YAW STRING
+
=== YAW STRING ===
 
Your helicopter is equipped with a high tech. turn coordination system consisting of a short piece of yarn attached with scotch tape to the front of the bubble. The yaw string shows the relationship of the slipstream to the orientation of the helicopter and can be used to help coordinate turns with the pedals during cruise flight. During coordinated cruise flight, the yarn should be oriented vertically. If you have too much or too little left or right pedal, the yaw string will bend to one side or the other. Apply pedal in the direction you want the string to move. For example, if the yaw string is leaning left, you should apply more right pedal to move it back to the vertical position. You will typically need to adjust pedals in response to changes in collective, or during turns. The yaw string should only be used during cruise flight, and should not be relied on during hovering or low speed flight.

HUD
 
−
When you first wear the HUD it will be dark and "disconnected" will displayed to indicate the HUD has not connected to an aircraft. When you sit in either the pilot (right) or co-pilot (left) seat, the HUD will connect and light up. The HUDs of the pilot and copilot/passenger show identical flight data including control positions. There are three main parts of the HUD: gauges on the top, switches for electrical systems in the middle, and flight controls on the bottom.
 
−
* The gauges starting at the top are:
 
  
−
Fuel Quantity - Shows remaining fuel. Only active when master switch is on.
+
=== HUD ===
−
Amps/Volts - The "Amps" side shows current power usage. Numbers below 0 indicate a drain on the battery, numbers above 0 indicate a charge to the battery. The "Volts" side shows the current health of the battery. 14 volts indicates a full charge, 8 volts indicates a depleted battery. Electrical systems including the starter will begin to fail when you are near 8 volts. This gauge is only active when master switch is on.

When you first wear the HUD it will be dark and "disconnected" will displayed to indicate the HUD has not connected to an aircraft. When you sit in either the pilot (right) or co-pilot (left) seat, the HUD will connect and light up. The HUDs of the pilot and copilot/passenger show identical flight data including control positions. There are three main parts of the HUD: Main Flight Controls, Flight Instruments and Fuel/Engine/Electrical Instruments.
−
Aircraft ID - Shows the tail number of the aircraft the HUD is connected to. "--" will be displayed when disconnected. An indicator light to the left of the ID number shows the current connectivity status. A green light indicates normal connectivity, while a yellow or red light indicates no connectivity. It is normal to see a yellow or red indication for one or two seconds during a sim crossing.
+
 
−
HOBBS meter - Shows total time on your aircraft in hours and tenths of hours. Accumulates time only while engine is running.
+
=== Main Flight Controls ===
−
Altimeter - Shows altitude in feet.
+
 
−
RPM - Shows speed of engine and rotor in RPM. The outer scale with the long needle shows engine RPM in hundreds. The inner scale with the short needle shows the rotor RPM in hundreds. The green arc indicates the normal operating RPM range.
+
The main part of the HUD shows the tail-number and HOBBS time of your aircraft on top, and three boxes with a red dot showing your flight control positions. The flight controls are:
−
Airspeed - The middle gauge shows the airspeed in mph. The red line is the "never exceed" speed.
+
 
−
Vertical Speed Indicator (VSI) - Shows the current rate of descent or climb in hundreds of feet per minute.
+
# Collective - Collective controls the total thrust the helicopter is producing. Drag the red dot with the mouse to move the collective. You can also use the Up/Down arrow keys. The red dot will show current collective position regardless of which method you use to manipulate it.
−
Manifold Pressure (MP) - Shows current manifold pressure (MP) indicating power being produced by the engine. The red line is a never exceed value. Exceeding this value in flight can lead to a dangerous loss of rotor RPM.
+
#Cyclic - Cyclic controls the direction that thrust is directed. Drag the red dot with the mouse to move the cyclic. In cruise flight, turns should be performed primarily with cyclic, with the pedals used for trim.
−
Inclinometer - The ball-in-tube display between the VSI and MP gauges can be used to coordinate turns while in cruise flight. In normal cruise or during a turn the ball will move to the side that needs more pedal. Think "step on the ball". When the ball is centered, you have exactly the right amount of pedal. The information displayed by the ball is similar to the yaw string taped to the front of the bubble.
+
#Anti-Torque - Anti-Torque (pedals) is used to control the tail rotor thrust. Use the mouse in the horizontal bar to set pedal position, or use the Left/Right arrow keys to control anti-torque. The pedals should be used for turns during hovering flight, and for trim using the yaw string or inclinometer while in cruise flight.
−
* The switches are:
+
 
