Routledge. For this reason, most fly-by-wire systems incorporate either redundant computers (triplex, quadruplex etc.), some kind of mechanical or hydraulic backup or a combination of both. The fly-by-wire computers act to stabilize the aircraft and adjust the flying characteristics without the pilot's involvement, and to prevent the pilot from operating outside of the aircraft's safe performance envelope. I should note that actually did a test on the RV-10 I'm flying. Pre-flight safety checks of a fly-by-wire system are often performed using built-in test equipment (BITE). In 1941, Karl Otto Altvater, who was an engineer at Siemens, developed and tested the first fly-by-wire system for the Heinkel He 111, in which the aircraft was fully controlled by electronic impulses.

Some aircraft, the Panavia Tornado for example, retain a very basic hydro-mechanical backup system for limited flight control capability on losing electrical power; in the case of the Tornado this allows rudimentary control of the stabilators only for pitch and roll axis movements. The flight control computer then calculates what control surface movements will cause the plane to perform that action and issues those commands to the electronic controllers for each surface. The controllers at each surface receive these commands and then move actuators attached to the control surface until it has moved to where the flight control computer commanded it to. To be able to view a digitally modulated channel, home, or customer-premises equipment (CPE), e.g. digital televisions, computers, or set-top boxes, are required to convert the RF signals to signals that are compatible with display devices such as analog televisions or computer monitors. Lighting and general purpose receptacles are at 120 volts AC, with larger devices fed by three wire single-phase circuits at 240 volts. Most GFCI receptacles allow the connection and provide GFCI protection for down-stream connected receptacles. Bi-directional communication allows each device to receive data as well as transmit it. These new data transmission requirements may require new transmission means other than the present overcrowded radio spectrum.

The pilot may not be fully aware of all the control outputs acting to affect the outcome, only that the aircraft is reacting as expected. This modifies the manual inputs of the pilot in accordance with control parameters. Improved fully fly-by-wire systems interpret the pilot's control inputs as a desired outcome and calculate the control surface positions required to achieve that outcome; this results in various combinations of rudder, elevator, aileron, flaps and engine controls in different situations using a closed feedback loop. The advantages of FBW controls were first exploited by the military and then in the commercial airline market. High performance aircraft that have fly-by-wire controls (also called CCVs or Control-Configured Vehicles) may be deliberately designed to have low or even negative stability in some flight regimes - rapid-reacting CCV controls can electronically stabilize the lack of natural stability. Equipment for one-way systems may use POTS or radio networks to communicate to the headend. It may also send a parity bit. Since the 11 (or 29 for CAN 2.0B) bit identifier is transmitted by all nodes at the start of the CAN frame, the node with the lowest identifier transmits more zeros at the start of the frame, and that is the node that wins the arbitration or has the highest priority.

The overload frame contains the two bit fields: Overload Flag and Overload Delimiter. To prevent interference of signals, the frequency band is divided into two sections. Services on these systems are carried on RF signals in the 5 MHz to 1000 MHz frequency band. In telecommunications, a broadband signalling method is one that handles a wide band of frequencies. The original method to transport video over the HFC network and, still the most widely used method, is by modulation of standard analog TV channels which is similar to the method used for transmission of over-the-air broadcast. The forward-path or downstream signals carry information from the headend/hub office to the home, such as video content, voice and Internet traffic. Traditionally, since video content was sent only to the home, the HFC network was structured to be asymmetrical: one direction has much more data-carrying capacity than the other direction. Since references to Mini ATX have been removed from ATX specifications since the adoption of microATX, the AOpen definition is the more contemporary term and the one listed above is apparently only of historical significance.
