An aircraft engine starting system may comprise a starter motor, a start controller for controlling the starter motor to operate with a desired torque output, and a processor for determining torque profiles for the starter motor. The processor may provide an initial torque profile responsively to ambient condition of the engine. The processor may also provide modifications to the initial torque profile responsively to temperature of the start controller.

Control methodology for an AC starter-generator system

A thermal mass flow sensor is disclosed that includes a housing () having a first sensor region and a second sensor region, a first thin film temperature sensor () formed at the first sensor region and a second thin film temperature sensor () formed at the second sensor region. A heating element () is arranged to heat the first temperature sensor () and a controller () is operably connected to the first temperature sensor (), the second temperature sensor () and the heating element (), and controls a power level to the heating element () to maintaining a temperature difference between the first temperature sensor () and the second temperature sensor (). A thin film temperature sensor and a method of using the thermal mass flow sensor are also disclosed.
