Patent Images
1. An aircraft control system comprising:
- a control input;
an effector module connected to said control input, said effector module including at least one microprocessor, and having at least a primary control module output, a primary control module input, and a controlled device output;
a primary control module connected to said primary control module output of said effector module and said primary control module input of said effector module, said primary control module including at least one microprocessor; and
wherein said at least one microprocessor in said effector module provides a backup control path bypassing said primary control module when said primary control module is in a failed state.

Abstract
An aircraft control system includes an effector module connected to a control input and a primary control module connected to the effector module. A microprocessor in the effector module provides a backup control path bypassing the primary control module when the primary control module is in a failed state.

12. A method of controlling an aircraft system comprising the steps of:
-
receiving a pilot or autopilot input command at an effector module; determining a movement instruction for a controlled aircraft component based on said pilot input command and at least flight critical sensor information in a microprocessor of said effector module when a primary control module is in a failed state; and outputting said movement instruction to said controlled aircraft component, thereby controlling said controlled aircraft component. - View Dependent Claims (13, 14, 22)
