The most common secondary controls are 'trim tabs' which keep the aircraft at a desired altitude by making small adjustments to the ailerons and rudder without the need for the pilot to make constant primary control adjustments. All trimming surfaces are electrically operated and controlled from the cockpit. The control and feedback signals are from position sensors and are usually high specification 'contactless' LVDT (Linear Variable Differential Transformer) or RVDT (Rotary Variable Differential Transformer) types. Trim controls are common on large aircraft, as are slats, spoilers and air brakes, which are all designed to provide finer flight control. Large aircraft also have wing flaps that alter the shape of the wing to improve flight control at lower speeds during take-off and landing.
Active Sensors design and manufacture LVDT and RVDT sensors for primary and secondary flight control electro-hydraulic actuators, engine control valves, brake-by-wire systems and much more... We meet customers system development needs by offering a complete sensor design and delivery service for fixed and rotary wing aircraft.
