Overview

Simulation Variables

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

Unless the Units column in the following table identifies the units as a structure or a string, the data will be returned by default in a signed 64 bit floating point value. The SimConnect_AddToDataDefinition has an optional parameter to change this to a signed 32 or 64 bit integer, or a signed 32 bit floating point value.

Notes (Multiplayer)

When the simulation 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).

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.

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.

Carrier Operations

LAUNCHBAR POSITION Installed on aircraft before takeoff from a carrier catapult. Note that gear cannot retract with this extended. 100 = fully extended. Refer to the document Notes on Aircraft Systems. Percent_over_100 N -
LAUNCHBAR SWITCH If this is set to True the launch bar switch has been engaged. Bool N -
LAUNCHBAR HELD EXTENDED This will be True if the launchbar is fully extended, and can be used, for example, to change the color of an instrument light. Bool N -
NUMBER OF CATAPULTS Maximum of 4. A model can contain more than 4 catapults, but only the first four will be read and recognized by the simulation. Number N -
CATAPULT STROKE POSITION:index Catapults are indexed from 1. This value will be 0 before the catapult fires, and then up to 100 as the aircraft is propelled down the catapult. The aircraft may takeoff before the value reaches 100 (depending on the aircraft weight, power applied, and other factors), in which case this value will not be further updated. This value could be used to drive a bogie animation. Number N -
HOLDBACK BAR INSTALLED Holdback bars allow build up of thrust before takeoff from a catapult, and are installed by the deck crew of an aircraft carrier. Bool N -
BLAST SHIELD POSITION:index Indexed from 1, 100 is fully deployed, 0 flat on deck Percent_over_100 N -

TAILHOOK HANDLE True if the tailhook handle is engaged. Bool N -
SURFACE RELATIVE GROUND SPEED The speed of the aircraft relative to the speed of the first surface directly underneath it. Use this to retrieve, for example, an aircraft's taxiing speed while it is moving on a moving carrier. It also applies to airborne aircraft, for example when a helicopter is successfully hovering above a moving ship, this value should be zero. The returned value will be the same as GROUND VELOCITY if the first surface beneath it is not moving. Feet_per_second N -
