Multiple Choice

Radio equipment is bonded to the aircraft to provide a low impedance ground and to maximize radio interference from static electrical charges. True or False?

Bonding the radio equipment to the aircraft airframe creates a low impedance path for static electricity and lightning to equalize potentials across the system. When the aircraft accumulates static charges on surfaces or experiences discharge events, having a common, low-resistance ground prevents large voltage differences between radios, antennas, and other equipment. This minimizes radio interference caused by static and arcing, and helps maintain reliable communication and navigation performance. The practical goal is to reduce interference, not to maximize it, so bonding is used to keep RF noise and disturbances to a minimum.
