Flybys are modeled as instantaneous changes in velocity.

The formula for [[delta]v.sub.emp] (1) gives three clues for properties that need to be satisfied by any theory that is developed to explain the flyby anomaly: 1) the theory must produce a speed-change that is proportional to the ratio [v.sub.eq]/c, 2) the anomalous force acting on the spacecraft must change the [lambda] component of the spacecraft's speed, and 3) the speed-change must be proportional to [v.sub.in].
