Final answer:
To statically discharge a windscreen, one must thoroughly rub the object with a dry cloth, open the faucet to create a smooth water filament, and then move the charged object towards the water to discharge the static.
Step-by-step explanation:
Prior to statically discharging the windscreen, or any plastic object, certain steps should be taken to ensure a safe and effective process. The procedure involves the following steps:
- Thoroughly rub the plastic object with a dry cloth to increase the static charge.
- Open the faucet just enough to allow a smooth filament of water to flow, which will be used in the discharging process.
- Bring an edge of the charged plastic object close to the filament of running water, which will help in dissolving the static charge.
These steps ensure that the static electricity is safely dissipated without causing damage or sparking, which is important in environments such as aircraft maintenance where static discharge can be hazardous.
