Single lever control system for engines with multiple control modes

Abstract:

An engine control system includes a first user control lever configured for rotational movement between a first control position and a second control position and a second user control lever configured for rotational movement between a third control position and a fourth control position. The first user control lever is configured for operational control of an engine in a first control mode and the second user control lever is configured for operational control of the engine in a second control mode, such as a backup mode. A mechanical link couples the first user control lever to the second user control lever with at least one angular offset. As a result of the angular offset, the second user control lever can be maintained in a safe operating position relative to the first user control lever position.
