An air data sensor probe for providing measurements of total pressure, static pressure and angle-of-attack for an aircraft in flight. The probe is essentially cylindrical with a hemispherical nose. It has a vertically elongated central opening for measurement of total pressure and a plurality of off-axis openings, manifolded by pairs, to measure angle-of-attack. Static pressure is measured by a plurality of ports mounted back from the nose, manifolded together to provide the static pressure reading.

Combination alpha, static and total pressure probe

A mechanical variable authority trim mixer for controlling the flow of fuel to an engine receives a main input from the throttle lever and a second input from a trim actuator motor. The trim mixer combines the inputs to produce a single output operably connected to the fuel metering control of the engine. A programmed cam modifies or neutralizes the effects of the trim input through selected ranges of the main throttle input stroke.
