M7.7 Flashcards
1
Q
Wiring checks normally include?
A
- visual inspection
- continuity testing
- insulation resistance testing.
- Bonding testing
2
Q
What is continuity testing?
A
- Condition of being uninterrupted
- multi-meter used
3
Q
What is insulation testing?
A
- check against set criteria
- electrical resistance of an insulator separating conductors from each other and the airframe
- carried out after visual checks, bonding, and continuity checks
4
Q
What is bonding?
A
- ensures all components fitted in part of a system have the same potential resistance to ground (can be provided by local earthing point)
- prevents radio interference and induced noise at the same time
- protects systems against a build up of static charges
- reduced possibility of electrical shocks
5
Q
What are the 3 main types of bonding?
A
- equipment bonding
- metallic bonding
- static bonds
6
Q
What are the advantages of using crimps?
A
- good conductivity
- uniformity of operation
- strength of connection
- corrosion proof
7
Q
2 basic contact retention used in plug and socket connectors?
A
- Front release
- Rear release
8
Q
What are the 2 types of coaxial connections?
A
- bayonet nut
- threaded nut
