Serials: There may be times when a lift is too large to fly in one formation. In such cases the lift is organized into a number of serials. A serial is a tactical group of two or more aircraft but no more than six under the control of a serial commander (aviator) and separated from other tactical groupings within the lift by time or space. The use of serials may be necessary to maintain effective control of aviation assets.For example, if a Nap-of-the-Earth flight were used, it would be difficult to control 16 aircraft as a single increment. However, a 16 aircraft lift made up of four serials of four aircraft each could be more easily controlled.
