Aircraft Electrics Variables
The tables below indicate the properties for the Simulation Variables that can be used to get and set variables related to the electrical system of the aircraft. For information on the units listed for each variable, please see here: Simulation Variable Units
You can find a complete index of all available SimVars here: SimVar Index
The SimVars below are all related to the aircraft electrical system (including lights). Large parts of this system are setup using the [ELECTRICAL] section of the system.cfg file, and many may also require the use of the different to retrieve and edit their values.

SET 0 sets the switch of every batteries like FSX. | Bool |

Circuits
This section contains the SimVars related to the electrical circuits. Note that many of them will require the name of the component that they target. This name is given using the following format:
[SimVar]:'[COMPONENT_NAME]'_nFor example:
(A:ELECTRICAL CIRCUIT VOLTAGE:'Circuit_1'_n, Volts)NOTE
Many of the circuit SimVars here will refer to a specific type of circuit, in which case the index - if supplied - is local to the type. For example, if you have three circuits of the type CIRCUIT_AVIONICS and two of the type CIRCUIT_LIGHT_LANDING, then you have five circuits in total. If you want to target the circuit for the second landing light, then you would supply the index “2”, not “5”. Also note that for the modern electrical system (v2+), you can supply 0 for an index to target all circuits of the given type (the legacy v1.00 electrical system will treat index 0 the same as index 1, and the FSX electrical system does not have circuit indices).

ALTERNATOR CONNECTION ON | v2+:Generator namev1.00:Alternator indexBus index | This will be true if the alternator/generator is connected. Requires an alternator index or a generator name, and for legacy systems it will also require a bus index. | Bool | |
GENERAL ENG MASTER ALTERNATOR | FSX system:Alternator indexv1.00:Alternator indexv2+:Generator name or index | The alternator or generator switch position, true if the switch is ON. Requires alternator index or a generator name (or index) when referencing. | Bool |
APU
| Simulation Variable | Index | Description | Units | Settable |
|---|---|---|---|---|
APU BLEED PRESSURE RECEIVED BY ENGINE | Engine Index | Bleed air pressure received by the engine from the APU. | Pounds per square inch (psi) | |
APU GENERATOR ACTIVE | Generator Index | Set or get whether an APU is active (true) or not (false). Takes an index to be able to have multiple generators on a single APU. | Bool | |
APU GENERATOR SWITCH | Generator Index | Enables or disables the APU for an engine. Takes an index to be able to have multiple generators on a single apu. | Bool | |
APU ON FIRE DETECTED | N/A | Will return true if the APU is on fire, or false otherwise. | Bool | |
APU PCT RPM | N/A | Auxiliary power unit RPM, as a percentage | Percent Over 100 | |
APU PCT STARTER | N/A | Auxiliary power unit starter, as a percentage | Percent Over 100 | |
APU SWITCH | N/A | Boolean, whether or not the APU is switched on. | Bool | |
APU VOLTS | N/A | The volts from the APU to the selected engine. Takes an index to be able to have multiple generators on a single APU. | Volts | |
BLEED AIR APU | N/A | Boolean, returns whether or not the APU attempts to provide Bleed Air. | Bool |