−
Master Battery - Main electrical switch for aircraft. Don't forget to turn this off after shutting down or you will drain your battery..
+
=== Flight Instruments ===
−
Master Generator - Enables recharging of the battery. Under normal conditions, this should always be turned on with the master battery. The generator only produces power once the engine RPM is high enough.
+
 
−
Fuel Pump - Pumps fuel to the engine while the engine is off. Must be on to prime engine, and should remain on in flight.
+
The flight instruments part of the HUD is opened/closed by pressing the "INST" button on the left side of the main HUD.  From left-to-right starting on the top row the instruments are:
−
Governor - The governor automatically adjusts the throttle to keep engine RPM in in the green arc as you adjust collective. It should be turned on at the end of the start-up sequence.
+
# Fuel Flow - This instrument shows the fuel flow in gallons/hour on the outer arc.  The inner green arc can be used for leaning.  Once in cruise, the engine can be leaned until the MP matches the value shown on the green arc. Full rich should be used for takeoff and landing.
−
Beacon - Turns on the flashing beacon on the belly of the aircraft.
+
# Manifold Pressure - The manifold pressure is shown in inches of Hg.  Manifold pressure is an engine of the power output of the engine.
−
Nav - Turns on the nav lights on the sides and tail of the aircraft.
+
# Engine/Rotor RPM - The long needle marked "E" shows the engine RPM on the outer scale. The short needle marked "R" shows the rotor RPM on the inner scale.  The engine RPM should be between 2800 and 3000 RPM for normal flight.
−
Ldg & Taxi - Turns on the landing and taxi lights on the front of the aircraft. You need to enabled "Advanced Lighting" in your preferences to see the spot light effect on the ground in front of helicopter.
+
# VSI - Vertical speed in feet/minute.
−
* Flight controls are:
+
# Altitude - Altitude above sea level in feet.
−
Start - Press and hold this to start engine. The engine must be primed and in the proper state for the start to be successful. There must also be adequate charge on the battery. The starter drains power quickly, so do not use longer than necessary.
+
# Airspeed - Airspeed in Miles/Hour.
−
Throttle - Controls the throttle. Normally you only need to manually control (by dragging the red dot with the mouse) this at start-up and shutdown. In normal flight conditions the governor will automatically control throttle for you. There is also an "idle lock" feature that is activated by click on the box with the word "idle" under the throttle. This will lock the throttle in idle position for practice autorotations.
+
 
−
Collective - Collective controls the total thrust the helicopter is producing. Drag the red dot with the mouse to move the collective. You can also use the Up/Down arrow keys. The red dot will show current collective position regardless of which method you use to manipulate it.
+
=== Fuel/Engine Instruments ===
−
Cyclic - Cyclic controls the direction that thrust is directed. Drag the red dot with the mouse to move the cyclic. In cruise flight, turns should be performed primarily with cyclic, with the pedals used for trim.
+
 
−
Anti-Torque - Anti-Torque (pedals) is used to control the tail rotor thrust. Use the mouse in the horizontal bar to set pedal position, or use the Left/Right arrow keys to control anti-torque. The pedals should be used for turns during hovering flight, and for trim using the yaw string or inclinometer while in cruise flight.
+
The fuel/engine instruments part of the HUD is opened/closed by pressing the "FUEL" button on the right side of the main HUD. From the top of the HUD these instruments are:
−
Rotor Break - Used to slow down the rotors after engine is shut down. Should also be used during start-up to prevent damage to main rotor blades.
+
 
−
Mixture - Controls the fuel/air mixture to the engine. See the start-up procedure for information on how to use it.
+
# Fuel Quantity
−
Mags - Turns the magnetos on/off. There are both left and right magnetos. In normal flight you want to use both.
+
# Cylinder head temperature
−
FUEL SYSTEM
+
# Oil temperature (top), oil pressure (lower left), fuel pressure (lower right)
 +

=== FUEL SYSTEM ===
 
The fuel cap is located on the left side of the aircraft behind the passenger door. The fuel cap must be removed before servicing the aircraft. You can use any compatible refueling system (including typing "refuel" in local chat). For more control over your refueling, you can use the "SA AvGas Canister" bundled with this aircraft. Rez the canister within 10m of your aircraft and click on the canister. It will search for nearby aircraft which have had their fuel caps removed and display a list by N-Number. Choose the N-number of the aircraft you wish to fuel. Click the canister again to get a menu of refueling options. Refueling options include:

