Bombardier Aerospace today said it flew a Global 5000 testbed with an all-electric braking system, which the Canadian company claims is a civil aviation first. The testing lasted more than seven hours and included five landings and a series of high-speed braked ground runs. The demonstrator aircraft was equipped with Meggitt’s EBrake electric braking system and Messier-Dowty’s landing gear with electric brake wiring harnesses. According to a spokesman, the electronic braking system is being tested for the new C Series regional jet, “not for the Global 5000 or other Bombardier business jets”–at least at this time. “We tested the EBrake system’s normal, emergency and park braking functionality during both ground and flight tests. It provided improved braking control in normal and emergency operating modes, resulting in tight centerline control even during maximum brake applications,” said test pilot Gary Bruce. The Meggitt EBrake system includes electro-mechanically actuated brakes, brake data concentrators, electric motion actuation control units and supporting aircraft wiring and power distribution system. Meggitt said electrically actuated brakes will provide improved signal response, enhancing braking and anti-skid efficiency, as well as higher dispatch reliability.
