The flight conflict resolution and recovery is a key problem of free flight and air traffic control in the future. Given the current 3-dimensional position and velocity vectors of two aircrafts in predicted conflict and the required time of arrival （ETA） at the target point, some models of the conflict resolution and recovery in the geometric optimal and least maneuvers were proposed. These models not only resolve the flight conflict between two aircrafts hut also ensure the ETA constant. The feasibility of models is demonstrated by the simulation computation. These models can be used in airborne equipments and air traffic control automation system. By a mass of simulation with these models, some conflict resolution and recovery strategies in the limitation situation that the aircraft flight routes were tangent to the protection zone were summarized in tabulation suitable for air traffic controllers. Only considering some salty margin, these strategies can be used in the practical control by air traffic controllers,
