In-depth and generalised operating procedures, inspired by the real-world manual.

Caution

SIMULATION USE ONLY - DO NOT USE THIS DOCUMENTATION ON A REAL AIRCRAFT

Sim Operation Remarks
  1. Make sure your controls are correctly configured for flight. Please check the Hardware Configuration page for more information.
  2. Make sure your hardware has all the necessary keybinds configured. Please check the Keybinds Guide page for more information.
  3. The Rotor Brake keybind must be correctly configured, as it may interfere with background functions. Find ROTOR BRAKE in your controls options, * Configure keybind for Press+Hold (input repetition must be enabled) activation. * Alternatively, you may use TOGGLE ROTOR BRAKE to lock it into position (ON/OFF without requiring input repetition).
  4. Please DO NOT USE HELICOPTER THROTTLE AXIS , and unassign this from your hardware.
General

This section contains instructions and recommended procedures that are peculiar to the operation of this helicopter.

Flight Restrictions

The minimum, normal, maximum and cautionary operation ranges for the helicopter and its subsystems are indicated by instrument markings, placards and decals.

Flight Planning

Refer to Performance Data (FOR EDUCATIONAL PURPOSES ONLY) to determine required fuel, airspeeds and power settings for takeoff, climb, cruise, and hovering and landing data necessary to accomplish the mission.

Note

Please note that failures are not simulated in this addon, and the flight model is limited by the capabilities of the simulator itself. Therefore, performance charts may not translate accurately into the simulated environment.

Mass and Balance

The takeoff and anticipated landing gross mass and balance should be obtained before takeoff and checked against mass and load limits, and center of gravity limitations.

Note

See EFB > Aircraft > Flight Performance > Mass and balance

Preflight Check

The preflight check is not a detailed mechanical inspection, but essentially a visual check \ of the helicopter for correct condition. When unusual local conditions dictate, the extent and/or frequency of this check shall be increased as necessary to promote safe operation.

Exterior Check

The exterior check is laid out as a walk-around check, starting forward right at the pilot’s door, proceeding clockwise to the tail boom, to the left hand side (including the upper and lower areas of the helicopter) and being completed at the helicopter nose area.

(1. FUSELAGE - RIGHT SIDE, 2. TAIL BOOM, 3. FUSELAGE - LEFT SIDE, 4. CABIN TOP, 5. NOSE)

Note:

  • The helicopter should be headed into the wind before starting engines.
  • The area around the helicopter should be clear of all foreign objects.
  • To avoid excessive drain on the helicopter battery, particularly during cold weather, all ground operations should be conducted using an external power unit (EPU).
  • When the battery is used, the operation of electrical equipment should be kept \ to a minimum.

Starting Engines

Note

  • If, for any reason, a starting attempt is discontinued the entire starting sequence \ must be repeated from the beginning.
  • When a starting attempt is aborted but TOT limits were not exceeded, wait 15 \ seconds after N1 has returned to zero before attempting restart to permit excess \ fuel to drain from combustion chamber.
  • Before starting engines, the operational hydraulic system shall always be preselected to system 2 (collective lever lock engaged).
Starting First Engine
Note

Operate only the controls of the corresponding engine.

Caution

IMMEDIATELY ABORT START FOR ANY OF THE FOLLOWING:

  • MAIN ROTOR IS NOT ROTATING AT 25% N1. (A SECOND AND THIRD START ATTEMPT MAY BE MADE. IF POWER TURBINE STILL F AILS TO ROTATE, DISCONTINUE ATTEMPT)
  • STAGNATED START (FUEL STARVATION).
  • TOT RISES ABNORMALLY AND RAPIDLY APPROACHES START LIMIT (927 °C).
  • TOT EXCEEDS 10-SECOND LIMIT WITHIN TEMPERATURE RANGE (811-927 °C).
  • NO POSITIVE ENGINE OR TRANSMISSION OIL PRESSURE INDICATIONS UPON REACHING IDLE SPEED (N1 59-65%).
  • IDLE SPEED IS NOT REACHED WITHIN 60 SECONDS UNLESS N1 AND N2 ARE ACCELERATING AND TOT IS WITHIN LIMITS.
  • HYD 2 WARNING LIGHT REMAINS ON UPON REACHING GROUND IDLE SPEED (60% NRo).

\ ABORT START PROCEDURE:

  7. If N1 decreases below 59%:
    1. Generator - OFF
    2. Power Lever - ADVANCE, N1 max 70%
    3. Generator - ON
Starting Second Engine

  3. Second Engine - FOLLOW PROCEDURE FOR FIRST ENGINE
  4. After EPU Starts:
  5. Battery Switch - ON
  6. EPU - CHECK DISCONNECTED

Flight Characteristics

Flight Controls
Caution

AVOID EXTREME CYCLIC STICK DISPLACEMENTS WHEN ON THE GROUND WITH ROTOR TURNING.

During ground operations with rotor turning, the cyclic stick must remain in the neutral position and the c ollective pitch lever in the full down position; however, for functional test purposes, minimum control movements are allowed.

Avoid extreme pedal movements during ground operations.