ELECTRICAL SYSTEM AND BATTERY CHARGER
+
=== ELECTRICAL SYSTEM AND BATTERY CHARGER ===
 
This aircraft uses a 14V electrical system. The current status of the electrical system is displayed on the top gauge of the HUD. The scale on the left side labeled AMPS shows the current rate of power consumption (or charge), while the right side labeled "VOLTS" shows the current charge on the battery. Both gauges only register when the master switch is on. All electrical devices use power and will drain the battery. The starter and the landing/taxi lights place the highest load on the battery. Below 9 volts, electrical devices including the starter will begin to fail or be less effective. Care must be taken to turn off the master switch after flight or the battery will be dead by the next flight.

An engine driven generator recharges the battery during flight. It is enabled by switching on the Generator switch on the HUD. The amount of power generated depends on engine RPM, and very little power is generated at low RPM levels. For this reason, it is best to turn off non-essential electrical equipment while idling.

A recharging system is provided to recharge the battery and/or perform a jump start if the battery is depleted. To use the recharger, you must first remove the cap on the electrical port located to the left of the passenger seat near the back. You can then rez the "SA Battery Recharger" near the aircraft. Click on the power pack to select and connect to an aircraft. Once connected, it will automatically begin charging. Leave the master switch off in the aircraft while charing to minimize recharge time. A red light on the power pack indicates that the battery is being charged, while a green light indicates that the recharge is complete. An indicator on the power pack shows the current charge on the aircraft battery.

MAIN MENU
+
=== ELT ===
 +
This aircraft is equipped with an on-board ELT (Emergency Locator Transmitter). The ELT is located behind the baggage compartment with a small antenna mounted on the top of the fuselage. Controls for the ELT are on the main console below the Low RPM Warning light. The controls consist of a light that will flash to indicate an ELT alarm has been triggered, and a two position switch. When the switch is in the "Off" position, no ELT alarms will be triggered. When the ELT is in the "Arm" position, a sudden impact will trigger an ELT signal which can be tracked by search and rescue personnel. Note: When fragile mode is enabled, an ELT alarm will cause the fire effects to persist until the ELT is turned off.

=== PAINTKIT SYSTEM ===
 +
 
 +
The paintkit system allows you to change the appearance of your helicopter. It is accessed through the @Paint sub-menu found on the @Admin menu. On this menu there are several built-in colors, and a "Custom" button to load a paint set from a separate "paintkit" prim. For custom designs you can either use a paintkit from a 3rd party vendor, or load your own texture set into the paint kit that came with your helicopter. To apply a paintkit, simply rez the paintkit near your helicopter and select "*Custom" from the @Paint menu. The helicopter will search for nearby paintkits and allow you to choose which you want to apply. Instructions on how to create your own custom paintkits can be found in the paintkit object.

The realism menu lets you enable or disable some of the RL helicopter flight characteristics. The features that can be enabled/disabled are:
−
Density - If enabled, density altitude will have an effect on aircraft performance. This comes in play when operating at high altitudes. At high altitudes hover height and climb rate will be reduced from their values at lower altitudes.
+
 
−
ETL (Effective Translational Lift) - If enabled, additional lift/performance is gained when forward airspeed goes above about 20 mph due to the main rotors constantly moving into clean air. When disabled, the additional performance is always available.
+
{| class=wikitable
−
Low RPM - When enabled, pulling excessive collective can result in decay of main rotor RPM. Decay can occur when the MP gauge is above red line. If this effect is disabled, rotor RPM will not decay when pulling collective beyond the red line on the MP gauge.
+
!Button
−
Torque - When enabled, torque effects from the main rotor will be experienced. Torque increases as collective is pulled and manifests as a right turning tendency. As a result, left pedal will need to be increased and maintained as collective is increased.
+
!Description
−
Vortex - When enabled, the helicopter can be subject to "vortex ring state" also known as "settling with power". This can occur when the helicopter is in a vertical descent of more than 300 feet/min with a forward speed of less than 30 mph while collective is at more than 50%. When vortex ring state occurs, the helicopter will experience a loss of lift and begin descending rapidly, even if additional collective is pulled.

