Improving apron air quality with aircraft ground energy systems at Zurich Airport

摘要

The operation of aircraft auxiliary power units (APU) during ground time at airports causes emissions and noise and is not highly efficient. Instead, aircraft ground energy systems (AGES) provide technically feasible, economic viable and environmentally beneficial alternatives for providingelectricity and preconditioned air to aircraft. This paper describes Zurich Airport's adopting a concept to install AGES for electricity and preconditioned air at all pier stands and fixed electrical system on open stands. The combination of a high technical serviceability, enforcedlocal regulations and an attractive charging scheme has led to significant reductions of local and global emissions while providing cost savings to airlines.
