1. An aircraft control architecture comprising:
a triplex sensor configured to output three signals;
a first channel configured to receive a first signal of the three output signals, the first channel comprising a first processor and output a first control signal;
a second channel configured to receive a second signal of the three output signals, the second channel comprising a second processor and output a second control signal;
a remote interface device configured to receive a third signal of the three output signals; and
an effector configured to receive the first control signal and the second control signal and configured to perform an action in response to the first control signal and the second control signal,
wherein an output from the remote interface device is transmitted to each of the first channel and the second channel,
wherein an output from the first channel is received at the second channel and an output from the second channel is received at the first channel,
wherein the first control signal is based on the first signal, the output from the remote interface device, and the output from the second channel, and
wherein the second control signal is based on the second signal, the output from the remote interface device, and the output from the first channel.
