Q

WHAT DOES THE FADEC DO?

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?

A

By the FADEC

23
Q

WHAT DOES THE DUAL STAGE STEPPED MOTOR DO?

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?

A

2 channel gas generator driven independent alternator

25
Q

FADEC SYSTEM FAILURES 3 LEVELS

A

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
Q

DESCRIBE THE 3 ANCILLARY SYSTEMS

(PCB’s under the rear right passenger seat)

A

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
Q

WHAT IS THE NAME OF THE SHROUDED TAIL ROTOR SYSTEM?

A

FENESTRON

28
Q

HOW MANY BLADES MAKE UP THE FENESTRON?

A

10

29
Q

WHAT INDICATION WILL A PILOT HAVE OF THE LANDING OR TAXI LIGHT ARE ON?

A
30
Q

WILL THE AIRCRAFT START WITH THE ROTOR BRAKE OUT OF THE LOCKED POSITION?

A

NO

31
Q

IS THE OVERHEAD FUEL CUT-OFF LEVER SAFETEY WIRED?

A

No, a plastic cover protects it

32
Q

HOW MANY HYDRAULIC PUMPS?

A

2

Left hand gear driven for upper portion of servos

Right hand belt driven for lower portion of servos

33
Q

DO THE HYDRAULIC PUMPS USE SEPARATE RESERVOIRS?

A

YES

34
Q

WHAT IS THE PURPOSE OF THE ROTARY DISTRIBUTION VALVE?

A

If one of the systems fails, the two valves move as an independent unit and supply pressurized fluid and return

35
Q

IN THE EVENT OF HYDRAULIC FAILURE HOW DO THE HYD ACCUMULATORS HELP?

A

There are NO accumulators

36
Q

CAN HYDRAULICS BE LOCKED IN PLACE WHILE AT IDLE?

A

There is no isolation switch

37
Q

WHAT DOES THE INST 1 SWITCH DO ON THE LIGHTING CONSOLE?

A

Instrument panel lighting control

38
Q

WHAT DOES THE INST 2 SWITCH DO ON THE LIGHTING CONSOLE?

A

Console and overhead lighting panel

39
Q

WHAT DOES THE DAY SETTING DO?

A

VEMD and CWP lights are set to normal brightness

40
Q

WHAT DOES NIGHT 1 AND 2 SWITCH DO?

A

2 shuts off compass light

VEMD and CWP lights are dimmed accordingly

41
Q

DIRECT BATTERY SUPPLIES POWER TO WHAT?

A
  • Transponder
  • NR/NF instrument
  • Instrument lighting
  • Reading and dome lights
  • Emergency floatation gear

A

It is FAA approved

47
Q

Which sections of the RFM are FAA approved, or complimentary?

A

Sec 1-5 and 9 are FAA approved

Sec 6,7,8,10,11 Complimentary

48

A

SBT (Service Bulletin) Due to an incident or event

SLT (Service Letter) Information

50
Q

WHAT IS SO IMPORTANT ABOUT THE WINDOWS AND INSTALATION IN AN EC130?

A

THEY ARE STRUCTUAL. CRACK CAN COMPROMISE THE AIRCRAFT

51
Q

WHY ARE THE MAIN WINDOWS GLUED AND TAPED IN, BUT THE CHIN (LOWER) WINDOW IS BOLTED IN?

A

LOWER WINDOW MAY BE REMOVED EASILY FOR MX TO ACCESS FRONT EVAPORATOR IN THE B4

52
Q

BEFORE ENGINE START, WHEN THE INDEPENDANT ALTERNATOR IS OFFLINE, HOW DOES THE FADEC RECIEVE AC CURRENT FOR START?

A

FROM THE STATIC INVERTER IN THE MASTER ELECTRICAL BOX UNDER THE REAR CARGO COMPARTMENT
