Morphology
The constituents 'ground' + 'loop' do cue a turning or circular movement on the ground, so a learner could plausibly infer some kind of ground-based spinning/turning. However, the specific technical sense — an abrupt, uncontrollable turn by an aircraft during landing or takeoff — is specialized and not fully predictable from the parts, making the expression only partially transparent to a B1 learner.
Etymology
Ground loop comes from the image of a plane suddenly spinning in a circle while still on the ground, almost like drawing a quick loop. That's why it means 'a sudden, uncontrolled turn' by a plane during landing or takeoff.
