echelon

An echelon is an arrangement of units or individuals resembling a series of steps, often seen in military formations or flight patterns. In aviation, it refers to a specific flight formation where each aircraft is positioned at a certain elevation and distance relative to the one ahead. This formation helps maintain separation and organization among aircraft. The term "echelon" can also refer to levels or grades within an organization, such as the upper echelons of management. The verb form, "to echelon," means to form or arrange in such a pattern.1234
