According to the operator Royal Schiphol Group, Schiphol Airport in Amsterdam aims to purchase two TaxiBots to transport planes from the gate to the runway rather than utilizing their own jet power. It is part of the airport’s endeavor to minimize emissions and make operations more environmentally friendly.
Trials using a special airplane towing vehicle have been placed at airports in Delhi and Bangalore, India. Lufthansa, meanwhile, tried a TaxiBot seven years ago. However, Schiphol is the world’s first airport to want to implement sustainable taxiing on a large scale.
The TaxiBot is a semi-robotic hybrid towing vehicle manufactured by Smart Airport Systems under license from Israel Aircraft Industries for taxiing planes with their engines turned off. The system is based on a vehicle that links to the airplane and is piloted. According to the corporation, the unique towing trucks may lower fuel consumption and noxious emissions, including CO2, by up to 85 percent, and noise pollution by up to 60 percent. It also increases efficiency by decreasing lost time at the gate during engine start-up, resulting in faster aircraft turn times.
A recent trial at Schiphol Airport demonstrated that sustainable taxiing results in 50% less fuel use during taxiing, cutting CO2, nitrogen oxides, and ultrafine particle emissions. Given the distance involved, fuel savings might reach up to 65 percent when aircraft taxi to Schiphol’s runway, according to the airport operator.
One way airports and airlines are attempting to lessen the environmental impact of ground operations is through the use of autonomous towing trucks. Others include self-driving luggage carts and buses.
Schiphol Airport, in collaboration with Air Traffic Control the Netherlands, KLM, Transavia, and Corendon Dutch Airlines, as well as ground handling companies dnata and KLM Ground Services, has devised a step-by-step plan to make sustainable taxiing normal procedure at Schiphol by 2030. The strategy is part of a larger European push to develop and demonstrate more sustainable flight operations from gate to gate, utilizing diverse tactics and solutions to conserve fuel at each stage of a trip.
The two TaxiBots will be deployed in a follow-up pilot program by mid-year as the first step in the strategy. If the pilot phase is successful, it will become the usual operating procedure, and the number of aircraft that taxi to and from the runway with a tow will progressively increase. Officials anticipate that after four years, 18 percent of all flights will taxi sustainably, with the practice spreading to more runways by 2025.
The airport’s operator, Royal Schiphol Group, recently announced infrastructure changes to facilitate sustainable taxiing to and from the runway. The project includes marks on the asphalt to ensure that the airplane stops in the proper location and can be removed from the tow truck. Roads must also be expanded so that special trucks may drive back and forth once an aircraft has been released without interfering with other aircraft traffic.
Meanwhile, Smart Airport Systems is working on a zero-emission car that will run on either electricity or hydrogen.
