Taxiway Width Calculator

Taxiway Width Formula:

\[ TW = TM + 2 \times C \]

Taxiway Width (m):

Minimum Width (with tolerance):

Maximum Width (with tolerance):

1. What is a Taxiway Width Calculator?

Definition: This calculator determines the required width of an airport taxiway based on aircraft gear dimensions and clearance requirements.

Purpose: It helps airport engineers and planners design taxiways that safely accommodate aircraft movements.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ TW = TM + 2 \times C \]

Where:

\( TW \) — Taxiway Width (meters)
\( TM \) — Maximum Outer Main Gear Wheel Span (meters)
\( C \) — Clearance Distance (meters)

Explanation: The taxiway width equals the aircraft's maximum wheel span plus clearance on both sides.

3. Importance of Taxiway Width Calculation

Details: Proper taxiway width ensures safe aircraft movement, prevents wingtip collisions, and accommodates varying aircraft sizes.

4. Using the Calculator

Tips: Enter the maximum outer main gear wheel span, clearance distance, and tolerance percentage (default ±5%). All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical clearance distance?
A: Standard clearance is typically 4.5m for Code E aircraft (like Boeing 747), but varies by aircraft group.

Q2: Why include a tolerance percentage?
A: The tolerance accounts for construction variations and provides a safety margin.

Q3: How do I find the maximum wheel span?
A: Consult aircraft specifications or airport planning manuals for the largest aircraft using the taxiway.

Q4: What about taxiways for multiple aircraft?
A: Design for the largest aircraft or consider separate taxiways for different aircraft groups.

Q5: Are there regulatory requirements?
A: Yes, ICAO and FAA provide standards for taxiway widths based on aircraft classification.
