WHEN MUST BLADES BE TIED DOWN (Wind)?
Above 40 kt
HOW DO YOU CHECK ENGINE POWER IN HOVER BEFORE TAKEOFF?
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
HOW DO YOU PERFORM A FADEC/ENGINE HEALTH CHECK?
- 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

VEMD
(stands for)
Vehicle Engine Multifunction Display
WHAT VEMD SCREENS ARE AVAILABLE UNDER FLIGHT MODE?
- Engine
- Vehicle
- Flight Report
- HIGE
- HOGE
- Engine Power Check
WHERE ARE THE SCROLL BUTTONS LOCATED?
One on the collective
Right side of the VEMD unit
WHICH VEMD PAGE IS FOR THE ENGINE?
Top page
HOW MANY CHIP DETECTORS ARE ON THE ENGINE?
3
1 electrical
2 magnetic

3
1 boost pump .5 bar
1 low pressure pump 10 bar
1 high pressure pump 40 bar
WHAT PART DOES THE OIL FILTER HAVE TO DO WITH THE FUEL SYSTEM?
Heats the fuel so anti ice additive is not needed
(anti ice, Prist, only needed if below -20c)
EECU
(STANDS FOR)
ELECTRONIC
ENGINE
CONTROL
UNIT
WHAT DOES
THE EECU
DO?
- 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
WHAT IS
THE EECU
ALSO KNOWN AS?
“FADEC”
FULL AUTHORITY DIGITAL ENGINE CONTROL
OR
“DECU”
DIGITAL ENGINE CONTROL UNIT
HOW IS THE
EECU SUPPLIED
POWER?
2 channel gas generator
driven independent
alternator
HOW IS FUEL FLOW DETERMINED AND ADJUSTED?
By the EECU
WHAT IS AUTOMATIC
2nd CHANCE
ENGINE START?
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
WHAT DOES THE
DUAL STAGE STEPPED MOTOR DO?
Provides fuel flow modulation by driving a metering valve in the engine’s ‘hydro-mechanical unit’
EECU SYSTEM
FAILURES
3 LEVELS
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
WILL THE AIRCRAFT START WITH THE ROTOR BRAKE OUT OF THE LOCKED POSITION?
NO
IS THE OVERHEAD FUEL CUT-OFF LEVER SAFETEY WIRED?
No, a plastic cover protects it
HOW MANY HYDRAULIC PUMPS?
2
Left hand gear driven for upper portion of servos
Right hand belt driven for lower portion of servos
DO THE HYDRAULIC PUMPS USE SEPARATE RESERVOIRS?
YES
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
