Variants

C152 stylev1.0

This instrument; it appears in the picker as the FACE variant of Vacuum / ammeter

Picker: Vacuum / ammeter, FACE: C152 style

Features

SUCTION dial with its green band, ticks every 0.5 in Hg
AMPS dial -60 / 0 / +60 with signed numbers
Muted printed arcs; needle with shadow and glass reflection
Red X over the strip when suction or amps is missing or stale
Realistic needles (Settings): spring and 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: Suction range and green band from the profile when it has one, otherwise a default 3-7 in Hg. A generic profile (an aircraft the Hub doesn't know) gets wide default scales with no bands or red lines.

On the iPad

No knobs: a tap asks to change the instrument

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
Vacuum / suction (inHg)	`SUCTION PRESSURE (inHg)`	`sim/cockpit/misc/vacuum`
Ammeter, + charging (A)	`ELECTRICAL BATTERY LOAD:1 (amperes)`	`sim/cockpit2/electrical/battery_amps[0]`

Add-on aircraft with their own systems may use other variables; the Hub reads the standard ones.
