Figure 1: S2-S Main HUD
Figure 2: S2-S Checklist HUD

The S2-S comes with two HUDS: a main HUD and a checklist HUD. These are described in the following sections.

1.1 Main HUD

The main HUD (see Figure 1) attaches in the lower right corner by default. When not sitting in an aircraft, the HUD will be dark with the word "Disconnected" showing on it. You can connect to a helicopter by sitting in it in the pilot or co-pilot seat. If the HUD fails to connect, or becomes disconnected for some reason, you can click on the aircraft window and choose "HUD Connect" from the main menu. The HUD consists of a core part with the flight controls, and three pop-out instrument sets.

The core of the HUD includes the following elements:

  • Collective - Red dot shows the current position of the collective which moves on a linear scale.
  • Cyclic - Red dot shows the current position of the cyclic which moves in 2-dimensions.
  • Anti-Torque - Red dot shows the current position of the anti-torque pedals which moves on a linear scale.
  • Crossing Status - Indicator dot in upper left corner shows green when the HUD is active, and yellow when inactive for a region crossing.
  • Tail Number - The tail number of the aircraft the HUD is connected to.
  • HOBBS - The HOBBS time (total operating time) of the aircraft the HUD is connected to.

The HUD popouts are controlled by buttons around the edge. Click one of the buttons to show or hide a cluster of instruments as described below:

Tab Description
INST. The main instrument tab is located on the left and includes the following instruments: Boiler Press. Differential, Turbine Press., Rotor/Engine RPM, Vertical Speed Indicator, Altimeter, Air Speed Indicator
FUEL The fuel tab is located on the right and includes gauges for the fuel level, boiler temp. and pressure, and the fuel flow control.
WEAPON The weapon tab is located on the top and includes controls for the deathray.

1.2 Checklist HUD

A checklist HUD with the preflight, flight and maintenance checklists is provided to assist with the preflight inspection, and as an alternative to the built-in checklist during flight operations. Arrows on the top can be used to change pages, and the "home" icon can be used to return to the first page.

The checklist HUD can be found in the aircraft box, or can be accessed from the helicopter @Get menu.

2 Seating Access Control

For the purpose of access control, there are two classes of seats: pilot, and copilot/passenger. Each class can be set to "R" to show it is in restricted mode or "G" for guest mode. When a seat class is in guest mode, anyone can use that seat. When A seat class is in "R" mode, only the owner, or those explicitly granted access can use the the seat. The access controls are found in the @Admin menu which is accessible only by the owner.

2.1 Seat Access Control

Seats included in each seat class are described in the following table:

Seat Class Description
Pilot Pilot
Crew Co-Pilot Seats/Passenger

2.2 Pilot Access List

Access to the helicopter can also be granted through a named-pilot access list via the @Admin menu. Pilots on this list have full access to the helicopter, except for the @Admin menu. They can pilot and/or service the helicopter. The following buttons in the @Admin menu are used to manage the access list:

  • Add - Adds a new pilot to the list. The pilot should be standing within 10m of the aircraft to be added.
  • Remove - Removes a pilot from the access list.
  • List - Lists all pilots who are currently on the access list.

3 Menus

Menus are only available to the owner and registered or guest pilots of the aircraft. In general button options beginning with an "@" are sub-menus, and options beginning with "( )" or "(*)" are options that can be toggled.

3.1 Main Menu

The buttons on the main menu are:

Button Description
Park/Unpark Make the aircraft non-physical/physical. Normally this occurs automatically when you sit in the aircraft, but this option can be used to control this manually.
Eject Select an occupant to eject
@Options Control various flight option settings.
@Get Get various things include HUD and manual/help notecards
HUD Connect Reestablish connectivity between helicopter and HUD if it becomes disconnected, or if you wear HUD while already seated.
@Admin Access owner-only options
@Cheat Displays the "Cheat" menu with options to bypass various procedures. See "CHEATS" below for more details.
@Realism Enable or disable "realism" features of the aircraft flight characteristics.
@REGISTER Access the aircraft registration menu. This button will only appear on the main menu if an N number had not yet been assigned. (aircraft must be parked/non-physical)
REPAIR! Repair helicopter after a boiler explosion. (only appears on main menu when there is damage to the helicopter)


The admin menu contains options only available to the aircraft owner. Buttons/Options are:

Button Description
Recal. W&B If you make any changes to the linkset, you should use this option to recalibrate the weight & balance for the scripts.
(?) Pilot Set pilot seat to guest (G) or restricted (M)
(?) Copilot Set copilot seat to guest (G) or restricted (M)
Add Pilot Add an authorized crew member. A maximum of 12 crew members can be registered. The crew member to be added should stand within 10m of aircraft to be recognized by the system.
Remove Pilot Remove a crew member from the authorized crew member list.
List Pilots List the authorized crew members.
@REGISTER Assign or changer your aircraft's registration. See "N-NUMBER ASSIGNMENT" in Section 1 for more details. (aircraft must be parked/non-physical)


The options menu is accessed from the @Options button on the main menu and is available to any registered pilot.

Button Description
(?) Controls Select a control scheme. Control schemes are discussed in the CONTROLS section near the beginning of this document.
(?) Skidlook Enable special down-facing camera (Useful for playing Game-of-Cones).
(?) GPS Show the GPS in the cockpit.
(?) Deathray Show the deathray mounted on the nose.
(?) Doors Show doors (disable to hide doors).
(?) Failures Set the failure level: N=No failures, P=Progress failures, but no new failures, 1-9=Failure rate
(?) Governor If enabled, the throttle will be controlled automatically while it full RPM. If disabled, all throttle control is manual.
(?) Fragile If enabled, a crash will cause helicopter to burst into flames and become non-responsive. Resets after a set time (or until ELT is turned off).
(?) CopilotCtrl Enable or disabled copilot controls
(?) Alerts If enabled, alert messages about collisions or other unsafe conditions will be given. If disabled, no alert messages will be issued.
(?) Dust If enabled, dust effects are produced when the aircraft is near the ground, water, or over a prim.


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.
Boiler Water Refill water in the boiler.
REPAIR! Repair helicopter after a boiler explosion.
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.


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
Battery If disabled, the battery will not run out.
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 If enabled, additional lift/performance is gained when forward airspeed goes above about 20 knots due to the main rotors constantly moving into clean air. When disabled, the additional performance is always available.
Torque When enabled, the main rotor produces torque that must be counteracted with tail rotor.
Low RPM When enabled, pulling excessive collective can result in decay of main rotor RPM.
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 knots 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 are disabled.
