Aircraft electrical symbols

The unit used to measure resistance is called the ohm. Symbols can be used to excellent advantage when needed to show the shape of an object. Typical shape symbols used on aircraft drawings are shown in Figure 2-27. The electrical and electronic symbols shown here are those that are likely to be encountered by the aviation maintenance technician.

They are in accor- dance with ANSI-Y32.

Only those symbols associated with aircraft electrical and elec- tronic wiring have been .

A variety of specialized symbols originally used for aircraft applications have been added to make this standard more .

Time Delay Starting or Closing Relay. Checking or Interlocking Relay. Voltage symbol is traditionally “E” for. Current symbol is traditionally “I” for Intensity.

Resistance symbol is “R” in equations and the. Abstract: LAST month we had occasion to comment adversely on the lack of standardization which characterizes domestic electric equipment, while congratulating the S. Power symbol may be “P”ower or “W”atts . There is one fiel however, in which the electrical . Diagrams of this type do not indicate the actual physical location of the individual components in the aircraft. The largest collection of symbols in the network.

For consultation and interpretation of components and electrical circuit. It is very important that the avia- tion mechanic who is to make or assemble the object understand the meaning of the different lines, notes, abbreviations. The term “ electrical system” as used in this AC means those parts of the aircraft that generate, distribute, and use electrical energy, including their support and attachments.

The satisfactory performance of an aircraft is dependent upon the continued re- liability of the electrical system. This job aid covers applicable CFR part aircraft (although it is also widely acceptable for use with other types of aircraft such as military, small airplanes, and rotorcraft). V symbol illuminates in the range of 9. Define terms related to basic DC electricity, including passive, active, semiconductor components, and control devices.
