Flight control system and method of use

A method of using a flight control system to operate a flight control surface, said method comprising:

• receiving, at a first remote electronics unit (REU), a first control signal, from a first actuator control electronics (ACE), for operating an actuator coupled to the flight control surface;
• receiving, at a second REU, a second control signal, from a second ACE, for operating the actuator;
• transmitting the second control signal from the second REU to the first REU;
• and
• operating, by the first REU, the actuator based on the first control signal and the second control signal.

A flight control system for a horizontal stabilizer, said flight control system comprising:

• an actuator coupled to the horizontal stabilizer;
• a first remote electronics unit (REU) coupled to said actuator and configured to operate said actuator based on respective control signals originating from at least two actuator control electronics (ACE);
• and
• a second REU coupled to said actuator and configured to operate said actuator, independent of said first REU, based on respective control signals originating from at least two ACE, said second REU further coupled to said first REU and further configured to transmit a control signal, received from an ACE, to said first REU.
