Green Taxiing

Definition of Green Taxiing

Green Taxiing refers to technologies and procedures that reduce or eliminate the use of main aircraft engines during ground taxiing. This lowers fuel consumption, cuts CO₂ and NOx emissions, and minimizes noise.

Technologies Include:

• Electric Taxiing Systems – On-board electric landing gear drives.
• Hybrid & Electric Tugs – Towbarless tractors powered by batteries or hybrid systems.
• Optimized Taxiing Procedures – Single-engine taxi, shortened taxi routes.

Benefits:

• Reduced operational costs and engine wear.
• Lower environmental impact, supporting Airport Carbon Accreditation.
• Improved air quality around terminals and aprons.

CAST Application

Using CAST Aircraft and Ground Vehicle Simulation, airports can test various taxiing concepts – from on-board electric systems to autonomous tugs – and measure their impact on turnaround times, fuel burn, and emissions. CAST enables planners to identify the optimal green taxiing strategy for their infrastructure, fleet mix, and traffic patterns.
