CDU & EGI Power and Navigation Control Panel
Loading...
Right console, mid-lower section — situated below the CDU keypad and adjacent to the Environmental Control panel.
Controls power supply to the CDU (Control Display Unit) and EGI (Embedded GPS/INS), and allows pilot input for navigation mode selection and steerpoint/page management. This panel is critical for flight navigation initialization and waypoint management.
Power Section
CDU Power Switch (ON/OFF)
Activates power to the Control Display Unit.
When ON, enables CDU screen and interface for mission data management.
EGI Power Switch (ON/OFF)
Powers the Embedded GPS/INS (primary navigation system).
EGI integrates GPS with inertial reference data to provide position and attitude information to onboard systems.
Navigation Section
STEER PT Knob (Rotary Selector)
RT PLAN – Route plan editing or selection.
MARK – Selects markpoints created in-flight.
MISSION – Activates mission flight plan points.
PAGE Knob (Rotary Selector)
POSITION – Displays current aircraft position.
STEER – Focuses on current steering waypoint.
WAYPT – Allows waypoint review or editing.
OTHER – Access to miscellaneous navigation pages.
STEER Button (Momentary Push)
Cycles through steerpoints or confirms selection.
Recommended Hardware (simpit build)
2 × Toggle switches (ON/OFF) for CDU and EGI power.
2 × Rotary switches (3–4 positions) for STEER PT and PAGE selection (3P4T rotary or mechanical encoder if interfaced via Arduino).
1 × Momentary push button for STEER function.
Optional: Add LED indicators for CDU and EGI power states.
Panel material: 3 mm matte black acrylic, white engraved text.
Knobs: Standard 18–20 mm diameter rotaries (can reuse same profile as other A-10C knobs).
Mounting depth: 20 mm minimum behind faceplate for rotary clearance.
Backlighting: Optional edge-lit green LEDs or diffuse panel backlight.

Real Aircraft Notes
The CDU/EGI system initializes the A-10C’s navigation and targeting database. During startup, the pilot powers both systems, aligns the EGI, and uses the CDU panel to confirm INS alignment before flight.
