Plain English Meaning

A safety buffer between two parallel approach paths that no aircraft is allowed to enter. If a plane drifts into it, controllers immediately turn the aircraft on the next approach away to keep them apart.

Full Definition

A 2,000-foot wide protected airspace corridor centered between the final approach courses of two parallel instrument runways during simultaneous independent parallel approaches. Controllers continuously monitor both approach paths, and any aircraft observed penetrating the NTZ triggers an immediate breakout instruction to the threatened aircraft on the adjacent approach.
