“Safety concerns about wiring systems in airplanes were brought to the forefront of public attention by a midair explosion in 1996 involving a 747 airplane. Ignition of flammable vapors in the fuel tank was the probable cause of that fatal accident, and the most likely source was a wiring failure that allowed a spark to enter the fuel tank.
Aircraft electrical system schematic. The electrical system generally consist of a battery, generator or alternator , switches, circuit breakers and instruments such as voltmeters and ammeters . Back up electrical supply can be provided by a ram air turbine (RAT) or Hydrazine powered turbines.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
In the United States, the Federal Aviation Administration (FAA) issues Technical Standard Orders (TSOs) regarding equipment used on civil aircraft. The TSO for aviation headsets is C139, which includes requirements to withstand extreme heat and cold, decompression, and electromagnetic interference. [14]
A fly-by-wire (FBW) system replaces manual flight control of an aircraft with an electronic interface. The movements of flight controls are converted to electronic signals transmitted by wires (hence the term fly-by-wire), and flight control computers determine how to move the actuators at each control surface to provide the expected response ...
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
Title of the Boeing T-43A Flight Manual. An aircraft flight manual (AFM) is a paper book or electronic information set containing information required to operate an aircraft of certain type or particular aircraft of that type (each AFM is tailored for a specific aircraft, though aircraft of the same type naturally have very similar AFMs).
The Airbus A320 family was the first airliner to feature a full glass cockpit and digital fly-by-wire flight control system. The only analogue instruments were the radio magnetic indicator, brake pressure indicator, standby altimeter and artificial horizon, the latter two being replaced by a digital integrated standby instrument system in later production models.
