3 Day Open Conference
Dranetz-BMI's PMIT and electrical conductivity on aircraft skin
Tuesday 18th November 2008
11.20 - 11.40
Auditorium 2
Aircraft must be safe, because danger in the sky may lead to catastrophic events. The requirements for uncompromising safety must also be fulfilled under extreme weather conditions: very low temperatures, snow, hail and electrical storms. In particular electrical storms are a demanding challenge for aviation instruments and avionics in general. Aircraft are equipped with a conductive outer skin that allows them to function as a “Faraday Cage”. Such an electrostatic screen provides aircraft with sufficient protection against lightning.
Therefore the Aircraft’s Faraday Cage must be checked regularly and even the worst case scenario when an aircraft is struck by lightning must be taken in consideration.. If the aircraft skin has too much resistance the Faraday Effect may be partially eliminated, if struck by high energy lightning. Small resistance measurements of a few Milliohm must be recognized and recorded. This presentation discusses products and methods used to perform these mandatory tests
