Results

to smooth the generator output.

to prevent tyres bursting on landing.

to minimise radio interference.

to act as an earth return in a single pole electrical system.

providing an earth return.

shortening the negative strips.

maintaining different electrical potential throughout the structure.

ensuring the same electrical potential of all metal components.

metal components become very hot and ignite inflammable gases and materials.

sparks occur due to differences of potential and could ignite inflammable gases and materials.

of colour charged electrons.

aircraft tyres become heavily charged and may burst on landing.

anodising

bond the circuit to reduce risk of fire.

prevent them discharging.

prevent short circuits in radio equipment.

prevent them interfering with the function of radio equipment.

heat screening.

providing a positive reaction.

ensuring that the different parts of the aircraft are maintained at a different potential.

ensuring that the different parts of the aircraft are maintained at the same potential.

the refuelling nozzle must be bonded to the fuel tank.

the bonding plug must be connected to the earth terminal.

the continuity between nozzle and hose must be infinity.

only use plastic nozzles.

to prevent compass malfunctioning and accumulation of local static charges.

to reduce the anodising effect.

to isolate all components electrically and therefore make static potential constant.

to provide a low resistance path for earth return circuits and safely dissipate local static charges and lightning strikes.
