Q

PROCEDURE IN CASE OF FAILED / ABORTED START

CRANKING

A
  1. Engine starting selector - OFF
  2. Emergency fuel shut-off lever - FORWARD
  3. Ng - CHECK below 10%
  4. [FUEL PUMP] - ON
  5. [CRANK] - PRESS for 20 sec. max
  6. [FUEL PUMP] - OFF

When starting the engine, the starter time is the time between selecting the engine starting selector to ON and the engine igniting.

When performing an engine ventilation, the starter time is the duration that the [CRANK] is pressed.

To prevent starter overheat damage, limit starter time to the following:

    • 30 seconds ON - 60 seconds OFF
    • 30 seconds ON - 60 seconds OFF
    • 30 seconds ON - 30 minutes OFF

The 30 minutes cooling period is required before beginning another starting cycle

Q

WHAT IS BEST CLIMB Vy?

A

Above 100 ft (30 m), for maximum climb performance, select up to MCP and optimum climbing speed (Vy):

IAS kt = 65 kt at 0 Hp - (1 kt / 1000 ft). IAS km/h = 120 km/h at 0 Hp - (2 km/h per 300 m)

Q

DEMONSTRATED WIND ENVELOPE FOR STARTING AND STOPPING ROTOR

(Not Limitation)

A

40 knots from any direction

50 knots for direct headwind

Hovering with winds from any direction up to 17 kt has been demonstrated over the entire flight envelope although it is not to be taken as a limit. For example hover at sea level at maximum gross weight and for all CG locations has been substantiated at 30 kt

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 Ng 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 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
