Formula Used
This calculator uses a practical planning method for preliminary taxiway sizing.
The reference width acts like a governing minimum. The gear-based width checks whether aircraft geometry and edge clearance demand a larger pavement width.
How to Use This Calculator
- Choose metric or imperial units.
- Enter a design aircraft name for your report.
- Select a preset reference width, or type your own override.
- Enter main gear span and edge clearance per side.
- Add shoulders, curve widening, and extra safety margin.
- Enter segment length and pavement layer thicknesses.
- Press the calculate button.
- Review the result, graph, and export buttons above the form.
Example Data Table
| Scenario | Reference Width (m) | Main Gear Span (m) | Edge Clearance Each Side (m) | Curve Widening (%) | Safety Margin (%) | Recommended Pavement Width (m) | Overall Width With Shoulders (m) |
|---|---|---|---|---|---|---|---|

FAQs
1) What does this calculator estimate?
It estimates recommended taxiway pavement width, overall width with shoulders, pavement area, and material volumes for a selected segment length.
2) Why does the tool use both reference width and gear-based width?
The larger value controls the design check. This lets you compare a governing minimum against aircraft geometry and edge clearance needs.
3) Does this replace airport design standards?
No. It supports planning, comparison, and cost checks. Final taxiway dimensions must follow the governing standard, project criteria, and qualified engineering review.
4) When should curve widening be added?
Use it when the taxiway includes bends, exits, or geometry that requires extra operating margin beyond the straight-run controlling width.
5) What is shoulder width used for?
Shoulders increase the total developed width beside the paved strip. They improve edge support, drainage coordination, and operational recovery space.
6) Why calculate pavement and base volumes?
Construction teams need quantity estimates for budgeting, haulage, production planning, and material procurement during early-stage project development.
7) Can I use feet instead of meters?
Yes. Switch the unit system to imperial. The calculator converts inputs internally and returns lengths, areas, and volumes in matching imperial units.
8) What is the best way to compare design options?
Run multiple scenarios by changing clearances, shoulders, or curve percentages. Then export each result to CSV or PDF for side-by-side review.
