Simulator data
What the Hub reads from the simulator for this instrument, and what the instrument sends back. Names are the simulators' own: MSFS SimVars and events, X-Plane datarefs and commands.
Reads
| Value | MSFS | X-Plane |
|---|---|---|
| Nose gear position, 0 up .. 1 down and locked | GEAR CENTER POSITION (percent over 100) | sim/flightmodel2/gear/deploy_ratio[0] |
| Left gear position, 0..1 | GEAR LEFT POSITION (percent over 100) | sim/flightmodel2/gear/deploy_ratio[1] |
| Right gear position, 0..1 | GEAR RIGHT POSITION (percent over 100) | sim/flightmodel2/gear/deploy_ratio[2] |
| Retractable gear (1/0) (bool) | IS GEAR RETRACTABLE (bool) | sim/aircraft/gear/acf_gear_retract |
| Gear handle down (1/0) (bool) | GEAR HANDLE POSITION (bool) | sim/cockpit2/controls/gear_handle_down |
Sends
| When you… | MSFS | X-Plane |
|---|---|---|
| Tap on the GEAR knob, or mapped 'Gear lever' | GEAR_TOGGLE | sim/flight_controls/landing_gear_toggle |
Add-on aircraft with their own systems may use other variables; the Hub reads the standard ones.
Changes
The instrument's version counts what its faces share (the case, the mechanism, the data, the sounds); a face's own version counts that face alone.
