WheelTug is planned to enter service Q4 2013 Usually WheelTug weighs no more than the taxi-in fuel not needed to be loaded. A 737NG or A320 APU has sufficient spare capacity to power the system. Regular engines are seriously inefficient on the ground. The savings have been carefully researched by the company & numerous 3rd parties. It even improves the efficiency in flight (typically 0.5%): Over a period of time, engines suffer taxi FOD damage which is more prevalent on aprons (plus FOD damage from grit which blends the blades). Brake wear (especially on cold carbon brakes) is reduced. Many engines have 'power by the hour' contracts so running them less is another saving. Some airplanes that operate out of busy airports on short routes actually operate their engines longer on the ground than in the air! Using WheelTug, the operating day can be lengthened at airports that operate a noise curfew. A WT plane can be in the air 5 minutes after engine warm-up commencement. The average savings per flight will be more than the average profit per flight (Recent Wall Street Journal Report)! of 2 weeks ago's tests in Prague. There are other WheelTug videos on YouTube. The full version will be ready for Farnborough.
