# Gear And Hydraulics {{< callout context="caution" title="IMPORTANT!" icon="outline/alert-triangle" >}} Token Variables - along with the [Gauge API](../../gauge-api/) - have been deprecated in Microsoft Flight Simulator 2024 in favour of the new [Vars API](../../../vars-api/vars-api/) and [Event API](../../../event-api/event-api/), which work with the more extensive and supported [Simulation Variables](../../../../simvars/simulation-variables/) and [Key Events](../../../../key-events/key-events-index/). {{< /callout >}} This page lists the available **landing gear and hydraulics** [Token Variables](../token-variables/) for use when creating gauges using {{< glossterm >}}wasm{{< /glossterm >}} / C++. ### Brakes {{< table-wrapper >}} | Parameters | Universal Var Member | Description | |---|---|---| | `ANTISKID_BRAKES_ACTIVE` | `b` (BOOL) | Whether the anti-skid brakes are active (TRUE, 1) or not (FALSE, 0). | | `AUTOBRAKES_ACTIVE` | `b` (BOOL) | Whether the auto-brakes are active (TRUE, 1) or not (FALSE, 0). | | `BRAKE_DEPENDENT_HYDRAULIC_PRESSURE` | `n` (FLOAT) | The brake dependent hydraulic pressure, in {{< glossterm >}}psf{{< /glossterm >}}. | | `BRAKE_IND` | `n` (FLOAT) | Whether the break indicator is on (TRUE, 1), or not (FALSE, 0). Note this is not a "true" bool, and 0 is false, while greater than 0 up 16384 is true. | | `BRAKES_LEFT_POS` | `n` (FLOAT) | The amount that the left brakes are being applied as a value between 0 and 32768. | | `BRAKES_LEFT_POS_EX1` | `n` (FLOAT) | The amount that the left brakes are being applied, without taking into consideration the parking brake, as a value between 0 and 32768. | | `BRAKES_RIGHT_POS` | `n` (FLOAT) | The amount that the right brakes are being applied as a value between 0 and 32768. | | `BRAKES_RIGHT_POS_EX1` | `n` (FLOAT) | The amount that the right brakes are being applied, without taking into consideration the parking brake, as a value between 0 and 32768. | | `PARKING_BRAKE_POS` | `n` (FLOAT) | The parking brake position, expressed as a value between 0 (off) and 32768 (full on). | | `REJECTED_TAKEOFF_BRAKES_ACTIVE` | `b` (BOOL) | Whether the rejected takeoff brakes are currently active (TRUE, 1) or not (FALSE, 0). | {{< /table-wrapper >}} ### Landing Gear {{< table-wrapper >}} | Parameters | Universal Var Member | Description | |---|---|---| | `GEAR_EMERGENCY_HANDLE_POSITION` | `b` (BOOL) | Whether the emergency brake handle is applied (TRUE, 1) or not (FALSE, 0). | | `GEAR_HANDLE_POS` | `n` (FLOAT) | Whether the gear handle is applied (> 0) or not (0). | | `GEAR_POS_AUX` | `n` (FLOAT) | The amount that the auxiliary gear is extended, expressed as a value between 0 (not extended) and 16384 (fully extended). | | `GEAR_POS_LEFT` | `n` (FLOAT) | The amount that the left gear is extended, expressed as a value between 0 (not extended) and 16384 (fully extended). | | `GEAR_POS_NOSE` | `n` (FLOAT) | The amount that the nose gear is extended, expressed as a value between 0 (not extended) and 16384 (fully extended). | | `GEAR_POS_RIGHT` | `n` (FLOAT) | The amount that the right gear is extended, expressed as a value between 0 (not extended) and 16384 (fully extended). | | `GEAR_POS_TAIL` | `n` (FLOAT) | The amount that the tail gear is extended, expressed as a value between 0 (not extended) and 16384 (fully extended). | | `NOSEWHEEL_LOCK_ON` | `b` (BOOL) | Whether the nose wheel lock is engaged (TRUE, 1) or not (FALSE, 0). | | `STEER_INPUT_CONTROL` | `n` (FLOAT) | The position of the steering tiller between -1 and 1. | | `TAILWHEEL_LOCK_ON` | `b` (BOOL) | Whether the tail wheel lock is engaged (TRUE, 1) or not (FALSE, 0). | {{< /table-wrapper >}} ### Hydraulics {{< table-wrapper >}} | Parameters | Universal Var Member | Description | |---|---|---| | `HYDRAULIC_SYSTEM_INTEGRITY` | `b` (BOOL) | The hydraulic system integrity expressed as a {{< glossterm >}}percent_over_100{{< /glossterm >}} where 0 means a complete failure of the system and 1 means everything is working perfectly. | | `HYDRAULICS1_PRESSURE_PSF``HYDRAULICS2_PRESSURE_PSF``HYDRAULICS3_PRESSURE_PSF``HYDRAULICS4_PRESSURE_PSF` | `n` (FLOAT) | The hydraulics 1/2/3/4 pressure in {{< glossterm >}}psf{{< /glossterm >}}. | | `HYDRAULICS1_RESERVOIR_PCT``HYDRAULICS2_RESERVOIR_PCT``HYDRAULICS3_RESERVOIR_PCT``HYDRAULICS4_RESERVOIR_PCT` | `n` (FLOAT) | The hydraulics system reservoir, as a {{< glossterm >}}percent_over_100{{< /glossterm >}}. | {{< /table-wrapper >}}
