The device that generates the reverse signal from the thrust lever angle (TLA) used to deploy reversers is the Spoiler Elevator Computer (SEC).

• A. LGCIU
• B. Thrust lever angle sensor
• C. Spoiler Elevator Computer (SEC)
• D. Hydraulic pump

Answer: (C)

The Spoiler Elevator Computer handles thrust reverser logic and is the unit that turns the pilot’s thrust lever position into a command to deploy the reversers. It continuously monitors the thrust lever angle as an input and, when conditions allow, generates the reverse signal that drives the reverser actuators. The thrust lever angle sensor simply provides the lever position; it does not generate commands. The LGCIU handles landing gear logic, not reverser control, and the hydraulic pump provides power to actuators rather than issuing the deployment command.
