Simulation Variables

Overview

There are two classes of simulation variables: aircraft and global data. The following tables list all the variables that can appear in XML based gauges, or used from the SimConnect APIs.

Aircraft Data

Notes (Gauges)

Aircraft data is referenced by A: in XML gauges. Some parameters take an index to determine which of a multiple of system is being queried. In XML gauges the syntax for adding an index is :N, for example:

FUEL TANK SELECTOR:index 

Notes (SimConnect)

Simulation variables are referenced from within SimConnect clients with the SimConnect_AddToDataDefinition call (see the SimConnect document for full details). When the units are listed as a structure or as a string, enter the empty string, or simply NULL, in the units parameter of this function call.

For example:

hr = SimConnect_AddToDataDefinition(hSimConnect, DEFINITION_1, "Kohlsman setting hg", "inHg");
hr = SimConnect_AddToDataDefinition(hSimConnect, DEFINITION_1, "Indicated Altitude", "feet");
hr = SimConnect_AddToDataDefinition(hSimConnect, DEFINITION_1, "Plane Latitude", "degrees");
hr = SimConnect_AddToDataDefinition(hSimConnect, DEFINITION_1, "Plane Longitude", "degrees");
hr = SimConnect_AddToDataDefinition(hSimConnect, DEFINITION_2, "Category", null);               \\ string
hr = SimConnect_AddToDataDefinition(hSimConnect, DEFINITION_2, "AI Waypoint List", null);       \\ structure

Notes (Multiplayer)

When Flight Sim World is running in multiplayer mode, only a small number of variables are communicated between aircraft. This is noted in the Multiplayer column (All aircraft or Shared Cockpit).

New Simulation Variables for Flight Sim World

The following variables are only available in the Flight Sim World SDK.

Simulation VariableDescriptionUnitsSettableMultiplayer
FLIGHT CONTROLS LOCKEDUser input is blocked, except for pause/exitBoolY-
PAYLOAD STATION DEFAULT WEIGHT:indexGets the payload station default weight for the given index.poundN-

PASSENGER HIDEHide the passenger in slotNumberY-
EMPHASIZE GAUGEGets (when read) or sets (when set) a list of gauge name(s) to emphasize to the player (i.e. flash).
When reading: returns a comma-separated list of gauges which should be emphasized at that point in time. The list also starts and ends with a comma, e.g.:
,altimeter_1,vertical_speed_1,
In gauge XML code, check whether to emphasize a particular gauge using an expression such as:
 (A:EMPHASIZE GAUGE, string) ',autopilot_1,' sstr 0 >= 

When setting: provide a comma-separated list of gauge names and durations (in seconds) to emphasize each for, as per below:
altimeter_1:5,vertical_speed_1:10
In addition to any gauges currently being emphasized, these two will also now be emphasized, until 5 and 10 seconds from now.
Names should be lowercase. "Standard" gauge names include:
  • adf_x

CHECKLIST STATEThe state of the 3d checklist model in the aircraft.
0 is initial position, usually on the dash in front of the user.
1 is the secondary position, usually in a side pocket or similar.
This is a number to allow more states in future if required. Use the key event TOGGLE_CHECKLIST to modify this and CHECKLIST VISIBLE.
NumberN-
CHECKLIST VISIBLEIf the 3d model of the checklist in the aircraft is visible.
If visible CHECKLIST STATE will determine where it is visible.
Use the key event TOGGLE_CHECKLIST to toggle this.
Note: The inverse of this determines if the UI checklist is visible.

EnumY-
EMPHASIZE PARTGets (when read) or sets (when set) a list of part name(s) to emphasize to the player (i.e. flash).
When reading: returns a comma-separated list of parts which are being emphasized at that point in time. The list also starts and ends with a comma, e.g.:
,throttle_lever_chk,left_mag,

When setting: provide a comma-separated list of part names (from max) and durations (in seconds) to emphasize each for, as per below:
throttle_lever_chk:5,left_mag:10
In addition to any parts currently being emphasized, these two will also now be emphasized, until 5 and 10 seconds from now.

