Dimensions & Schematics
Measured dimensions, reference schematics, and Fusion 360 design files for the Boeing 737 MAX cockpit panels.
Measurement Methodology
All dimensions are derived from a combination of:
- Boeing Technical Training Manuals — structural references where available
- Scaled photography — using known objects (standard avionics connectors, 1-inch annunciators) as size references
- Community cross-referencing — dimensions validated against multiple cockpit photos and builder reports
- Physical mockups — critical dimensions tested with cardboard templates before cutting MDF
All measurements below are in millimetres unless stated.
Disclaimer: These are builder-derived measurements for home simulator use. They should not be used for any certified aviation purpose.
Mode Control Panel (MCP)
Overall Panel Dimensions
| Dimension | Value |
|---|---|
| Total width | 940 mm |
| Height | 132 mm |
| Depth (including housing) | 78 mm |
| Panel substrate thickness | 3 mm |
| Acrylic overlay thickness | 3 mm |
Switch Cutout Dimensions
| Switch Type | Cutout W | Cutout H | Notes |
|---|---|---|---|
| Taiway toggle (standard) | 9.5 mm | 12.5 mm | Standard MIL-SPEC toggle footprint |
| Bourns encoder (PEC11R) | 7 mm dia. | — | Round cutout, tighten with included nut |
| Annunciator (1×1 inch) | 25.4 mm | 25.4 mm | Standard 1-inch annunciator |
| 7-segment display (TM1637 4-digit) | 72 mm | 18 mm | Verify against specific module |
Encoder Knob Spacing (MCP)
Encoder centre-to-centre spacings on the MCP, measured left to right:
[CRS L] [SPD] [HDG] [ALT] [V/S] [CRS R]

Glare Shield
Structure
| Dimension | Value |
|---|---|
| Total width | 970 mm |
| Height (front face) | 210 mm |
| Depth (top rail to rear) | 180 mm |
| Angle of front face | 15° reclined |
| Material | 6mm MDF (structure) + 3mm MDF (face) |
The glare shield is built as a box frame from 6mm MDF, with the face panel inset and bonded with wood glue and M4 bolts. The EFIS selector panels (Captain and First Officer) are mounted on recessed pockets on each side.
EFIS Selector Panel
| Dimension | Value |
|---|---|
| Panel width | 140 mm |
| Panel height | 95 mm |
| Encoder spacing (left to right) | 35 mm |
| Number of encoders | 3 per side |
| Number of selectors (VOR/ADF) | 2 per side |
Overhead Panel (OHP)
The overhead panel is the most complex assembly — over 200 switches and annunciators across 8 zones.
Panel Dimensions
| Dimension | Value |
|---|---|
| Total width | 800 mm |
| Total height | 460 mm |
| Mounting angle | 10° inclined toward pilot |
| Material | 3mm MDF panels, 25mm MDF frame |

Center Pedestal
Throttle Quadrant
| Dimension | Value |
|---|---|
| Overall width | 220 mm |
| Overall depth | 380 mm |
| Throttle lever throw | 110 mm |
| Flap lever travel | 68 mm |
| Number of throttle levers | 2 |
The throttle levers are driven by 3D-printed PETG bodies with internal brass bushings, mounted on 8mm stainless shafts. Detents at IDLE, CLB, and MCT are implemented with spring-loaded ball bearings pressing into machined notches.
3D Printed Parts
| Part | Material | Print Time | Infill |
|---|---|---|---|
| Encoder knobs (per unit) | PETG, Black | 45 min | 30% |
| Throttle lever body | PETG, Black | 3h 20min | 40% |
| Annunciator housing (1×1") | PETG, White | 25 min | 20% |
| Switch guard (protective flip) | PETG, Red/Black | 15 min | 20% |
| Cable management clips | PETG, Black | 10 min | 15% |
