Aircraft Throttle Quadrants

Aircraft Throttle Quadrants

Our aircraft throttle quadrants are engineered expressly to solve customer and industry needs. Kawak quadrants utilize a positive engaging lever gate design ensuring maximal safety on the ground and in the air. To ensure lasting functionality and smooth operation, the highest quality materials, processes, and finishes are used in each quadrant we produce.

Kawak’s aircraft throttle quadrants are a compilation of all the experience and feedback we’ve gained since our first turbine engine conversion in 1994. Our first aircraft throttle quadrants were designed for our Thrush and Dromader aircraft conversions, and we now produce product lines for many aircraft types which require controls for Power, Propeller, and Condition functions.

Along with PMA approved quadrants Kawak also continues to develop single and twin engine aircraft throttle quadrants for applications where high quality, spacial accommodation, and guaranteed functionality are requirements. When designing new throttle quadrant variations Kawak works closely with our customers to ensure all design and regulatory requirements are met to achieve the desired product outcome.
