Abstract: A deceleration feedback algorithm for an aircraft braking system is provided. The algorithm prevents the aircraft brakes for releasing to clearance during a braking operation, while maintaining differential pilot/co-pilot braking inputs. The method and system determine an actual rate of deceleration of the aircraft and calculate the required rate of deceleration of the aircraft, thereafter making a comparison of the actual and required rates of deceleration. It then controls the application and release of brake pressure to the right and left brakes of the aircraft as a function of that comparison, while precluding the discs of the heat stacks from going into separation as a consequence of non-braking activities. Additionally, a minimum brake pressure is provided, ensuring the capability of differential braking between the right and left brake pedals and associated right and left brakes.

Abstract: The present application relates to the field of metal detectors, which may find military, industrial and civilian application. In one form, the present application relates to a method and apparatus for a metal detection system in which a first component is synchronized with a second component. The metal detection system is adapted for use in diminishing interference between two or more metal detectors operating in close proximity. In one form, the metal detection system is adapted for use in a ground loop metal detection system that allows for the detection of metal or metallic objects at greater depths than currently available with standard pulse induction or induction type metal detecting equipment.

Abstract: A braking system (1) for an aircraft which includes a by-pass control system (9) for activation when undemanded braking or loss of braking is detected.

Abstract: An electrically actuated aircraft brake with a carbon-carbon composite heat pack and an electrical actuator for engaging the heat pack and operating the brake. When the brake is not being applied, the brake actuator is adjusted in dependence upon temperature, for example, by controlling the actuator to maintain a temperature regulated position.

Abstract: Method and apparatus for monitoring electrically-actuated aircraft brakes includes measuring the break heat pack thickness to determine wear of the brake discs and adjusting the measurement so as to give ongoing compensation for temperature variations and hence expansion of the heat pack.
