Module 6 is on materials and hardware. The topic number 11 is about electrical cables and connectors. Among the subjects covered are...
a. Cables types, construction and characteristics
b. High tension and coaxial cable
c. Connectors types, plugs and receptacles, pins and sockets, identification codes, couplings
d. insulators
e. Current rating
The term cable and wires are used interchangeably to mean the electrical wires.
On completion of the course, I normally gave some quiz. These are the example of the close book quiz...
1. What is/are the characteristics of airframe cable?
2. Why the wire in bundle and protective conduit carries less current compared to the cable in free air?
3. what is the method used to reduce intercable interference in a ribbon cable.
4. What is the different between fire resistance and fire proof cables?.
5. What is the material commonly used a the screen in "screened" cable?
6. What is the range of AWG size of cable used in an aircraft?
7. Name 3 disadvantage of aluminium wires and how does it effect its installation.
8. Silver plating has 2 disadvantages, what are thy?
9. Name the plating used for general aircraft wiring and the high temp cable.
10. PVC is a good insulator, but it has disadvantage, what is it?
The DCAM and EASA had set the number of questions for module 6, inclusive of part 11. It is give in the AN1101 appendix 2.
