Plain English Meaning

ZISUR is the name of one specific point in the sky, identified on charts so pilots and controllers can talk about it without reading out latitude and longitude. Like all named waypoints, it is pronounceable, unique, and used in route clearances and flight plans.

Full Definition

ZISUR is a five-letter name code for a specific waypoint (a fixed geographic point defined by latitude and longitude) used in instrument flight procedures. It appears in FAA charts and route examples as a named fix that pilots and controllers can refer to by name rather than by coordinates.

Context Anchor

Seen in instrument procedure examples and in when selecting a point to fly directly toward.
