ABSTRACT:
In an aircraft having two engines, a pilot's master control throttle assembly for selectively operating one or both engines and configured to allow for synchronization of the engines using only the master control throttle, the master control assembly has a master throttle lever with a fixed carriage pin extending laterally therefrom which engages detents located in separate slave throttles for each engine. The detent in one slave throttle is a snug fit around the carriage pin, releasably locking it to the master throttle, while the detent in the other slave throttle is elongated, allowing for engine synchronization by movement of the carriage pin within the range of the elongated detent. The slave throttles are spring loaded and can be selectively disengaged from or engaged to the master throttle.