Note that parts which are not suffixed with "_chk" may not highlight correctly as they might get batched with other parts.

Currently only the latest part to be added will be emphasized as only one part emphasis at a time is currently supported.

Notes

  1. These variables make most sense for aircraft with flight plans. If an aircraft does not have a flight plan, the value returned will be 0 (or false), or an empty string, depending on the units.
  2. These variables only make sense for aircraft generated by the traffic database, and so have schedules. If an aircraft does not have a schedule, the value returned will be 0 (or false), or an empty string, depending on the units.

Aircraft Engine Data

In the multiplayer Shared Cockpit mode the only supported index is 1, which means that the data is assumed to be identical for all engines. In single player mode engine indexes are from 1 to 4.

EMPHASIZE GAUGEGets (when read) or sets (when set) a list of gauge name(s) to emphasize to the player (i.e. flash).
When reading: returns a comma-separated list of gauges which should be emphasized at that point in time. The list also starts and ends with a comma, e.g.:
,altimeter_1,vertical_speed_1,
In gauge XML code, check whether to emphasize a particular gauge using an expression such as:
 (A:EMPHASIZE GAUGE, string) ',autopilot_1,' sstr 0 >= 

When setting: provide a comma-separated list of gauge names and durations (in seconds) to emphasize each for, as per below:
altimeter_1:5,vertical_speed_1:10
In addition to any gauges currently being emphasized, these two will also now be emphasized, until 5 and 10 seconds from now.
Names should be lowercase. "Standard" gauge names include:
  • adf_x
  • airspeed_x
  • altimeter_x (1 = barometric; 2 = altimeter)
  • annunciator_panel_x
  • aps_indicator_x
  • attitude_indicator_x
  • autopilot_x
  • cht_x
  • clock_x
  • compass_x
  • dme_x

EMPHASIZE PARTGets (when read) or sets (when set) a list of part name(s) to emphasize to the player (i.e. flash).
When reading: returns a comma-separated list of parts which are being emphasized at that point in time. The list also starts and ends with a comma, e.g.:
,throttle_lever_chk,left_mag,

When setting: provide a comma-separated list of part names (from max) and durations (in seconds) to emphasize each for, as per below:
throttle_lever_chk:5,left_mag:10
In addition to any parts currently being emphasized, these two will also now be emphasized, until 5 and 10 seconds from now.

Note that parts which are not suffixed with "_chk" may not highlight correctly as they might get batched with other parts.

Currently only the latest part to be added will be emphasized as only one part emphasis at a time is currently supported.

IS LATITUDE LONGITUDE FREEZE ON

True if the lat/lon of the aircraft (either user or AI controlled) is frozen. If this variable returns true, it means that the latitude and longitude of the aircraft are not being controlled by Flight Sim World, so enabling, for example, a SimConnect client to control the position of the aircraft. This can also apply to altitude and attitude.

Also refer to the range of KEY_FREEZE..... Event IDs.

CHECKLIST STATEThe state of the 3d checklist model in the aircraft.
0 is initial position, usually on the dash in front of the user.
1 is the secondary position, usually in a side pocket or similar.
This is a number to allow more states in future if required. Use the key event TOGGLE_CHECKLIST to modify this and CHECKLIST VISIBLE.
NumberN-
CHECKLIST VISIBLEIf the 3d model of the checklist in the aircraft is visible.
If visible CHECKLIST STATE will determine where it is visible.
Use the key event TOGGLE_CHECKLIST to toggle this.
Note: The inverse of this determines if the UI checklist is visible.

Units of Measurement

The following table gives the strings that are accepted by the SDK for units. All the strings in the same row are identical in meaning. Note that some strings have "per" spelled out, and some use "/", and note that a few contain hyphens or underscores.

Notes

When making object definitions in SimConnect, it is possible to request the units that the values are to be received in. All the units in the tables below under one heading (such as Frequency or Speed) can be used as appropriate to the client application, except those under Miscellaneous Units. See the SimConnect documentation for more details.
