Explain the prestart check:
- Seats and control pedals - ADJUST and SECURE
- Seat belts - FASTEN
NOTE: Copilot seat belts shall be fastened in all cases
1. Rotor brake - RELEASE, fully forward
2. Fuel shut-off lever - FORWARD, plastic guard condition
3. Twist grip - IDLE position
4. Hydraulic cut-off switch (collective) - ON
5. [EMER SW] - ON
6. Engine starting selector - OFF
7. [BAT EPU] and [DCT/BAT] - ON
8. [W/LT TEST] - PERFORM
9. [FIRE TEST] - PERFORM, CHECK
10. [ACCU TST] - PRESS for 2 sec.
11. CWP lights - 10 lights: FUEL P, GENE, PITOT, HORN, SERVO, HYD1, HYD2, ENG P, MGB P, TWT GRIP
12. [SERVO TEST] - PRESS
13. VEMD - CHECK: - 3-data page: no message
- Vehicle page: no message
- Battery voltage > 22V
- Bleed valve flag
14. Control pedals - free travel, then left pedal 2 cm forward
15. Cyclic pitch - CENTER, friction adjusted
16. Collective pitch - LOCK, friction adjusted
17. Heating, demisting - OFF
Explain the engine starting procedure:
- CWP - CHECK GOV light out
- [FUEL PUMP] - ON
- [A/COL LT] - ON
- Cyclic control - HAND ON
After 30 sec: - Engine starting selector - ON position
- Engine parameters - CHECK:
- Ng increases
- T4 remains below its limits
- Rotor turns at Ng <= 25%
- Engine oil pressure increases
When Ng >= 67% - CWP - CHECK: SERVO, ENG P, HYD1, HYD2, MGB P lights go out
- [PITOT] - ON and PITOT light out
- [FUEL P] - OFF, check FUEL P light out
- Engine starting selector guard - SET
- All necessary systems - ON - TESTED
At Ng > 60 % the VEMD upper screen automatically switches to FLI display
Explain the Run up check:
- Hydraulic check - [SERVO TEST] - PRESS: SERVO light comes on
- Twist grip - FLIGHT position
When Nr >= 340 rpm - [HORN] - ON, HORN light out, CHECK audio warning OFF for Nr > 360 rpm
- Nr indication - CHECK in lower normal operating range
- [FIRE/TEST] - PERFORM, CHECK: ENG FIRE light + Gong sounds
- Parameter checks - No warning light illuminated, Electrical system voltage and current, Engine oil pressure
Explain the cranking procedure:
Can be performed after a failed or aborted start and can be used for check or maintenance purposes
1. Engine starting selector - OFF
2. Emergency fuel shut-off lever - Forward
3. Ng - CHECK <= 10%
4. [FUEL PUMP] - ON
5. [CRANK] - PRESS for 20 sec. max
6. [FUEL PUMP] - OFF
DO not crank the engine with the emergency fuel shutoff valve closed or with the fuel pump off as this could damage the engine high pressure fuel pump
Explain the before takeoff checks:
- Doors - Closed
- Collective, cyclic friction locks - as required
- Landing light - AS REQUIRED
- Temperature and pressures - NORMAL RANGE
- CWP - ALL lights OFF
- Collective - UNLOCKED
- Heating, demisting - AS REQUIRED
Adjust collective and cyclic friction locks so that friction loads are felt by the pilot when moving the flight controls
Explain the approach procedure:
- Landing light - AS REQUIRED
- All parameters - CHECK
- Heating, demisting - AS REQUIRED
Explain the engine and rotor shutdown procedure:
- Cyclic stick - NEUTRAL
- Collective pitch - LOCK
- Twist grip - IDLE position
- Engine oil cooling - WAIT for 30 sec.
- [PITOT], [HORN], landing light - OFF
- Non-required systems [AVIONOCS] - OFF
- Engine starting selector - OFF
- [GENE] - OFF
When rotors have stopped: - Yaw load compensator check:
- Right pedals moves forward with no or little force
- [ACCU TST] - PRESS 2 sec.
- Pedals can be re-centered - CHECK
* Yaw load compensator maintenance action required if before [ACCU TST] is pushed the right pedal cannot be moved forward
Before leaving the helicopter: - VEMD - CHECK of Flight Report page data:
- [BATT] buttons - OFF
What is the fuel tank capacity?
540 liters, 142.7 US gal, 941 pounds
What is the fuel burn rate?
33%/hour
What is the flight time remaining once the yellow area is reached?
15 min
