In one embodiment, a method for controlling an aircraft comprises providing an attitude error as a first input into a neural controller and an attitude rate as a second input into the neural controller. The projected connection terminal of the lens unit is arranged on the connection pad of the wiring substrate, and the connection pad and the projected connection terminal are joined mutually by a conductive adhesive agent. Such methods also allow for reduced energy use in the production and drying of spent fermentation broth due to increased effective concentration of the alcohol product by the simultaneous fermentation and recovery process which increases the quantity of alcohol produced and recovered per quantity of fermentation broth dried.
