Q

HOW DO YOU CHECK ENGINE POWER IN HOVER BEFORE TAKEOFF?

A

In HIGE at 5ft and before initiating forward flight, pull the collective pitch lever slightly to ensure that the N1 can increase by at least 1%, without exceeding the max. transient rating

Q

HOW DO YOU PERFORM A FADEC/ENGINE HEALTH CHECK?

A
  • The engine health check is performed in level flight MCP, heating and demisting system and ECS OFF.
  • Prefer an altitude where the engine is operating close to the N1 MCP limit.
  • Stabilize level flight MCP for at least 2 min. before initiating the engine health check.
  • Read the results displayed on VEMD after the end of the procedure.
  • The engine health check is satisfactory if:
  • TRQ MARGIN / TOT is above 0%, “GOOD” displayed, and
  • TRQ MARGIN / N1 is above 0%,“GOOD” displayed

28
Q

SCU

A

29
Q

VEMD

(stands for)

A

Vehicle Engine Multifunction Display

30
Q

WHAT VEMD SCREENS ARE AVAILABLE UNDER FLIGHT MODE?

A
  • Engine
  • Vehicle
  • Flight Report
  • HIGE
  • HOGE
  • Engine Power Check
31
Q

WHERE ARE THE SCROLL BUTTONS LOCATED?

A

One on the collective

Right side of the VEMD unit

32
Q

WHICH VEMD PAGE IS FOR THE ENGINE?

33
Q

HOW MANY CHIP DETECTORS ARE ON THE ENGINE?

A

3

1 electrical

2 magnetic

34
Q

HOW MANY FUEL PUMPS ARE THERE?

A

3

1 boost pump .5 bar

1 low pressure pump 10 bar

1 high pressure pump 40 bar

35
Q

WHAT PART DOES THE OIL FILTER HAVE TO DO WITH THE FUEL SYSTEM?

A

Heats the fuel so anti ice additive is not needed

(anti ice, Prist, only needed if below -20c)

36
Q

EECU

(STANDS FOR)

A

ELECTRONIC

ENGINE

CONTROL

UNIT

37
Q

WHAT DOES

THE EECU

DO?

A
  • Automatic engine starting, preventing TOT overlimit
  • Proportional integral power turbine speed control
  • Protection against engine surge and flame out during transients
  • Bleed valve monitoring
  • Protection against N1 and TOT overlimits
  • Failure detection and indication
  • Engine Health Check
  • N1 and N2 cycle counting
38
Q

WHAT IS

THE EECU

ALSO KNOWN AS?

A

“FADEC”

FULL AUTHORITY DIGITAL ENGINE CONTROL

OR

“DECU”

DIGITAL ENGINE CONTROL UNIT

39
Q

HOW IS THE

EECU SUPPLIED

POWER?

A

2 channel gas generator

driven independent

alternator

40
Q

HOW IS FUEL FLOW DETERMINED AND ADJUSTED?

A

By the EECU

41
Q

WHAT IS AUTOMATIC

2nd CHANCE

ENGINE START?

A

During the engine starting procedure if the ignition does not occur after 5 sec. when N1 greater than 17%, the EECU automatically stops the starting procedure, lets the N1 decrease to 10% and then automatically launches a new starting sequence. This sequence is totally managed by the EECU without pilot action.

NOTE
If the 2nd chance engine start fails, the pilot must carry out a new engine starting procedure as follows:
- engine starting selector to OFF position,
- wait 30 sec.,
- perform a cranking procedure
- perform the engine starting procedure

42
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’

43
Q

EECU SYSTEM

FAILURES

3 LEVELS

A

LEVEL 1 - FLASHING YELLOW GOV LIGHT

Reset EECU 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 EECU 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

Q

IS THE OVERHEAD FUEL CUT-OFF LEVER SAFETEY WIRED?

A

No, a plastic cover protects it

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

49
Q

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

A

There are NO accumulators

50
Q

WHAT DOES

THE DAY

SETTING DO?

Position lights on

51
Q

WHAT DOES

NIGHT 1 AND 2

SWITCH DO?

A

2 shuts off compass light

VEMD and CWP lights are dimmed accordingly

Position lights on

52
Q

WHEN DOES GEN TAKE OVER POWER PRODUCTION

A

When it produces .5 volt above battery

53
Q

FAN OPERATION TEMP

A

54
Q

TR SHAFT SPEED

55
Q
