Airplane General Flashcards
What will cause the emergency exit lights to illuminate when armed?
(2)
Loss of AC power OR loss of DC Bus 1
SH 1.040 PG 45
Are there any limitations on an aircraft with retractable landing lights?
There is no speed restriction for operation of the lights.
SH 1.030 PG 30
What do each of the exterior lights illuminate?
Where are they and what do they do
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
SH 1.030 pg 33
When is 100% supplied to the flight deck oxygen masks?
Any time the switch is in position
NORM = 100% on demand
EMERGENCY = 100% with positive pressure (continuous flow)
SH 1.040 PG 11
*What triggers the MASTER CAUTION (amber) lights? What triggers the associated System
Annunciator lights?
MASTER CAUTION = caution outside pilots’ normal field of view
SH 1.030 PG 3
What causes the MASTER CAUTION and System Annunciators to
Extinguish?
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)
SH 1.030 PG 4
What is the difference between single and dual channel systems? How are system
indications different for single channel vs dual channel systems?
Dual channel = redundancy within system
Single 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!
SH 1.030 PG 4-5
What is the light logic of the aircraft?
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)
SH 1.030 pg 1
How are the 6 Flight Deck windows different from each other? Which ones open?
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.
See Figure 5 in the SH 1.030 PG 11
What is the Flight Deck Access System (FDAS), and how does it operate?
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
Flight deck door lock panel annunciators:
LOCK FAIL = lock selector in AUTO and lock has failed or FDAS switch is OFF
AUTO UNLK = correct access code entered, flashes and aural chime alert
After correct code entered into keypad, 60 second timer and:
Two chimes each 20 seconds and steady AUTO UNLK (40 sec)
Last 20 seconds are continuous chime and flashing AUTO UNLK
Flight crew can select DENY = locks out the keypad for 5 minutes
Selector spring loaded to AUTO. UNLK will unlock door as long as selector held in
position.
SH 1.030 PG 17-18
How is the Passenger Oxygen system actuated and how long does it supply oxygen?
Automatically - cabin pressure of 14,000ft
Manually - PASS OXYGEN switch ON
12 minute supply of oxygen
SH 1.040 pg 23
Which systems can pressurize the Potable Water System and what conditions must be met
for it to operate?
(3)
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
SH 1.030 PG 40
Do the FAs have control of the Emergency lights? What priority do they have, if any?
Yes, they can override cockpit switch
Works even if flight deck switch is OFF or failure of automatic control with loss of
power
SH 1.040 PG 46
Where are the water fire extinguishers and halon fire extinguishers?
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
SH 1.040 pg 28 and SH 1.050 pg 86
What do the different fire extinguishers contain, and what kind of fires are they effective on?
Water fire extinguisher:
- Contains water mixed with antifreeze
- Effective on class A fires only (wood, fabric, paper, etc)
Halon fire extinguisher: -effective on all types of fires - but primarily on electrical, fuel, and grease fires - Contains 2.5 lbs of Halon at 100psi nitrogen charge
SH 1.040 pg 28
