Voltmeter
A round voltmeter showing the bus voltage, with the aircraft's green band and red low/high lines, and the reading to a tenth in a small window.

Features
- VOLTS DC dial, major marks every 4 V, minor every 1 V
- Green band and red lines from the aircraft profile (e.g. 24-32 V green on a 28 V system)
- Digital window with the voltage to a tenth
- Red X when the voltage is missing or stale
- Realistic needles (Settings): spring and slight vibration
- Night lighting: the face takes the panel's red flood light, the glareshield's warm light from above (stronger for instruments higher on the page) and its own light, a lamp hidden at the top of the case lighting the dial downward (Settings > Dimmers: Red flood light, Glareshield, Instruments (analog))
Your aircraft: Scale, green band and red lines from the profile's volts range. A generic profile (an aircraft the Hub doesn't know) gets wide default scales with no bands or red lines (20-32 V).
On the iPad
- No knobs: a tap on the face asks to change the instrument
Settings
- Global: Realistic needles
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 |
|---|---|---|
| Main bus voltage (V) | ELECTRICAL MAIN BUS VOLTAGE (volts) | sim/cockpit2/electrical/bus_volts[0] |
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.
