The concept of utilizing an electrically actuated aircraft braking system could result in greater fire safety, the elimination of centralized hydraulics, and compatibility with an all-electric aircraft. Using the Air Force A-10 as a test bed, the first fully functional electric brake was laboratory tested, qualified, and installed on an aircraft for testing. On-aircraft testing was curtailed due to a dynamic instability between the brake and landing gear. An extensive laboratory dynamometer test program was substituted. The prototype electric brake demonstrated performance nearly equivalent to the production hydraulic brake with a potential for more accurate torque control.
