Aircraft general knowledge

Dischargers can be placed

on the trailing edge of a

wing, as shown in the

picture here.

Static electricity can interfere with the electronic equipment on board the

aircraft.

8.6.1.1 Lightning

Statistics show that once every 1000 flight hours, large aircraft are struck by

lightning.

The lightning typically enters an outer point on the aircraft, e.g. in the nose.

The aircraft's fuselage can conduct the voltage from a lightning strike, so that the

voltage runs in the outer skin and leaves

the aircraft at the rear.

There are often wounds where the

lightning enters and where it leaves the

plane again.

8.6.2 Electrical theory

The purpose of this section is not to train you to be an electrical engineer, but to
refresh your knowledge from the time when you had physics in elementary

school.
