Interference Path Lost

Description

Testing determines the levels of attenuation to radio frequency interference signals. These signals originate from inside the cabin, due to the increasing number of portable electronics allowed on board. This attenuation is necessary to reduce the effects of these signals on the radio antennas mounted outside of the aircraft.

DO-307 Test Methods

Back door Coupling Compliance
Back door coupling occurs when RF energy radiates from the PED and couples directly into the aircraft electrical equipment or wiring.

Front Door Coupling Compliance
Front door coupling occurs when RF energy radiates from the PED and couples directly inot the aircraft radio receiver antennas