Your helicopter is equipped with a high tech. turn coordination system consisting of a short piece of yarn attached with scotch tape to the front of the bubble. The yaw string shows the relationship of the slipstream to the orientation of the helicopter and can be used to help coordinate turns with the pedals during cruise flight. During coordinated cruise flight, the yarn should be oriented vertically. If you have too much or too little left or right pedal, the yaw string will bend to one side or the other. Apply pedal in the direction you want the string to move. For example, if the yaw string is leaning left, you should apply more right pedal to move it back to the vertical position. You will typically need to adjust pedals in response to changes in collective, or during turns. The yaw string should only be used during cruise flight, and should not be relied on during hovering or low speed flight.

2 HUD

When you first wear the HUD it will be dark and "disconnected" will displayed to indicate the HUD has not connected to an aircraft. When you sit in either the pilot (right) or co-pilot (left) seat, the HUD will connect and light up. The HUDs of the pilot and copilot/passenger show identical flight data including control positions. There are three main parts of the HUD: Main Flight Controls, Flight Instruments and Fuel/Engine/Electrical Instruments.

3 Main Flight Controls

The main part of the HUD shows the tail-number and HOBBS time of your aircraft on top, and three boxes with a red dot showing your flight control positions. The flight controls are:

  1. Collective - Collective controls the total thrust the helicopter is producing. Drag the red dot with the mouse to move the collective. You can also use the Up/Down arrow keys. The red dot will show current collective position regardless of which method you use to manipulate it.
  2. Cyclic - Cyclic controls the direction that thrust is directed. Drag the red dot with the mouse to move the cyclic. In cruise flight, turns should be performed primarily with cyclic, with the pedals used for trim.
  3. Anti-Torque - Anti-Torque (pedals) is used to control the tail rotor thrust. Use the mouse in the horizontal bar to set pedal position, or use the Left/Right arrow keys to control anti-torque. The pedals should be used for turns during hovering flight, and for trim using the yaw string or inclinometer while in cruise flight.

4 Flight Instruments

The flight instruments part of the HUD is opened/closed by pressing the "INST" button on the left side of the main HUD. From left-to-right starting on the top row the instruments are:

  1. Fuel Flow - This instrument shows the fuel flow in gallons/hour on the outer arc. The inner green arc can be used for leaning. Once in cruise, the engine can be leaned until the MP matches the value shown on the green arc. Full rich should be used for takeoff and landing.
  2. Manifold Pressure - The manifold pressure is shown in inches of Hg. Manifold pressure is an engine of the power output of the engine.
  3. Engine/Rotor RPM - The long needle marked "E" shows the engine RPM on the outer scale. The short needle marked "R" shows the rotor RPM on the inner scale. The engine RPM should be between 2800 and 3000 RPM for normal flight.
  4. VSI - Vertical speed in feet/minute.
  5. Altitude - Altitude above sea level in feet.
  6. Airspeed - Airspeed in Miles/Hour.

5 Fuel/Engine Instruments

The fuel/engine instruments part of the HUD is opened/closed by pressing the "FUEL" button on the right side of the main HUD. From the top of the HUD these instruments are:

  1. Fuel Quantity
  2. Cylinder head temperature
  3. Oil temperature (top), oil pressure (lower left), fuel pressure (lower right)

6 FUEL SYSTEM

The fuel cap is located on the left side of the aircraft behind the passenger door. The fuel cap must be removed before servicing the aircraft. You can use any compatible refueling system (including typing "refuel" in local chat). For more control over your refueling, you can use the "SA AvGas Canister" bundled with this aircraft. Rez the canister within 10m of your aircraft and click on the canister. It will search for nearby aircraft which have had their fuel caps removed and display a list by N-Number. Choose the N-number of the aircraft you wish to fuel. Click the canister again to get a menu of refueling options. Refueling options include: Check - Check the current fuel level. n Gal - Add n gallons (various quantities are listed) to the tank. Fill - Fill tank completely. Done - Exit menu and disconnect from aircraft. While a fuel canister is in use, it cannot be used by anyone else until they have selected "Done", filled the tanks, or a 5 min. timeout has expired. Note that fuel has weight and will affect the performance of your aircraft. One gallon weighs approximately 6 pounds. If carnying a lot weight, it is sometimes useful to fill the tanks only part way.

