Flashcards in Ground Deck (51):
What screens populate during the safety power?
Captains MFD and EICAS
What if more than screens 2 and 3 populate during the safety power up
Only 2 and 3 should populate
After powering up the aircraft using the batteries you hear a warning horn after 5 minutes. For what reason?
Power up w/no (GPU/APU) AC power
Power is only available for 10 minutes while using the batteries alone.
A sustainable power source (APU/GPU) must be established durning the SafetyPower up checklist. Otherwise a warning horn will signal after 5min.
How many loops for fire detection?
Describe the cargo fire protection system.
- 3 (fwd) detectors
- 2 (aft) detectors
- 2 bottles - low and high rate
You have a "non annunciation" APU smoke/fire on the ground. How would you discharge the fire bottle? What would be different if it was annunciation?
- Press APU fire bottle discharge 1 time to arm, press again to discharge high rate
- annunciated, the APU would automatically shutdown and discharge fire bottle after 1 minute
Can we start the APU w/battery 1/2 differed or Inop?
Battery 1 must be operable.
APU, may be started w/battery 2 differed utilizing an external DC GPU
What is the power priority on the ERJ?
- Onside: IDG
- Inside: APU
- Outside: GPU
- Cross-side: opposite IDG
What are the 4 items on the AC Ess bus if the RAT deploys?
1. 1 slat channel
2. 1 flap channel (max flaps 3)
3. AC fuel pump 2 (set low 1 to x-feed)
4. Hyd sys 3
How are the slats/flaps actuated?
With a loss of High level functions what will be affected ... or with a loss of FCM what high level functions will be lost?
1. Stall protection / AOA limiting
2. Gain / thrust compensation
With the RAT deployed how many notches of flaps are we limited to?
What 3 things interrupt a electrical PBIT test? Hyd?
- AC power interruption
- FCMP switches cycled
- Hyd pump running
- flight control movement
What will interrupt a electrical/hydraulic PBIT test? How long does it?
AC Power interruption
Cycle Fcmp mode buttons
Hyd pump activation
Flight control movement
3min - electrical
90sec - hydraulic
On the ground, the ACMP 1 comes on when? In flight?
- flaps > 0'
- thrust set to T/O
- GS > 50kts
- EDP failed
- Flaps > 0'
Electric hydraulic pump 2 comes on when?
- eng 1 running and parking brake released
What must be done taxiing out on Eng 2?
QRH normal procedures
Turn pump 1 ON
What is the purpose of the PTU?
It works only when engine driven is not operating
- Assist in gear retraction in the event of (eng 2/EDP2) failure
- Assists in the loss of right engine (#2) failure
(V1 cut on T/O)
**Hyd reservoir 2 must be above 12%**
** you must have some Hyd fluid**
PTU backups the #2 Hyd system utilizing a separate Hyd pump and hyd fluid from the #1 system
What systems are utilized on Hyd 2?
1. nose wheel Steering
2. inboard aileron
3. inboard elevator
4. inboard brake
5. Onside Reverser 2
6. MultiFunctional Panel 5
7. Ground spoiler 1
In doubt: check hyd synoptic page on mfd
In "direct mode" what is the major concern?
No STALL protection
Loss of AOA limiting
May a PBIT test be interrupted? What if you receive an expired message?
if 50hr expiration time has not exceeded the flight may continue to T/O
If you receive an expired message simply re-run the test
Who does the walk around?
Either crew member may do, PIC is ultimately responsible
What does a "flight control no dispatch" message on EICAS mean?
- Return to gate
- contact MX
Who is generally responsible for inputting flight plan and performance info durning preflight?
PM cross references / confirms
What are the oxygen requirements pertaining to crew members allowed in the flight deck?
Green - 3 (CAPT, FO, observer)
Cyan- 2 ( Capt, FO)
Amber - no dispatch
APU is started when?
10 prior to pushback
What are the power and fuel sources for the APU?
- DC fuel pump on the ground, AC in flight
- Right fuel tank
What's the max tailwind?
Who calls "positive rate?"
What will happen if 1 thrust lever is actuated more than the other with AutoThrottles armed in flight?
Thrust levers may disagree up to 1/2 lever head before AutoThrottles will disengage
When do the auto throttles transfer from armed to engaged?
Thrust lever angle >50°
When does the white "HOLD" populate on the FMA?
- 60kts and above
- holds the trust setting
- solenoids for auto throttles de-energize
When does the "track" message populate on the FMA?
- 100 kts
- IRS takes a snapshot of the A/C track and fly's calculated path
What are the 2 AutoThrottle modes? What are the differences
- speed on thrust - will assign power given specific mode
- speed on elevator - only w/FLCH - predicates power based on pitch. (ALL or NO thrust)
When will the "down lock" release for the landing gear ever be actuated UP?
Emergency Performance relating to TERRAIN
Where do you pitch during an RA?
What are the indications of ICE accretion?
- stall prot
- ice condition
What does the Chevron next to a message on the EICAS mean?
- dealing with the chevroned message will likely fix separate EICAS messages listed below
What 3 things are checked by the PM during the "check thrust" call on the T/O roll?
- ATTCS green
- Fuel flow
What happens if the Captains ADS 1 fails? FO's?
- Reverts to (FO's) ADS2
- FO's reverts to (STBY) ADS3
What is the APU fuel flow?
DC pump --> AC pump --> Motive flow
What happens during an electrical emergency?
