electric bonding and screening

#1. Why are static wick dischargers fitted to aircraft:

• Ato smooth the generator output.
• Bto prevent tyres bursting on landing.
• Cto minimise radio interference.
• Dto act as an earth return in a single pole electrical system.

#2. Bonding is used to protect the aircraft against fire from arcing of static electricity by:

• Aproviding an earth return.
• Bshortening the negative strips.
• Cmaintaining different electrical potential throughout the structure.
• Densuring the same electrical potential of all metal components.

#3. Static electricity constitutes a fire hazard because:

• Ametal components become very hot and ignite inflammable gases and materials.
• Bsparks occur due to differences of potential and could ignite inflammable gases and materials.
• Cof colour charged electrons.
• Daircraft tyres become heavily charged and may burst on landing.
