Abstract: A control interface for an aircraft electric taxi system (ETS) may be incorporated in a housing positioned in a flight deck of the aircraft. The control interface may include an actuator, an electronic control sensor interconnected with the ETS to provide speed and direction signals to the ETS and an extendable shaft interposed between the actuator and the electronic control sensor. The actuator may be configured to rotate around an axis of the shaft between a first rotational position, in which the actuator is stowed within the housing, and a second rotational position in which the actuator is outside of the housing.

Abstract: A brake monitoring system comprises a wear pin that is operatively connected to a brake to be monitored, wherein the wear pin can translate along a longitudinal axis of the wear pin and not rotate about the longitudinal axis; a wear gear rotationally affixed to the wear pin to enable the wear gear to rotate as the wear pin translates; and a counting device operatively adjacent the wear gear, wherein the counting device measures one of an amount of rotation of the wear gear and a rate of rotation of the wear gear.

Abstract: Provided are a method of and apparatus for applying a chemical to an agricultural field. A current position of chemical application equipment used to apply the chemical to the field is determined. A desired application rate for a first position a distance d ahead of the current position of the chemical application equipment is determined or retrieved from a data base containing a plurality of chemical application rates for the injector channels. The chemical application equipment is controlled, while the chemical application equipment is approximately at the current position, to change the chemical application rate from a current application rate to the desired application rate if the desired application rate is within a predetermined range, and to maintain the current application rate if the desired application rate is outside of the predetermined range, and for accurately recording chemical application rate and position data.
