Airplane General

Question 1

What will cause the emergency exit lights to illuminate when armed?

Answer 1

Loss of AC power OR loss of DC Bus 1

Question 2

Are there any limitations on an aircraft with retractable landing lights?

Answer 2

There is no speed restriction for operation of the lights.

Question 3

What do each of the exterior lights illuminate? Where are they and what do they do

Answer 3

Landing Lights (wing root) - shines straight ahead
Taxi - (nose or wing root) - shines straight ahead
Runway Turnoff - shine out at 45 degree angle (not forward facing)
Logo (on the tail) - Chester
Strobe (wings and tail) - strobe lights
Anti-collision (belly and roof) - red beacon
Position (wingtips) - nav lights
Wing lights (fuselage) - illuminates leading edge of the wing for inspection
Wheel well (nose and main wheel wells) - illuminates wheel wells

Question 4

When is 100% supplied to the flight deck oxygen masks?

Answer 4

Any time the switch is in position
NORM = 100% on demand
EMERGENCY = 100% with positive pressure (continuous flow)

Question 5

*What triggers the MASTER CAUTION (amber) lights? What triggers the associated System Annunciator lights?

Answer 5

when any caution occurs outside the normal field of vision of the Flight Crew. The lights remain illuminated as long as the caution condition exists, or until the crew resets the Master Caution System

Question 6

What causes the MASTER CAUTION and System Annunciators to Extinguish?

Answer 6

A Master Caution Reset (pushing the light)
A Master Caution Reset is accomplished by pushing either MASTER CAUTION light. This resets the Master Caution System and results in
- Both MASTER CAUTION lights extinguishing
- All system annunciator lights extinguishing, and
- The Master Caution System is reset for further cautions
The caution light on the overhead panel remains illuminated until the caution condition no longer exists (except for single / simple faults)

Question 7

What is the difference between single and dual channel systems? How are system indications different for single channel vs dual channel systems?

Answer 7

Dual channel = redundancy within systemSingle channel = no redundancy within system
Dual channel system loses a single channel? No caution light, only found by recall and is stored in the Master Caution system - it won’t tell you!Single channel system fails? You will have an annunciator - it will tell you!

Question 8

What is the light logic of the aircraft?

Answer 8

RED = Immediate
AMBER = Timely
Dim blue = Status light (correct position)
Bright blue = Status light (in transition or disagreement)
Dark aircraft concept - normal conditions in flight = no lights (mostly)

Question 9

How are the 6 Flight Deck windows different from each other? Which ones open?

Answer 9

On both sides, #1 and #2 are heated. #2 opens. #3 not heated and does not open. FO side #2 window opens from the outside.

Question 10

What is the Flight Deck Access System (FDAS), and how does it operate?

Answer 10

Provides flight crew with full control of the flight deck door during normal operations.

• Automatically locks under DC power
• Manual control with deadbolt and FDAS switch
• Emergency code for access in case of pilot incapacitation

Question 11

How is the Passenger Oxygen system actuated and how long does it supply oxygen?

Answer 11

Automatically - cabin pressure of 14,000ft Manually - PASS OXYGEN switch ON 12 minute supply of oxygen

Question 12

Which systems can pressurize the Potable Water System and what conditions must be met for it to operate?

Answer 12

Bleed air from engines or APU
OR if insufficient bleed air, an AC electric compressor IF:
- pressure in the water tank is less than 30 psig (pressure limit switch is closed)
- water service panel door is closed (compressor cut-out switch is closed)
- CAB/UTIL switch ON

Question 13

Do the FAs have control of the Emergency lights? What priority do they have, if any?

Answer 13

Yes, they can override cockpit switch

Works even if flight deck switch is OFF or failure of automatic control with loss of power

Question 14

Where are the water fire extinguishers and halon fire extinguishers? *

Answer 14

Water fire extinguishers - Passenger cabin only
Halon fire extinguishers:
- 1 behind FO seat mounted to CB panel
- 2 in pax cabin (1 forward, 1 aft, see fig 74) *2 in pax cabin required for
dispatch

Question 15

*What do they contain, and what kind of fires are they effective on?

Answer 15

Water fire extinguisher
- Contains water mixed with antifreeze
- Effective on class A fires only (wood, fabric, paper, etc)
Halon fire extinguisher
- Contains 2.5 lbs of Halon at 100psi nitrogen charge
- can be used for all types of fires, but primarily class A+B electrical, fuel, and grease fires

Question 16

How are the fire extinguishers pressurized, and how can you tell they are serviceable?

Answer 16

Water - pressurized by Co2 cartridge, trigger is safety wired
Halon - pressurized by nitrogen, gauge in green and pin in with red tie indicates it’s serviceable

Question 17

What causes the overwing emergency exits to lock?

Answer 17

The overwing exit locks engage when:
- Minimum 3 of 4 entry/service doors closed AND
- Either engine running AND
- Airborne OR thrust levers advanced
Any of the above conditions not met or loss of DC power? Unlocked

Question 18

What do the Emergency Exit Lights illuminate, and how are they powered? Activated?

Answer 18

Illuminate approved emergency exit routes (inside cabin) and evacuation areas (exterior)
- Powered by battery packs charged by AC power and the EMR EXIT
Lights switch in OFF or Armed
- Activated manually by switch ON or automatically with loss of AC power or power to DC Bus 1
