Q

WHAT DOES THE FADEC DO?

Study These Flashcards
A
  • Automatic engine starting, preventing T4 exceedences
  • Proportional power turbine speed control with rotor noise reduction feature
  • Protection against engine surge and flame out
  • Bleed valve monitoring
  • Protection against NG and T4 overlimits
  • Engine Power Check (EPC)
  • NG and NF cycle counting
22
Q

HOW IS FUEL FLOW DETERMINED AND ADJUSTED?

23
Q

WHAT DOES THE DUAL STAGE STEPPED MOTOR DO?

Study These Flashcards
A

Provides fuel flow modulation by driving a metering valve in the engine’s ‘hydro-mechanical unit’

24
Q

HOW IS THE FADEC SUPPLIED POWER?

Study These Flashcards
A

2 channel gas generator driven independent alternator

25
FADEC SYSTEM FAILURES 3 LEVELS
*LEVEL 1* - **FLASHING YELLOW GOV LIGHT** Reset FADEC if before start In flight, continue to nearest maintenance center Applicable maintenance before next flight *LEVEL 2* - **SOLID YELLOW GOV LIGHT** Avoid operating at engine or torque limits, cautious flight **LAND AS SOON AS PRACTICAL** **DO NOT START ENGINE** * Applicable maintenance before next flight* * LEVEL 3* - **RED GOV LIGHT** (Total FADEC failure, metering valve frozen. EBCAU has taken over During start: **IMMEDIATELY SHUT DOWN** Avoid operating at engine or torque limits, *cautious flight* **LAND AS SOON AS PRACTICAL**
26
DESCRIBE THE 3 ANCILLARY SYSTEMS (PCB's under the rear right passenger seat)
PCB1 - Fire warning lights, Aural NR warning horns, Gong PCB2 - ENG chip, MGP chip, TGB chip caution lights, NR/NF signals, BATT TEMP warning light and processes VEMD electrical supply PCB3 - EBCAU backup unit
27
WHAT IS THE NAME OF THE SHROUDED TAIL ROTOR SYSTEM?
FENESTRON
28
HOW MANY BLADES MAKE UP THE FENESTRON?
10
29
WHAT INDICATION WILL A PILOT HAVE OF THE LANDING OR TAXI LIGHT ARE ON?
30
WILL THE AIRCRAFT START WITH THE ROTOR BRAKE OUT OF THE LOCKED POSITION?
NO
31
IS THE OVERHEAD FUEL CUT-OFF LEVER SAFETEY WIRED?
No, a plastic cover protects it
32
HOW MANY HYDRAULIC PUMPS?
2 ## Footnote Left hand gear driven for upper portion of servos Right hand belt driven for lower portion of servos
33
DO THE HYDRAULIC PUMPS USE SEPARATE RESERVOIRS?
YES
34
WHAT IS THE PURPOSE OF THE ROTARY DISTRIBUTION VALVE?
If one of the systems fails, the two valves move as an independent unit and supply pressurized fluid and return
35
IN THE EVENT OF HYDRAULIC FAILURE HOW DO THE HYD ACCUMULATORS HELP?
There are NO accumulators
36
CAN HYDRAULICS BE LOCKED IN PLACE WHILE AT IDLE?
There is no isolation switch
37
WHAT DOES THE INST 1 SWITCH DO ON THE LIGHTING CONSOLE?
Instrument panel lighting control
38
WHAT DOES THE INST 2 SWITCH DO ON THE LIGHTING CONSOLE?
Console and overhead lighting panel
39
WHAT DOES THE DAY SETTING DO?
VEMD and CWP lights are set to normal brightness
40
WHAT DOES NIGHT 1 AND 2 SWITCH DO?
VEMD and CWP lights are dimmed accordingly #2 shuts off compass light
41
DIRECT BATTERY SUPPLIES POWER TO WHAT?
* Transponder * NR/NF instrument * Instrument lighting * Reading and dome lights * Emergency floatation gear
42
WHEN DOES GEN TAKE OVER POWER PRODUCTION
When it produces .5 volt above battery
43
FAN OPERATION TEMP
On at 77c Off at 68c
44
TR SHAFT SPEED

50
WHAT IS SO IMPORTANT ABOUT THE WINDOWS AND INSTALATION IN AN EC130?
THEY ARE STRUCTUAL. CRACK CAN COMPROMISE THE AIRCRAFT
51
WHY ARE THE MAIN WINDOWS GLUED AND TAPED IN, BUT THE CHIN (LOWER) WINDOW IS BOLTED IN?
LOWER WINDOW MAY BE REMOVED EASILY FOR MX TO ACCESS FRONT EVAPORATOR IN THE B4
52
BEFORE ENGINE START, WHEN THE INDEPENDANT ALTERNATOR IS OFFLINE, HOW DOES THE FADEC RECIEVE AC CURRENT FOR START?
FROM THE STATIC INVERTER IN THE MASTER ELECTRICAL BOX UNDER THE REAR CARGO COMPARTMENT
