CBT 1-4 Flashcards
Emergency lights armed
ARMED – If the airplane looses normal power, the emergency lights will automatically turn on.
The emergency lights have a dedicated battery that provides 10 minutes of use.
Egpws
The EGPWS will also warn the pilot for:
• • • • Excessive sink rate on approach
Altitude loss after takeoff
Glideslope deviations on approach (too low)
Excessive bank angle (more than 40 degrees)
Green dots:
• Terrain 500-2000 ft below airplane
Yellow dots:
• Terrain 500 ft below to 2000 ft above airplane altitude
Red dots: • Terrain more than 2000 ft above airplane
RA condition
The other airplane is approximately 20-30 seconds from the TCAS collision area
Traffic advisory conditions
The other airplane is approximately 35-45 seconds from the TCAS collision area
• “TRAFFIC, TRAFFIC” aural alert is played •
Traffic turns amber
Normal traffic in cyan
Takeoff config warning / OK
When thrust is applied for takeoff, the T/O Config checks: •
• • • Parking brake (off)
Pitch trim (in green range)
Spoilers (closed)
Flaps (flap position matches MCDU takeoff flap setting)
If any items is not in the takeoff position, a triple chime and aural is played. e.g. “Ding Ding Ding, NO TAKEOFF, FLAPS”
Waste system
When the tank reaches 75% capacity, the “Service Tank” indication illuminates. When the tank is full, the “TANK FULL” illuminates and toilets are disabled.
FFOD - FA discovers that the Water System
fault light is ON.
The crew should: • Verify that the potable water was drained and purged when RON temperature was 0⁰C or colder.
• report the mechanical irregularity
Potable water (70 liters) dumping
Pressing the DUMP button dumps potable water (only available in flight, takes about 10 minutes). Dump button not available on all aircraft.
Must be drained and purged when RON (Remain Overnight) temperature was 0⁰C or colder. temperatures.

Attcs
Engine indicating crew alert system
Enhanced ground proximity warning system
(Automatic Takeoff Thrust Control System
ATTCS
ATTCS (Automatic Takeoff Thrust Control System) is a FADEC feature that will automatically increase thrust during a takeoff or go-around when thrust levers are in TOGA and:
• An engine failure is detected,
or • N1 difference between engines of 15% or more,
or • Windshear is detected
Limitation: ATTCS must be ON for takeoff
The max ITT for engine start is
815°C (the red tick mark).
Limitation oil during start.
Minimum oil pressure after engine start: green. 25 psi.
During engine start, the oil pressure must be greater than zero within 10 seconds. If not, the start is aborted.
Engine vibration abnormal indication
Mod or severe icing can cause
if vibrations are abnormal (amber indication). Consider aborting takeoff
Crossbleed starts psi req.
40 -45 psi.
Try to limit thrust to 40%N1.as much as possible on ground
Starter limits
Start attempt 1 & 2: 90 seconds ON, 10 seconds off.
Start attempts 3-5: 90 seconds ON, 5 minutes OFF.
Increase start attempt time to 120 seconds if in flight.
IGNITION Selector Knobs Options:
OFF: Deactivates ignition and inhibits fuel flow on the ground. The FADEC ignores OFF in flight.
• AUTO: FADEC turns the ignition ON when: • Engine Start Attempt (with at least 7% N2), (one igniter)
• Automatic re-light (both igniters)
• OVRD: Enables FADEC to continuously activate both igniters
Thrust rev indication
Amber when commanded open. Green when full open between N1 and ITT
Before each flight oil must indicate
Green. Not amber
When does the sopm say to start the Apu
Approximately 10 minutes prior to departure, start the APU
What happens if a TRU fails
DC Busses will be powered will by the remaining TRUs (as long as the DC BUS TIES toggle switch is selected to AUTO).
Main purpose of AC standby bus
powered from a DC Bus through an inverter. It is powered as soon as the batteries (DC) are turned ON.
It powers exciters for the engine
Allows for engine start with no AC power
AC Ess powers what
AC Fuel pump 2A
ACMP 3A
Flap ch1
Slat ch2
Battery operations limits
Upon establishing battery power, the battery voltage is checked. The minimum voltage for normal operation is 22.5V.
Rated 24V
28 when charging
What happens when DISC is selected on the IDG switch?
What does an amber light mean next to the switch?
DISC: Mechanically disconnect the IDG (must be held in this position for at least one second) and then reset by maintenance.
The amber light near the knob turns on if the system senses low IDG oil pressure or high IDG oil temperature. The associated IDG OIL caution message is displayed on the EICAS.
Normal position of APU switch light.
PUSH IN: Automatically controls the APU generator (turned on when the APU is started, off when the APU is shutdown).
DC BUS TIE TOGGLE SWITCH Options:
- AUTO: Allows automatic operation of the DC Bus Ties
* OFF: Opens both essential tie contactors (ETCs) and a DC tie contactor (DCTC).
BATTERY 2 SELECTOR KNOB
• AUTO: The battery automatically powers either DC Bus 2 OR the APU Start Bus (during the APU start). Also powers the Hot Battery Bus 2.
Hot battery bus powers what?
Pressure refuel panel.
Engine fire fighting
What is the AMS and it’s functions
The AMS is a pneumatic system that provides power to the following: *ECS (Environmental Control System) • Engine and wing anti-ice • Water pressurization • Engine starter
Ram air purpose and conditions when opened
Ram Air Provides emergency ventilation in case of: •
Pack shutdown • Smoke removal
The Ram Air valves are automatically commanded OPEN if both packs are OFF below 25,000 ft.
Also, includes a check valve that only allows ram air into the cabin when: • Ram air pressure > cabin pressure
Single pack limits
A single PACK is capable of keeping adequate cabin/cargo hold pressurization and temperature up to 31,000 ft.
