What is the speed limit for taxiways?

Taxiway Speeds: Ensuring Safety and Clearance

Taxiways are designated paths on the airport surface that allow aircraft to maneuver between the runway and their designated parking areas. To ensure the safe and efficient movement of aircraft, taxiing speeds are typically regulated, but can vary depending on airport regulations and operational factors.

General Taxiway Speed Range

In general, taxiing aircraft typically maintain speeds between 20 and 30 knots (23 and 35 miles per hour). This range provides a balance between safety considerations and the need to maintain a reasonable pace of movement.

Airport-Specific Restrictions

Some airports may impose specific speed limits on taxiways. These limits are usually posted on signage along the taxiway and are intended to further enhance safety based on the airport’s unique characteristics, such as:

• Runway proximity
• Obstruction placement
• Traffic volume

Safe Operational Clearance

The primary consideration when determining taxiway speed limits is maintaining safe operational clearance around obstacles. Aircraft must maintain a sufficient distance from other aircraft, vehicles, and ground infrastructure to avoid potential collisions or damage.

Manufacturer Guidelines

Aircraft manufacturers provide guidelines for recommended taxiing speeds based on the specific type and size of aircraft. These guidelines are derived from engineering specifications and flight tests and should be adhered to to ensure safe handling and avoid any potential mechanical issues.

Maintaining Safety

Ultimately, the speed at which aircraft taxi is determined by the pilot-in-command, who must make a judgment call based on the prevailing conditions. Factors such as visibility, weather, and traffic density should be taken into account to ensure the safety of the aircraft and all personnel on the airport surface.

By adhering to established speed limits and maintaining safe operational clearance, pilots can contribute to the safe and efficient movement of aircraft on taxiways, ensuring a smooth flow of ground traffic and minimizing the risk of incidents.
