrical power is either selected off or fails
- Auto - Lights will turn on if aircraft electrical power (DC) is either selected off or fails
- On - all emergency lights illuminate

19

What does ENTRY DOORS or EMER DOORS light mean?

An Entry door or Emergency door is not closed, latched and locked.

20

What does the CARGO DOORS light mean?

the forward or aft cargo door is not closed, latched and locked

21

What does the ACCESS DOORS light mean?

the forward equipment bay or electrical equipment compartment door is not closed latched and locked

22

When the passenger entry door is armed what happens when door is opened from the inside and from the outside?

Inside - door is powered open and the slide deploys
Outside - door opens but the slide does not deploy

23

What happens when push PASS OXY switch? What does ON light mean?

- Switch on - passenger cabin masks deploy
- On light - passenger oxy system is operating and the masks have dropped

24

Oxy Mask difference between 100 percent and Normal?

100 percent = 100 percent oxygen
Normal = air/oxygen mixture on demand at a ration based on cabin altitude

25

Emergency position of Oxy mask does what? Caution?

Supplies 100% oxygen under positive pressure at all altitudes (to protect against smoke and harmful vapours)
Caution as it depletes oxygen at a higher rate than normal mode and only use as required (comms may be harder too)

26

Smoke vent valve selector does what on mask?

Opens the vent valve allowing oxygen to flow to the smoke goggles

27

If normal electrical power is lost where do some essential cockpit lighting get their power from?

Automatically switched to the Standby AC Bus

28

When does the Indicator Light brightness get automatically overridden from DIM? (3)

1. Ambient flight deck light level increases to a preset crossover level
2. Loss of equipment cooling air flow as detected in the flight deck or in the FWD E/E bay
3. Equipment cooling air overheat is detected in the flight deck or in the FWD E/E compartment or at the cooling air supply source

29

Four times when seat belt signs come on when switch is in AUTO?

1. landing gear not up and locked, or
2. Flap lever not up, or
3. Cabin altitude above 10K, or
4. Pax oxy on

30

Three times NO SMOKING signs on when in AUTO

1. landing gear not up and locked, or,
2. Cabin altitude above 10K, or
3. Pax oxy on

31

What other switch (non-flight deck) can turn the emergency lighting on?

The flight attendants emergency lights switch

1. Do not operate greater than 40kts
2. Do not leave open with gusts more than 65kts

38

What does the break away feature on the cockpit door do?