7 ELECTRICAL SYSTEM AND BATTERY CHARGER

This aircraft uses a 14V electrical system. The current status of the electrical system is displayed on the top gauge of the HUD. The scale on the left side labeled AMPS shows the current rate of power consumption (or charge), while the right side labeled "VOLTS" shows the current charge on the battery. Both gauges only register when the master switch is on. All electrical devices use power and will drain the battery. The starter and the landing/taxi lights place the highest load on the battery. Below 9 volts, electrical devices including the starter will begin to fail or be less effective. Care must be taken to turn off the master switch after flight or the battery will be dead by the next flight.

An engine driven generator recharges the battery during flight. It is enabled by switching on the Generator switch on the HUD. The amount of power generated depends on engine RPM, and very little power is generated at low RPM levels. For this reason, it is best to turn off non-essential electrical equipment while idling.

A recharging system is provided to recharge the battery and/or perform a jump start if the battery is depleted. To use the recharger, you must first remove the cap on the electrical port located to the left of the passenger seat near the back. You can then rez the "SA Battery Recharger" near the aircraft. Click on the power pack to select and connect to an aircraft. Once connected, it will automatically begin charging. Leave the master switch off in the aircraft while charing to minimize recharge time. A red light on the power pack indicates that the battery is being charged, while a green light indicates that the recharge is complete. An indicator on the power pack shows the current charge on the aircraft battery.

8 ELT

This aircraft is equipped with an on-board ELT (Emergency Locator Transmitter). The ELT is located behind the baggage compartment with a small antenna mounted on the top of the fuselage. Controls for the ELT are on the main console below the Low RPM Warning light. The controls consist of a light that will flash to indicate an ELT alarm has been triggered, and a two position switch. When the switch is in the "Off" position, no ELT alarms will be triggered. When the ELT is in the "Arm" position, a sudden impact will trigger an ELT signal which can be tracked by search and rescue personnel. Note: When fragile mode is enabled, an ELT alarm will cause the fire effects to persist until the ELT is turned off.

9 PAINTKIT SYSTEM

The paintkit system allows you to change the appearance of your helicopter. It is accessed through the @Paint sub-menu found on the @Admin menu. On this menu there are several built-in colors, and a "Custom" button to load a paint set from a separate "paintkit" prim. For custom designs you can either use a paintkit from a 3rd party vendor, or load your own texture set into the paint kit that came with your helicopter. To apply a paintkit, simply rez the paintkit near your helicopter and select "*Custom" from the @Paint menu. The helicopter will search for nearby paintkits and allow you to choose which you want to apply. Instructions on how to create your own custom paintkits can be found in the paintkit object.

10 MENUS

10.1 MAIN MENU

10.4 CHEATS MENU

The cheats menu accessed from the @Cheat button on the main menu allows you to access functions to bypass several of the normal procedures.

Button Description
Charge Bat. Charge the battery to full.
Panel Fix If you forget to put your side panels back on before you take off, you will "loose" the side panels. Use this button to get your side panels back.
Fast Start/Stop Use this button to start or stop your helicopter without going through the full procedure. You will still need to wait for the rotors to come to full speed when using Fast Start.
@Fuel Accesses a sub-menu that lets you set the fuel level to a specific level.

10.5 REALISM MENU

The realism menu lets you enable or disable some of the RL helicopter flight characteristics. The features that can be enabled/disabled are:

Button Description
Density If enabled, density altitude will have an effect on aircraft performance. This comes in play when operating at high altitudes. At high altitudes hover height and climb rate will be reduced from their values at lower altitudes.
ETL When ETL (Effective Translational Lift) is enabled, additional lift/performance is gained when forward airspeed goes above about 20 mph due to the main rotors constantly moving into clean air. When disabled, the additional performance is always available.
Low RPM When enabled, pulling excessive collective can result in decay of main rotor RPM. Decay can occur when the MP gauge is above red line. If this effect is disabled, rotor RPM will not decay when pulling collective beyond the red line on the MP gauge.
Torque When enabled, torque effects from the main rotor will be experienced. Torque increases as collective is pulled and manifests as a right turning tendency. As a result, left pedal will need to be increased and maintained as collective is increased.
Vortex When enabled, the helicopter can be subject to "vortex ring state" also known as "settling with power". This can occur when the helicopter is in a vertical descent of more than 300 feet/min with a forward speed of less than 30 mph while collective is at more than 50%. When vortex ring state occurs, the helicopter will experience a loss of lift and begin descending rapidly, even if additional collective is pulled.
Translate If enabled, the effects and compensation for translating tendency will be active. The net effect is that the left skid will hang slightly low in a hover.
