Oxygen Regulator Panel
Loading...
Right console, mid-section — mounted to the right of the CDU, directly above the Environmental Control Panel.
Controls the pilot’s oxygen delivery system, regulating pressure, flow rate, and oxygen concentration during flight. This system ensures proper oxygen supply at varying altitudes and allows emergency override or test functions when needed.
FLOW Indicator (Mechanical or Electronic) — Displays oxygen flow activity during breathing; oscillates with inhalation and exhalation.
Flow Adjustment Knob (+ / –) — Adjusts the oxygen flow rate in pressure-demand mode.
EMERGENCY: Supplies 100% oxygen at positive pressure for smoke or contamination conditions.
NORMAL: Provides automatic oxygen delivery based on cabin altitude.
TEST MASK: Verifies oxygen flow through the pilot’s mask during pre-flight checks.
OFF: Shuts off oxygen flow to the mask.
NORMAL OXYGEN: Standard operation, mixes oxygen with cabin air as needed.
100% OXYGEN: Forces 100% oxygen regardless of altitude.
Displays system supply pressure in PSI.
Normal reading: ~70–120 PSI when system active.
Recommended hardware (simpit)
2 × 3-position toggle switches (ON-ON-ON) for SUPPLY and EMERGENCY/NORMAL/TEST MASK controls.
1 × Rotary potentiometer (10kΩ) for flow adjustment simulation.
1 × Analog gauge (servo-driven or LED bar) for supply pressure simulation.
Optional LED indicator to represent oxygen flow activity.
Panel thickness: 3 mm matte acrylic, engraved white lettering.
Knobs: Custom 3D printed or aluminum, 15–18 mm diameter.
Lighting: Dim green or white backlighting via edge-lit acrylic or micro-LEDs.
Notes (DCS-BIOS) Bindings for full simulation include:
OXY_SUPPLY_LEVER
OXY_MODE_SWITCH
OXY_PRESS_GAUGE
OXY_FLOW_INDICATOR
This allows realistic synchronization of oxygen pressure readings, lever positions, and switch states.
The A-10C uses a diluter-demand oxygen system, automatically adjusting oxygen mix based on cabin altitude, with pressure-demand override for emergency use.
