AIRCRAFT MISC VARIABLES
The tables below indicate the properties for the Simulation Variables that can be used to get and set properties various miscellaneous properties related to the aircraft. For information on the units listed for each variable, please see here: Simulation Variable Units
NOTE: When Microsoft Flight Simulator 2024 is running in multiplayer mode, only a small number of variables are communicated between aircraft. Those variables that are available will say so in the description as being either for "All Aircraft" or for "Shared Cockpit".
You can find a complete index of all available SimVars here: SimVar Index

Aircraft Warnings
Aircraft Wear And Tear States
The SimVars listed here are all related to the [WEAR_AND_TEAR_SYSTEM]
. Most of the SimVars in this section require an ID value or name, as well as an (optional in some cases) index value. For example, if you are targeting the first piston engine of a two engine aircraft, then you could access it using the following formats:
1 (A:1:WEAR AND TEAR LEVEL:'PISTON_ENGINE'_n, percent)
1 (A:1:WEAR AND TEAR LEVEL:39, percent)
In both cases the wear and tear level check is being done on the 1st piston engine.
Simulation Variable | Description | Units | Settable |
---|---|---|---|
This SimVar is only valid during the pre-flight inspection phase of a flight, it is used to get (or set) the timer used for the inspection interaction (the circular progress bar) with a particular component. The component is identified by the given component ID/name and index. See the Wear And Tear Component IDs section for a full list of component names/IDs. |
Percent Over 100 | ||
WEAR AND TEAR EXPOSED PARTS LEVEL |
This SimVar returns the average wear and tear level of the exposed parts of the aircraft. The SimVar does not take any ID or index, as it is based on an internal calculation which takes data from multiple different sources, like the control surfaces, engines, etc... The SimVar returns a value between 0 and 1 where a 1 means that the aircraft is fully functional and undamaged, and a value of 0 means that the aircraft is seriously damaged and potentially unflyable. | Percent Over 100 | |
WEAR AND TEAR EXPOSED PARTS LOWEST LEVEL |
This SimVar returns the lowest wear and tear level of the exposed parts of the aircraft. The SimVar does not take any ID or index, as it is based on an internal calculation which takes data from multiple different sources, like the control surfaces, engines, etc... The SimVar returns a value between 0 and 1 where a 1 means that the aircraft is fully functional and undamaged, and a value of 0 means that the aircraft is seriously damaged and potentially unflyable. | Percent Over 100 | |
WEAR AND TEAR IS FAILED:id:index |
This SimVar will return TRUE (1) if the given component ID/name has failed completely, ie: it's "health" has fallen to zero and the component is considered by the simulation as "broken". If the component is still functioning, regardless of how "weak" it may be, then this will return FALSE (1). See the Wear And Tear Component IDs section for a full list of component names/IDs. |
Bool | |
WEAR AND TEAR IS WEAK:id:index |
This SimVar will return TRUE (1) if the given component ID/name is considered as being "weak", ie: it's "health" has fallen to a point where it could fail or break, and the compònent may have reduced functionality. If the component is not considered as "weak" (even if its wear and tear value is less than 1), then this will return FALSE (1). See the Wear And Tear Component IDs section for a full list of component names/IDs. |
Bool | |
WEAR AND TEAR LEVEL:id:index |
This SimVar returns the current wear and tear level of the component or system being referenced, where a value of 1 is a fully functional and undamaged component, and a value of 0 means that the component has failed. The SimVar requires an ID value or name, and may also use an additional index value to tell the simulation exactly which one of the components of the given type you are targeting. See the Wear And Tear Component IDs section for a full list of component names/IDs. |
Percent Over 100 | |
WEAR AND TEAR WEAK VALUE:id:index |
This SimVar returns the current "weakness" level of the component or system being referenced, where a value of 1 is a fully functional (but not necessarily undamaged) component, and a value of 0 means that the component has failed. If this value is less than 1, then the component will experience reduced functionality and may also be more prone to failure and breaking. The SimVar requires an ID value or name, and may also use an additional index value to tell the simulation exactly which one of the components of the given type you are targeting. See the Wear And Tear Component IDs section for a full list of component names/IDs. |
