Engine Electrical Sysem Flashcards
What are two ways wires can be attached to the pins in a Canon plug
Soldering wires into pins and sockets
Crimping pins into tapered holes in pins and sockets
Why is stranded wire rather than solid wire used in most power plant electrical systems
Solid wire is likely to break when it is subjected to vibration
What two things must be considered in selection of wire when making an electrical install installation in an aircraft
The current caring capability of the wire and the voltage drop caused by current flowing through the wire
What is used to protect a wire bundle from chafing where it passes through a hole in the bulkhead or frame?
And Gromit around the edges of the hole
How are electrical wires protected where they pass through an area of high temperature
Wire passes through these areas are insulated with high temperature insulation and the wire are enclosed in some type of protective conduit
What is the minimum separation allowed between a wire bundle and a fluid line that carries combustible fluid or oxygen?
6 inches inches whenever possible if not, the wire should not run parallel to the fuel or oxygen line and minimum of 2 inches must be maintained
Which aircraft electrical circuit does not normally contain a fuse or circuit breaker
The starter motor circuit
When should aircraft wiring be installed in a conduit?
When the wiring passes through an area in the aircraft where wiring could likely be damaged such as a wheelwell
What is meant by a trip free circuit breaker
A circuit breaker that opens a circuit anytime an excessive amount of current flows, regardless of the position of the circuit breakers operating here
Which way should the toggle of a switch that controls? The propeller pitch moved to place the propeller in low pitch high RPM
Forward
Why are protective covers placed over some switches in an electrical circuit?
To prevent the switch from being advertently actuated
