There are hundreds of busy US airports and hence tens of thousands of GSE vehicles working around the clock to turn aircraft around. GSEs are owned by the airlines and are an expense item they would rather not have. Unlike the aircraft they service, they don't generate any direct revenue. How do the airlines cut their expenses and carbon footprint on GSE?
As is normal, there is no silver bullet to save fuel at the airport gates/apron (the area near the gate), just the obvious:
- Proper equipment maintenance
- Reduce idling of all equipment when standing by
- Switch to renewable energy sources, mainly electricity. Conversion of existing equipment to electricity makes abundent sense because these vehicle barely ever stray from the gate area. They can frequently recharge. No start-up emissions to get things warmed up. No extras noise. Electric vehicles are very efficient internally relative to even a diesel engine and electric motors have high torque at low speeds. GSE vehicles are normally used until their wheels fall off. Something tells me there will be faster replacement as fuel prices remain high.
