Materials with tightly bound electrons are poor conductors or good insulators

They are poor conductors

Materials with large numbers of free electrons are good conductors or poor conductors

Good conductors

Good conductors include …

1. Copper

2. Aluminium

3. Gold

4. Silver

Poor conductors include ….

1. Plastic

2. Rubber

3. Wood

4. Very dry air

Static electricity is …

Is an accumulation of electrical charge in an object. Charge can accumulate on well insulated objects

Purpose of static discharge wicks are to …

Ease the flow of charge from the airframe ( aircraft ) into the atmosphere

What properties does static discharge wicks have

1. Are flexible

2. Very good conductive properties

3. Attached at the trailing edge of the aircraft

When must you inspect the static wick on an aircraft

Before very flight to ensure they are present

To ensure there is no potential difference between one part and another all parts of the airframe must be …

Electrically bonded together

Poor electrical binding may cause

1. Electrical equipment to fail

2. Excessive interference on the radios

Does static wicks discharge all charge

No, a large electrical potential difference between the aircraft and ground may be present after landing

A well bonded airframe can be used as …

A common earth return for all electrical components
