Dear mathew we use earthing for protection of equipment as
well as operating person only if when fault current can
find its path to ground. in case of aeroplane there is no
nead of earthing as leakage current does not find ground
path. Second thing is that aircraft gets several million
volts of static charge when it flies in sky, hence it is
completely discharged with special dedicate discharge
system, when it lends to ground. Otherwise this charge may
get find path through passenger to ground, when they came
out of plane . It will cause immidiate death of passenger.
