GreenTaxi Project


GreenTaxi Banner

GreenTaxi™ is an L-3 strategic business development project involving technology transfer from military to commercial applications.

GreenTaxi™ is an electric or “engine off” taxi system developed by L-3 Communications for single aisle aircraft.  Phoenix Aerospace developed the strategic business plan, conducted market validation, product marketing (complete development of the package), development of complex Economic Analysis Models and simulations, assessments of operational barriers to entry and finding strategic partners to create a marketable product.  We formed a world-class team of L-3, Lufthansa Technik, Airbus, and FRAPORT to develop, test, demonstrate and validate this untapped multi-billion dollar market requirement.  We also provided Systems Engineering and Project Management expertise and the system was successfully tested and implemented on a Lufthansa Airbus A320 in December 2011.

GreenTaxi™ utilizes APU energy to drive powerful permanent magnet high-torque motors in the main landing gear wheels to allow pilots to perform gate and taxi operations without using tug equipment or the airplane main engines. This allows for reduction in fuel and emissions, elimination of tugs, increased brake life and reduction in block time and foreign object damage. The savings can be substantial, approximately $100-$330K annually per aircraft depending on the airline’s particular operation.
