The Control method of turn with bank and calculated formula for turn performance are presented. Compared with bank turn, the characteristics of NBT is analyzed, operation approach for NBT is introduced, and the simplified calculated expression for mainly performance index of NBT is given finally. The model of dynamics for NBT is established, initial control algorithm for NBT is formed. The operation method and performance for NBT are validated based on aerodynamics model of aircraft, the advised method of improved turning is put forward.
