Morphology

GCA = G + C + A

This is an initialism whose letters (G, C, A) do not by themselves convey the meaning unless the expansion (e.g., 'ground-controlled approach') is known, so learners cannot derive the sense from the components.

Etymology

GCA is short for Ground-Controlled Approach, with ground meaning 'land', control meaning 'to guide', and approach meaning 'to come in to land'. So GCA is literally people on the ground guiding a plane to land with radar, which is why pilots ask for it in bad weather.
