Meaning and Definition
An unwanted electrical current that flows between two or more points that are meant to be at the same electrical potential but are at different potentials due to improper grounding.
In aviation, a sharp uncontrollable turn of an aircraft on the ground, typically caused by a loss of directional control during landing or taxiing.

FAQ
Frequently Asked Questions
In aviation, yes, it can cause damage and injury. In electronics, it is not typically dangerous to people but can damage equipment and degrade signal quality.
Common solutions include using a ground loop isolator (transformer), ensuring all equipment is plugged into the same power circuit, or lifting the ground on one device (safety precautions apply).
Aircraft with conventional landing gear (tailwheel aircraft) are more prone to ground loops than those with tricycle gear, due to their centre of gravity being behind the main wheels.
Yes, especially in aviation jargon (e.g., 'The plane ground-looped'). In electronics, it's less common but possible (e.g., 'The system ground-looped').
An unwanted electrical current that flows between two or more points that are meant to be at the same electrical potential but are at different potentials due to improper grounding.
Ground loop is usually technical in register.
