Airlines are doing everything they can to reduce their fuel costs. You may have taken an airline flight recently where the crew taxied to or from the runway on one engine. Â Or you’ve noticed that the Auxiliary Power Unit (APU) isn’t running when a plane is at the gate. Sometimes, if possible, instead of running the APU the plane can be plugged into “ground power,” getting it’s juice through a big extension cord from the terminal.
Airlines are also playing with new approach procedures that smooth out the descent and path to the runway, allowing crews to bring the power back to near-idle thrust and pretty well glide most of the way to the threshold and saving on fuel. The goal is to try and do anything to save fuel while keeping passengers safe.
Honeywell and Paris-based Safran Groupe have come up with some nifty new technology that could save airlines hundreds of thousands of dollars a year in fuel costs for each aircraft. It’s called the “Electric Green Taxi System” or EGTS, and it was recently demo’d at the Paris Air Show.
